Detailed Description

In order that the above objects, features and advantages of the present disclosure may be more clearly understood, aspects of the present disclosure will be further described below. It should be noted that the embodiments and features of the embodiments of the present disclosure may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure, but the present disclosure may be practiced in other ways than those described herein; it is to be understood that the embodiments disclosed in the specification are only a few embodiments of the present disclosure, and not all embodiments.

For the convenience of understanding, it is first to be explained that any one of the methods for adjusting an airbag in a vehicle provided by the embodiments of the present disclosure may be applied to a case where the position of the airbag in the vehicle is adjustable. In particular, in such vehicles, the airbag is no longer fixedly arranged at the steering wheel, pillar or the like, but is movable relative to the vehicle (otherwise referred to as the relative position of the airbag to the vehicle frame being adjustable). There are a variety of hardware configurations that may enable movement of the airbag relative to the vehicle, and the present disclosure is not limited thereto. For example, a track may be arranged inside the vehicle, the airbag may be disposed on a slider that is slidable along the extending direction of the track, and the slider may be controlled to slide by a slider adjusting device, thereby achieving the purpose of adjusting the position of the airbag.

Fig. 1 is a flowchart of an airbag adjustment method in a vehicle according to an embodiment of the present disclosure. The method may be performed by a Vehicle controller, such as a Vehicle Control Unit (VCU) of the Vehicle. Referring to fig. 1, the method comprises the steps of:

and S110, acquiring pose parameter data of the current seat.

The posture parameter data of the seat specifically refers to parameter data capable of indicating the position, angle and the like of the whole seat. Fig. 2 and 3 are schematic views of two states of a seat provided by an embodiment of the present disclosure. Referring to fig. 2 and 3, the seat is composed of a plurality of components (e.g., a backrest 3, a seat cushion 4, a neck pillow 5, armrests 4, and a lower leg shield 1). Alternatively, the position and angle of each part relative to the vehicle frame can be used as the position and angle parameter data of the seat. Alternatively, the entire seat may be regarded as a set of points, and the position coordinates of each point with respect to the vehicle frame may be used as the position and orientation parameter data of the seat. This is not limited by the present application.

For example, if the position and the angle of each component relative to the vehicle frame are selected as the position and the angle of the seat, optionally, the position and the angle of the seat may include at least one of the following: the position and posture parameter data of the backrest, the position and posture parameter data of the cushion, the position and posture parameter data of the neck pillow, the position and posture parameter data of the armrest and the position and posture parameter data of the crus baffle.

The position and posture parameters of the backrest refer to parameters which can indicate the position, the angle and the like of the backrest relative to the vehicle frame, such as an included angle of the backrest. The included angle of the backrest specifically refers to the included angle between the plane of the backrest and the plane of the seat cushion.

The pose parameter data of the cushion refers to parameters such as the position and the angle of the cushion relative to the vehicle frame, such as height data of the cushion and front and back position data of the cushion. The height data of the seat cushion refers to the distance of the seat cushion relative to the lowest point of the vehicle frame. The front-rear position data of the seat cushion refers to the distance of the seat cushion relative to the foremost end of the vehicle frame.

The pose parameter data of the neck pillow refers to parameters such as the position, the angle and the like of the neck pillow relative to the vehicle frame, such as height data of the neck pillow. The height data of the neck pillow refers to the distance of the neck pillow relative to the lowest point of the vehicle frame.

The position and posture parameter data of the armrest refer to parameters which can indicate the position, the angle and the like of the armrest relative to the vehicle frame, such as height data of the armrest. The height data of the armrest refers to the distance of the armrest from the lowest point of the vehicle frame.

Referring to fig. 2 and 3, the lower leg shield 1 refers to a plate for providing support to the legs of the passenger. The shank baffle 1 is connected with the cushion 2, and the shank baffle 1 can overturn relative to the cushion 2. When the lower leg shield 1 is inverted to the condition shown in fig. 3, it can provide support for the passenger's legs.

The pose parameter data of the shank baffle refers to parameters which can indicate the position, the angle and the like of the shank baffle relative to the vehicle frame, such as included angle data of the shank baffle. The included angle data of the shank baffle plate refers to the included angle between the plane of the shank baffle plate and the plane of the cushion.

The pose parameter data of the current seat refers to an acquisition result obtained by acquiring the pose parameter data of the seat at the current moment.

There are various specific implementation methods for this step, and the present disclosure does not limit this. Illustratively, a posture sensor may be mounted on the seat. And acquiring pose parameter data of the current seat through the attitude sensor. Or, optionally, acquiring a seat adjustment parameter used in adjusting the seat; and obtaining pose parameter data of the current seat in the vehicle based on the seat adjustment parameters.

And S120, determining position adjustment parameter data of the safety air bag based on the pose parameter data of the current seat.

The position adjustment parameter data of the safety air bag is the basis for adjusting the position of the safety air bag. By "adjusting the position of the airbag" is to be understood, among other things, adjusting the position of the airbag relative to the frame of the vehicle. Illustratively, the target adjustment position of the airbag is taken as the position adjustment parameter data of the airbag.

The specific implementation method of this step is various, and exemplarily, a corresponding relationship between the pose parameter data of the seat and the position adjustment parameter data of the airbag is established in advance, and when this step is executed, the position adjustment parameter data of the airbag is determined based on the pose parameter data of the current seat and the corresponding relationship.

Optionally, the corresponding relationship between the position and orientation parameter data of the seat and the position adjustment parameter data of the airbag may be a correspondence table between the position and orientation parameter data of the seat and the position adjustment parameter data of the airbag. Or a functional relation between the pose parameter data of the seat and the position adjustment parameter data of the safety air bag.

Illustratively, a correspondence table of the posture parameter data of the seat and the position adjustment parameter data of the airbag is shown in table 1. In table 1, in the same row, the posture parameter data of the seat and the position adjustment parameter data of the airbag have correspondence, i.e., a corresponds to a, B corresponds to B, … …, and E corresponds to E.

TABLE 1

Pose parameter data of a seat	Position adjustment parameter data of an airbag
		A	a
B	b
		……	……
E	e

In S110, the pose parameter data of the current seat is obtained as B, and it can be determined that the position adjustment parameter data of the airbag corresponding to the pose parameter data B of the current seat is B, which is determined by the lookup table 1.

Optionally, the corresponding relationship between the position and orientation parameter data of the seat and the position adjustment parameter data of the airbag may be specifically a functional relationship between the position and orientation parameter data of the seat and the position adjustment parameter data of the airbag. Illustratively, assuming that the position and posture parameter data of the seat is X and the position adjustment parameter data of the airbag is Y, a function of Y with respect to X is established through big data analysis, and is expressed as Y ═ f (X). When S110 is executed, the position and orientation parameter data of the current seat is obtained as X1, X in Y ═ F (X) is replaced with X1, F (X1) is solved, and Y1 ═ F (X1) is obtained as Y1.

In practice, the postures of passengers are different, and the postures of seats are different. Therefore, by utilizing a big data technology, the most possible sitting posture of the passenger at present can be reversely deduced through the position and posture parameter data of the present seat, so that the position of each safety air bag can be well protected according to the most possible sitting posture of the passenger at present, and the corresponding relation between the position and posture parameter data of the seat and the position adjustment parameter data of the safety air bag is established.

Optionally, on the basis of the above technical solution, optionally, the step further includes: and determining position adjustment parameter data of the safety air bag based on the pose parameter data of the current seat and the running state of the current vehicle. The current running state of the vehicle may specifically include a vehicle stop state and a vehicle movement state. For example, it may be provided that the position of the airbag is not adjusted when the vehicle is in a stopped state; when the vehicle is in a moving state, the position of the safety airbag is adjusted and adjusted. The reason for this is that, in practice, the passenger sometimes does not attend the seat, and the purpose of adjusting the posture of the seat is only to facilitate fetching of the article and the like. In this case, the position of the airbag is not adjusted. On one hand, the energy consumption can be saved, and the situation is particularly suitable for electric automobiles; on the other hand, the movement of the airbag may cause the blocking of the sight line of the passenger, and the reduction of the activity space, which affects the user experience.

And S130, adjusting the position of the safety air bag based on the position adjustment parameter data of the safety air bag.

In this step, the position of the airbag is adjusted, including at least one of:

firstly, the corresponding relation between the safety air bag and the seat needing protection is adjusted. Specifically, in execution of S120, based on the pose parameter data of the current seat, it can be determined whether or not each seat is occupied by a passenger. And further, the corresponding relation between the airbag and the seat is determined according to whether the passenger is seated in each seat. When this step is executed, the position of the airbag is adjusted so as to satisfy the correspondence relationship between the airbag and the seat. For example, assuming that 4 airbags are provided in the vehicle in total, if it is determined that only the driver seat has a passenger at the time of performing S120, it is determined that the 4 airbags each correspond to the driver seat. In performing this step, the position of each airbag is adjusted so that each airbag is used to protect the occupant of the driver's seat. When executing S120, it is determined that only the driver seat and the passenger seat have passengers, 2 airbags are determined to correspond to the driver seat, and the other 2 airbags are determined to correspond to the passenger seat. When this step is performed, the positions of the airbags are adjusted so that 2 airbags are used to protect the passenger in the driver's seat and the other 2 airbags are used to protect the passenger in the passenger's seat.

Secondly, the relative position of the safety air bag and the appointed seat is adjusted. For example, if an airbag is used to provide support to the chest of an occupant in a given seat after inflation. Regardless of how the designated seat is adjusted, with the method provided by the present disclosure, the position of the airbag is adjusted so that the airbag always provides a supporting force for the chest of the occupant in the designated seat after being inflated.

The essence of the technical scheme is that the position of the safety air bag is adjusted according to the position and posture of the current seat, so that the position of the safety air bag can be changed according to the sitting posture change of a passenger, and the passenger protection effect in the collision is improved.

Optionally, the above technical solution further includes: determining the inflation data of the safety airbag based on the pose parameter data of the current seat; and inflating the safety airbag based on the inflation quantity data of the safety airbag. Among them, "inflating the airbag" is essentially pre-inflating the airbag so that the airbag is slightly inflated. The degree of expansion of the pre-inflated airbag is less than the degree of expansion of the airbag in the event of a collision. Because the statures of different persons vary greatly. For persons with a particularly thin size, or persons with a particularly small size (e.g. children), the pre-inflation serves the purpose of limiting the range of motion. Therefore, once collision occurs, on one hand, the time spent by the airbag to expand to a degree enough to protect the passenger can be reduced, and on the other hand, the impact force to the passenger during collision can be reduced, so that the effect of protecting the passenger is achieved.

It should be noted that, in the scheme of adjusting the inflation amount of the airbag, because the volume of the gas inflated in the airbag needs to be controlled, an inflator and a vacuum pump may be provided in the vehicle, the inflator is connected to the gas inlet of the airbag, and the vacuum pump is connected to the gas outlet of the airbag. The air bag is inflated by controlling the working state of the air pump. The air is pumped out from the safety air bag by controlling the working state of the vacuum pump.

Alternatively, in practice, it may be provided that each airbag comprises a plurality of inflatable chambers. When the inflation quantity of the safety air bag is adjusted, one or more inflatable cavities can be selectively inflated. The purpose of this arrangement is to selectively inflate the inflation chamber according to the stature characteristics of the passenger, so that the pre-inflated airbag fits better with the stature of the passenger, and further improve the protection effect on the passenger.

Alternatively, in order to make it convenient to inflate and deflate the airbag, in practice, a storage container may not be provided for the airbag, and the airbag is directly exposed in the seating space.

FIG. 4 is a flow chart of another method of airbag adjustment in a vehicle provided by an embodiment of the present disclosure. Fig. 4 is a specific example of fig. 1. Referring to fig. 4, the method for adjusting an airbag in a vehicle includes:

and S210, obtaining a seat adjusting instruction.

The seat adjustment instruction is a control signal according to which the vehicle controller adjusts the position and orientation of a seat in the vehicle.

There are various specific implementation methods of this step, and this application does not limit this. Illustratively, the specific implementation method of this step may be: acquiring voice control information or key operation information input by a user; and generating a seat adjusting instruction based on the voice control information or the key operation information.

Illustratively, the user speaks a voice command such as "adjust the backrest angle", "move the seat forward by 5 centimeters" to the vehicle central control device, and the vehicle central control device converts the voice command into a seat adjustment command and sends the seat adjustment command to the vehicle control unit. Or, the user clicks a key for adjusting the seat on the vehicle, and the vehicle central control equipment converts a signal input by the key into a seat adjusting instruction and sends the seat adjusting instruction to the vehicle control unit.

Optionally, if a pressure sensor is installed in the seat; the specific implementation method of the step can also be as follows: acquiring pressure measurement data acquired by a pressure sensor; based on the changing characteristics of the pressure measurement data, seat adjustment instructions are generated. For example, if a pressure sensor is installed in the backrest, when the user wishes to increase the backrest angle, the user applies force to lean the waist back against the backrest. At this time, the pressure value measured by the pressure sensor gradually increases. According to the characteristic that the pressure value is gradually increased, an instruction for increasing the backrest included angle is generated. When the user wishes to decrease the backrest angle, the user lifts the back up so that the back is away from the backrest. At this time, the pressure value measured by the pressure sensor gradually decreases. According to the characteristic that the pressure value is gradually reduced, an instruction for reducing the backrest included angle is generated.

Further, on the basis of the above technical solution, before generating the seat adjustment instruction based on the variation trend of the pressure measurement data, the method further includes: judging whether a passenger is currently admitted; generating a seat adjusting instruction based on the variation trend of the pressure measurement data, and replacing the seat adjusting instruction with: and if a passenger is present, generating a seat adjusting instruction based on the variation trend of the pressure measurement data. The purpose of the arrangement is to realize that no seat adjusting instruction is generated and no seat adjustment is carried out when a passenger is not in a seat; only after the passenger is in the seat, a seat adjusting instruction is generated to adjust the seat. This arrangement can save energy consumption.

Optionally, there are various methods for determining whether a passenger is currently seated, and for example, a camera installed in a vehicle and having a camera area covering the passenger seat may be used to capture an image, and whether a passenger is currently seated may be determined by analyzing an image capture result. For example, if the image acquired by the current camera shows the shadow of the passenger, it is determined that the passenger is currently present, otherwise, no passenger is present.

Optionally, whether a passenger is present or not may be determined according to a magnitude relationship between a pressure value acquired by a pressure sensor installed in the seat and a set value. For example, if the pressure value collected by the pressure sensor is greater than the set value, it is determined that a passenger is currently present, otherwise, no passenger is present.

And S220, responding to the seat adjusting instruction, and adjusting the seat pose in the vehicle.

It should be noted that in practice, the adjustment of the seat by the passenger is usually not adjusted to the most comfortable position at one time, but the passenger reaches the most comfortable position in the continuous "adjustment-feel-adjustment-feel". Therefore, in practice, S210 and S220 are often repeatedly performed until the seat position in the vehicle is adjusted to a state that is satisfied by the passenger.

And S230, acquiring pose parameter data of the current seat after the seat pose in the vehicle is adjusted.

Here, the phrase "the seat posture in the vehicle is adjusted completely" is understood to mean that the seat posture in the vehicle is adjusted to a state that is satisfied by the passenger.

And S240, determining position adjustment parameter data of the safety air bag based on the pose parameter data of the current seat.

And S250, adjusting the position of the safety air bag based on the position adjustment parameter data of the safety air bag.

The essence of the technical scheme is that the seat pose is adjusted firstly, and the position of the safety air bag is adjusted after the seat pose is adjusted to a comfortable state. The position adjustment parameter data of the safety air bag is determined based on the position and posture parameter data of the current seat. In practice, the adjustment of the seat by the passenger is usually not done once to the most comfortable position, but the passenger reaches the most comfortable position in the continuous "adjust-feel-adjust-feel". Therefore, if the airbag follows the adjustment in the process of adjusting the seat position, the airbag may block the view of the passenger, affect the movement space of the passenger, and affect the user experience. By adopting the scheme, the bad phenomena that the safety air bag shields the vision of the passenger and influences the activity space of the passenger in the process of adjusting the seat can be avoided, and the user experience is improved.

Optionally, on the basis of the above technical solution, before S210, the method further includes performing authority authentication on the passenger, and after the authority authentication is passed, performing S210.

Optionally, it may be further configured to disallow adjustment of the seat if the authority authentication fails. Or only allow the passenger to manually adjust the seat. At present, the condition that the car owner uses a private car for network appointment or temporarily borrows the car often occurs, and the authority of the car owner and the passenger is not distinguished. The authority identification can be realized for the vehicle owner and the passenger so as to improve the attribution feeling of the vehicle owner.

The authority authentication method has various methods, for example, a voice or a button instruction is used for controlling the vehicle to issue a mobile phone verification code to a passenger mobile phone, and the passenger inputs the mobile phone verification code to perform authority authentication. Or the authority setting is carried out through the vehicle center console in advance. In the process of authority setting, the vehicle stores information which is related to passengers and can be subjected to authority authentication, such as fingerprints, face prints, voiceprints, passwords or pin codes. When authority authentication is performed, a fingerprint, a face print, a voiceprint, a password, a pin code, or the like is input to perform the authority authentication. These methods of authority authentication, in essence, ensure the security of authority authentication through encryption technology, and make authority authentication executable.

Further, the position and posture parameter data of the seats that the passengers conventionally use may be previously associated with the passengers. After the passenger authority authentication is passed, S210-S230 can be replaced by: and calling the position and posture parameter data of the seat in the vehicle corresponding to the passenger passing the authority authentication. The automatic and quick adjustment of the seat can be realized by the arrangement, and the user experience is further improved.

Alternatively, in practice, the same seat may be provided for one or more authorized passengers. And the position and posture parameter data of one passenger corresponding to one or more seats. That is, one passenger authority corresponds to the pose of one or more seats.

Fig. 5 is a flow chart of a method of seat adjustment provided by an embodiment of the present disclosure. Fig. 3 is a view showing fig. 5, and the method of seat adjustment includes:

and S301, setting authority.

Alternatively, the authority setting is made only for the front passenger seat. This is because the passenger seat tends to have a large space relative to the rear seats, and the passenger seat adjustment has little influence on the main driver seat and the rear seats.

And S302, after the passenger gets on the bus, the passenger is authorized. If the authority authentication is passed, executing S303, otherwise executing S304.

Alternatively, the passenger may be set to start the "adjustment of the passenger seat with body posture" function immediately after the passenger sits in the passenger seat, or start the "adjustment of the passenger seat with body posture" function after a certain period of sitting (the time length of which can be customized).

For example, when the 'assistant driver seat adjusts with body posture' function is started, the user can be guided to confirm whether the 'assistant driver seat adjusts with body posture' function needs to be started by playing voice information or displaying prompt information by using a center console display screen. The user may confirm by "voice control" or "click". And if the user confirms that the function of adjusting the assistant driver seat along with the body posture needs to be started, entering an authority authentication interface and performing authority authentication on the passenger.

And S303, inquiring whether the backrest position is adjusted or not, and receiving an instruction input by a user. If the user confirms that the backrest position needs to be adjusted, executing S305; if the user confirms that the backrest position does not need to be adjusted, S306 is executed.

And S304, entering a manual seat adjusting mode of the passenger.

S305, adjusting the position of the backrest.

Optionally, the passenger leans against the backrest by raising the backrest or exerting force on the backrest, so that the pressure value measured by the pressure sensor at the backrest changes, the backrest position adjustment parameter is determined according to the change characteristic of the pressure value, the position of the backrest is adjusted until the backrest is adjusted to a comfortable position, and the user confirms the current backrest state in a voice or key mode.

S306, inquiring whether the position of the seat cushion is adjusted or not, and receiving an instruction input by a user. If the user confirms that the position of the seat cushion needs to be adjusted, S307 is executed; if the user confirms that the adjustment of the seat cushion position is not required, S308 is executed.

And S307, adjusting the position of the seat cushion.

Optionally, the passenger lifts up or presses thigh or buttock hard downwards to make the pressure value that the pressure sensor of cushion department measured change, through the change characteristic of pressure value, confirm cushion position adjustment parameter, adjust the position of cushion until adjusting the cushion to comfortable position, the user confirms current cushion state through pronunciation or button form.

S308, inquiring whether to adjust the position of the neck pillow or not, and receiving an instruction input by a user. If the user confirms that the position of the neck pillow needs to be adjusted, executing S309; if the user confirms that the adjustment of the neck pillow position is not required, S310 is performed.

S309, adjusting the position of the neck pillow.

Optionally, the passenger lifts up or leans against the head backward to make the pressure value that pressure sensor of neck pillow department measured change, through the change characteristic of pressure value, confirm neck pillow position adjustment parameter, adjust the position of neck pillow, until adjusting the neck pillow to comfortable position, the user confirms current neck pillow state through pronunciation or button form.

S310, inquiring whether to adjust the position of the crus baffle or not, and receiving an instruction input by a user. If the user confirms that the position of the shank baffle needs to be adjusted, S311 is executed; if the user confirms that the adjustment of the position of the lower leg baffle is not needed, S312 is executed.

S311, adjusting the position of the lower leg baffle.

Optionally, the passenger opens the lower leg baffle in front of the seat by lifting the lower leg or applying force downwards, and changes the pressure value measured by the pressure sensor at the lower leg baffle, and determines the position adjustment parameter of the lower leg baffle according to the change characteristic of the pressure value, and adjusts the position of the lower leg baffle until the lower leg baffle is adjusted to a comfortable position, and the user confirms the current state of the lower leg baffle in a voice or key form.

And S312, inquiring whether the position of the armrest is adjusted or not, and receiving an instruction input by a user. If the user confirms that the position of the armrest needs to be adjusted, S313 is executed; if the user confirms that the armrest position does not need to be adjusted, S314 is performed.

And S313, adjusting the position of the armrest.

Optionally, the passenger can raise or lower the arm to change the pressure value measured by the pressure sensor at the armrest, determine the armrest position adjustment parameter according to the change characteristic of the pressure value, adjust the position of the armrest until the armrest is adjusted to the comfortable position, and confirm the current armrest state through voice or key pressing.

And S314, inquiring whether to memorize the current seat position or not, and receiving an instruction input by a user. If the user confirms that the current seat position needs to be memorized, S315 is executed; if the user confirms that the current seat position does not need to be memorized, S316 is performed.

The purpose of memory is to establish the corresponding relation between passengers and the current seat pose parameter data. And if the passenger is admitted again and the authority passes the authentication, the corresponding relation between the passenger and the seat pose parameter data is directly called to adjust the position of the seat without executing S303-S313.

And S315, storing the position of the current seat, and establishing a corresponding relation between the passenger and the position and posture parameter data of the current seat.

The seat adjusting mode can realize intelligent and rapid seat adjustment and improve user experience.

Optionally, on the basis of the above technical method, it is set that after the user adjusts the backrest, the seat cushion, the neck pillow, the lower leg baffle or the armrest through the lifting or lowering operation, once the user confirms that the body posture reaches a certain range, the adjustment mode is automatically started again. Or the adjustment mode is started again in the form of manual buttons or voice instructions, otherwise, the body posture is adjusted in a small range, and the seat is not adjusted with the body posture any more.

In fig. 5, the positions of the components are adjusted in order of the backrest, the seat cushion, the neck pillow, the lower leg links, and the armrests, for example. This is only one specific example of the disclosure and is not limiting of the disclosure. In practice, the backrest, the seat cushion, the neck pillow, the lower leg shield, and the armrests may be arranged in any order, and then the positions of the respective members may be adjusted in order of the arrangement.

Fig. 6 is a block diagram of an airbag adjustment apparatus in a vehicle according to an embodiment of the present disclosure. Referring to fig. 6, the apparatus includes a seat pose parameter acquisition module 610, an airbag adjustment parameter determination module 620, and an airbag adjustment module 630.

The seat pose parameter acquisition module 610 is configured to acquire pose parameter data of a current seat in the vehicle.

The posture parameter data of the seat specifically refers to parameter data capable of indicating the position, angle and the like of the whole seat. Referring to fig. 2 and 3, the seat is composed of a plurality of components (e.g., a backrest 3, a seat cushion 4, a neck pillow 5, armrests 4, and a lower leg shield 1). Alternatively, the position and angle of each part relative to the vehicle frame can be used as the position and angle parameter data of the seat. Alternatively, the position and angle of the entire seat with respect to the frame of the vehicle may be used as the positional and orientational parameter data of the seat. This is not limited by the present application.

Alternatively, if a seat is equipped with a posture sensor. The seat pose parameter acquiring module 610 is specifically configured to acquire pose parameter data of a current seat through a posture sensor. Or, optionally, the seat pose parameter acquiring module 610 is specifically configured to acquire a seat adjustment parameter used when the seat is adjusted; and obtaining pose parameter data of the current seat in the vehicle based on the seat adjustment parameters.

And the airbag adjustment parameter determining module 620 is configured to determine position adjustment parameter data of the airbag based on the pose parameter data of the current seat.

The data of the position adjustment parameters of the safety air bag are the basis for adjusting the safety air bag and comprise the parameters for adjusting the position of the safety air bag. By "adjusting the position of the airbag" is to be understood, among other things, adjusting the position of the airbag relative to the vehicle frame. Illustratively, the target adjustment position of the airbag is taken as the position adjustment parameter data of the airbag.

Illustratively, a corresponding relationship between the position and orientation parameter data of the seat and the position adjustment parameter data of the airbag is pre-established, and the airbag adjustment parameter determining module 620 is specifically configured to determine the position adjustment parameter data of the airbag based on the position and orientation parameter data of the current seat and the corresponding relationship.

Alternatively, the corresponding relationship between the position and orientation parameter data of the seat and the position adjustment parameter data of the airbag may be a correspondence table between the position and orientation parameter data of the seat and the position adjustment parameter data of the airbag, or a functional relationship between the position and orientation parameter data of the seat and the position adjustment parameter data of the airbag.

Optionally, on the basis of the foregoing technical solution, optionally, the airbag adjustment parameter determining module 620 is specifically configured to: and determining position adjustment parameter data of the safety air bag based on the pose parameter data of the current seat and the running state of the current vehicle. The current running state of the vehicle may specifically include a vehicle stop state and a vehicle movement state. For example, it may be provided that the position of the airbag is not adjusted when the vehicle is in a stopped state; when the vehicle is in a moving state, the position of the safety airbag is adjusted and adjusted. The reason for this is that, in practice, the passenger sometimes does not attend the seat, and the purpose of adjusting the posture of the seat is only to facilitate fetching of the article and the like. In this case, the position of the airbag is not adjusted. On one hand, the energy consumption can be saved, and the situation is particularly suitable for electric automobiles; on the other hand, the movement of the airbag may cause the blocking of the sight line of the passenger, and the reduction of the activity space, which affects the user experience.

And an airbag adjusting module 630, configured to adjust a position of the airbag based on the position adjustment parameter data of the airbag.

Optionally, on the basis of the above technical solution, optionally, the airbag adjustment parameter determining module 620 is further configured to determine inflation data of the airbag based on pose parameter data of the current seat; the airbag adjusting module 630 is further configured to inflate the airbag based on the inflation data of the airbag.

Among them, "inflating the airbag" is essentially pre-inflating the airbag so that the airbag is slightly inflated. The degree of expansion of the pre-inflated airbag is less than the degree of expansion of the airbag in the event of a collision. Because the statures of different persons vary greatly. For persons with a particularly thin size, or persons with a particularly small size (e.g. children), the pre-inflation serves the purpose of limiting the range of motion. Therefore, once collision occurs, on one hand, the time spent by the airbag to expand to a degree enough to protect the passenger can be reduced, and on the other hand, the impact force to the passenger during collision can be reduced, so that the effect of protecting the passenger is achieved.

Fig. 7 is a block diagram of another airbag adjustment apparatus in a vehicle according to an embodiment of the present disclosure. Fig. 7 is a specific example of fig. 6. Referring to fig. 7, the method for adjusting an airbag in a vehicle includes a seat adjustment instruction obtaining module 710, a seat adjustment module 720, a seat pose parameter obtaining module 730, an airbag adjustment parameter determining module 740, and an airbag adjustment module 750.

The seat adjustment instruction obtaining module 710 is configured to obtain a seat adjustment instruction.

Illustratively, the seat adjustment instruction obtaining module 710 is configured to obtain voice control information or key operation information input by a user; and generating a seat adjusting instruction based on the voice control information or the key operation information.

Optionally, if a pressure sensor is installed in the seat; the seat adjustment instruction acquisition module 710 is configured to acquire pressure measurement data acquired by the pressure sensor; based on the changing characteristics of the pressure measurement data, seat adjustment instructions are generated. For example, if a pressure sensor is installed in the backrest, when the user wishes to increase the backrest angle, the user applies force to lean the waist back against the backrest. At this time, the pressure value measured by the pressure sensor gradually increases. According to the characteristic that the pressure value is gradually increased, an instruction for increasing the backrest included angle is generated. When the user wishes to decrease the backrest angle, the user lifts the back up so that the back is away from the backrest. At this time, the pressure value measured by the pressure sensor gradually decreases. According to the characteristic that the pressure value is gradually reduced, an instruction for reducing the backrest included angle is generated.

Further, the seat adjustment instruction obtaining module 710 is configured to obtain pressure measurement data collected by the pressure sensor; judging whether a passenger is currently admitted; and if a passenger is present, generating a seat adjusting instruction based on the variation trend of the pressure measurement data. The purpose of the arrangement is to realize that no seat adjusting instruction is generated and no seat adjustment is carried out when a passenger is not in a seat; only after the passenger is in the seat, a seat adjusting instruction is generated to adjust the seat. This arrangement can save energy consumption.

The seat adjustment module 720 is configured to adjust a seat pose in the vehicle in response to the seat adjustment instruction.

It should be noted that in practice, the adjustment of the seat by the passenger is usually not adjusted to the most comfortable position at one time, but the passenger reaches the most comfortable position in the continuous "adjustment-feel-adjustment-feel". Therefore, in practice, the seat adjustment instruction acquisition module 710 and the seat adjustment module 720 are often operated repeatedly until the seat position in the vehicle is adjusted to the state satisfied by the passenger.

The seat pose parameter acquiring module 730 is configured to acquire pose parameter data of a current seat after adjustment of a seat pose in the vehicle is completed.

The airbag adjustment parameter determining module 740 is configured to determine position adjustment parameter data of an airbag based on the pose parameter data of the current seat.

The airbag adjusting module 750 is configured to adjust a position of the airbag based on the airbag position adjustment parameter data.

Optionally, on the basis of the above technical solution, before obtaining the seat adjustment instruction, the method further includes performing authority authentication on the passenger, and after the authority authentication is passed, obtaining the seat adjustment instruction is executed.

Further, the position and posture parameter data of the seats that the passengers conventionally use may be previously associated with the passengers. And after the authority authentication of the passenger passes, directly calling the position and attitude parameter data of the seat in the vehicle corresponding to the passenger passing the authority authentication. The automatic and quick adjustment of the seat can be realized by the arrangement, and the user experience is further improved.
