Description
Technical Field
The present invention relates to a control technology of vehicle horn volume, and more particularly, to a method, apparatus and system for adaptively controlling vehicle horn volume. Furthermore, the invention relates to a vehicle comprising a system for adaptively controlling the vehicle horn volume or comprising at least one device for adaptively controlling the vehicle horn volume. The invention also relates to a corresponding data processing device and to a corresponding computer-readable storage medium.
Background
As the number of vehicles continues to grow, the problem of noise pollution of vehicle horns becomes more and more serious, and conventional vehicle horns generally only emit a decibel level of sound, which is prone to cause excessive noise and discomforts such as disconcerting to pedestrians. To prevent this, many countries and regions limit the volume of the vehicle horn to some extent.
If the volume of the horn is too small, the sound of the horn is not clear enough under certain conditions, and potential safety hazards are brought to driving. Therefore, it is an urgent need to solve the problem of designing a control technique for the volume of a vehicle horn, which can adaptively control the volume of the vehicle horn based on different situations of a front object.
If the image sensor is used to collect the image information of the environment around the vehicle and then the image analysis is performed to distinguish the type of the object (such as a vehicle or a pedestrian) and the distance between the object and the vehicle, such methods are firstly low in recognition rate and large in computation amount and slow in speed. Therefore, during development, the inventor finds that the adaptive control of the volume of the vehicle horn can be realized by using a simple and efficient method and system.
Disclosure of Invention
In order to solve the problems of the prior art, the invention provides a method, a device and a system for adaptively controlling the volume of a horn of a vehicle. The technical scheme is as follows:
according to a first aspect of the present invention, there is provided a method for adaptively controlling the volume of a vehicle horn, the method comprising: acquiring vehicle positioning information; acquiring electronic map information; acquiring related information for controlling the volume of a vehicle horn based on the vehicle positioning information and the electronic map information; and determining the volume of the vehicle horn according to the relevant information for controlling the volume of the vehicle horn.
The invention provides a vehicle horn volume self-adaptive control system based on the position of a vehicle, aiming at the problem that the volume of a vehicle horn is not adjustable at present. According to the method, according to vehicle positioning information, relevant information for controlling the volume of a horn of a vehicle, such as information relevant to the current running environment of the vehicle, is extracted from an electronic map, such as a vehicle-mounted navigation map, wherein the information can be road speed limit information or attribute information of an area where the vehicle is located, the volume of the horn under different conditions is determined, and then whether the volume of the horn needs to be adjusted or not and the adjustment amount of the volume are judged. Thus, adaptive adjustment of the vehicle horn volume is achieved.
For example, when the vehicle is traveling on a highway with a speed limit of 120 kilometers per hour (km/h), the volume of the horn may be increased accordingly to ensure that other road users can receive the sound emitted by the horn. When the vehicle is in the residential district, the road speed limit is 15km/h, and the volume of the vehicle horn is also correspondingly set (the volume is reduced as much as possible). Therefore, the invention can meet the requirement of sufficient volume early warning, ensure the driving safety of vehicles, reduce the volume as much as possible, reduce the noise pollution to a certain extent and avoid the discomfort of nearby pedestrians as much as possible.
According to the present invention, the information related to the control of the volume of the horn of the vehicle may be, for example, information or parameters related to the current running environment of the vehicle. Optionally, the information related to controlling the volume of the horn of the vehicle includes: road speed limit information; and/or region attribute information; and/or volume limit information.
By extracting attribute information of an area where the vehicle is located from the vehicle-mounted navigation map, for example, a horn no-sounding area of the vehicle or other areas with specified limits on noise, the volume of the horn of the vehicle is set accordingly (for example, the volume is reduced to a preset minimum value).
Optionally, when the acquired information related to controlling the volume of the vehicle horn is road speed limit information, the step "determining the volume of the vehicle horn according to the information related to controlling the volume of the vehicle horn" includes:
acquiring a corresponding relation between a preset road speed limit and the volume of a vehicle horn;
and determining the volume of the vehicle horn according to the acquired road speed limit information.
Optionally, when the acquired information related to the control of the vehicle horn volume is road speed limit information, the step "determining the vehicle horn volume according to the information related to the control of the vehicle horn volume" includes:
acquiring a corresponding relation between a preset road speed limit and a vehicle horn volume adjustment amount;
determining the volume adjustment amount of a vehicle horn according to the current road speed limit information;
and calculating the volume of the vehicle horn according to the volume adjustment amount of the vehicle horn.
Optionally, when the acquired information related to controlling the volume of the vehicle horn is area attribute information, the step "determining the volume of the vehicle horn according to the information related to controlling the volume of the vehicle horn" includes:
acquiring a corresponding relation between a preset area attribute and the volume of a vehicle horn;
and determining the volume of the vehicle horn according to the acquired current region attribute.
Optionally, the vehicle horn volume decreases, in particular stepwise or linearly, with decreasing road speed limit; preferably, the vehicle horn volume is below a predetermined limit value, which is preferably selected based on the zone property information.
As described above, the road section with a low speed limit is usually a residential area, a school, a hospital, or the like, and on the premise of ensuring safety, noise pollution can be reduced by appropriately reducing the volume, thereby promoting the quality of life of surrounding residents.
It is advantageous to select the predetermined limit value on the basis of the zone property information, for example when the vehicle is currently in the vicinity of a school, to set the limit value accordingly to a lower volume value, for example 60 db. When the vehicle is currently on a highway, the limit value is set accordingly to a higher volume value, for example, 120 db. Whereby the sound volume can be well limited to a reasonable range.
Optionally, when the acquired relevant information for controlling the volume of the vehicle horn is road speed limit information and area attribute information;

Optionally, when the acquired information related to controlling the volume of the vehicle horn is volume limit information, the step "determining the volume of the vehicle horn according to the information related to controlling the volume of the vehicle horn" includes:
the volume of the vehicle horn is made at least below the volume limit according to the volume limit information.
For example, in the area in which the vehicle is currently located, if the sound volume is to be below 60 db, the limit value for the sound volume of the vehicle horn is automatically adjusted to 60 db. Corresponding regulations can thus be complied with well, avoiding violations. Optionally, the method further comprises:
acquiring the current running speed of the vehicle;
determining the volume of a vehicle horn according to the current running speed of the vehicle;
preferably, the vehicle horn volume increases, in particular stepwise or linearly, with an increase in the current driving speed of the vehicle.
It is advantageous to take into account the current driving speed of the vehicle when determining the volume of the horn of the vehicle, because as the current driving speed of the vehicle increases, the probability of a traffic accident occurring and the degree of damage to the accident increase to some extent. Therefore, when the current running speed of the vehicle is increased, the volume of the vehicle horn is adaptively increased, so that the warning effect can be effectively improved, and meanwhile, when the current running speed of the vehicle is lower, the volume of the vehicle horn is adaptively kept at a lower level, so that the noise pollution is reduced.
In addition, the current running speed of the vehicle can be simply and feasibly obtained by only reading parameters from a vehicle speed sensor existing in the vehicle, and no additional speed measuring equipment is needed.

FIG. 1 is a flow chart of a method 100 for adaptively controlling the volume of a vehicle horn in accordance with an embodiment of the present invention. Before describing FIG. 1, it should be noted that the flow diagrams shown herein are described by way of example, but that the operational steps may be performed in any system and are not limited to this scenario. Additionally, the flow chart in fig. 1 shows an example of the operational steps being performed in a particular order, as indicated by the lines connecting the blocks, but the various steps shown in the chart may be performed in any order or in any combination or sub-combination. It should be understood that in some embodiments, some of the steps described below may be combined into a single step. In some embodiments, one or more additional steps may be included.
According to the invention, in step 101, vehicle positioning information is acquired from a vehicle-mounted positioning device (such as a GPS, Beidou positioning device).
In step 102, electronic map information, such as navigation map data, is read. The navigation map may be stored in the in-vehicle system in advance, or may be downloaded from a server that provides map data to the in-vehicle system through a communication network. The navigation map data includes a variety of information describing roads and objects (e.g., data classes defined in the navigation data standard NDS). Which may contain at least road speed limit information and/or zone attribute information and/or volume limit information.
In step 103, based on the vehicle positioning information and the electronic map information, the map information of the current position of the vehicle is found, and relevant information that can be used for controlling the volume of the vehicle horn is obtained, for example: road speed limit information and/or zone attribute information and/or volume limit information.
Then, in step 104, the vehicle horn volume is set based on the road speed limit information and/or the zone attribute information and/or the volume limit information.
Specifically, when the acquired relevant information for controlling the volume of the vehicle horn is road speed limit information, acquiring a corresponding relation between a preset road speed limit and a vehicle horn volume adjustment amount; determining the volume adjustment amount of a vehicle horn according to the current road speed limit information; and calculating the volume of the vehicle horn according to the volume adjustment amount of the vehicle horn. The volume of the horn may be proportional to the road speed limit information. That is, if the speed of the road on which the vehicle is currently located is limited to 30km/h, it is likely to travel in a residential area, or in an area where there are many pedestrians and the road is narrow. This may reduce the volume of the vehicle horn (e.g., to 90 dB). Similarly, if the speed limit of the road on which the vehicle is currently located is high, for example 100km/h (motorway), the volume of the vehicle horn may be adjusted correspondingly high, for example to 110 dB.
When the acquired related information for controlling the volume of the vehicle horn is area attribute information, acquiring a corresponding relation between a preset area attribute and the volume of the vehicle horn; and determining the volume of the vehicle horn according to the acquired current region attributes (such as a horn no-sounding region or regions needing to reduce the volume of the horn in schools, hospitals and the like). For example, if the area where the vehicle is currently located is a horn no-sound area, the volume of the horn of the vehicle is adjusted to be as small as possible, for example, a volume that cannot be recognized by human ears, so that corresponding regulations are well followed, and violation is avoided.
Furthermore, different vehicle horn volumes can be set for different types of areas, in particular taking into account relevant traffic regulations. For example, when the vehicle is in a residential area, school, hospital, etc., the vehicle horn volume is set at a low level, for example, 60 db. For example, when the vehicle is in a business, industrial, or the like area, the vehicle horn volume is set at a medium level, for example, 80 db. For example, when the vehicle is in an area such as a highway, a city expressway, a main road, etc., the vehicle horn volume is set at a high level, for example, 100 db.
Therefore, the map data can meet the requirement of sufficient volume early warning under certain conditions (such as expressways, urban expressways and main roads) according to the map data, and the driving safety of vehicles is ensured; the volume of the horn can be reduced as much as possible in a road section or a special area with a lower speed limit, and the volume of the horn for pedestrians is controlled not to be too large, so that the noise pollution is reduced.
Therefore, the volume of the vehicle horn can be adaptively controlled in real time, so that the vehicle horn can adaptively emit sounds with different decibels according to the preset control relationship between the volume decibel and the relevant information for controlling the volume of the vehicle horn under different conditions according to the vehicle positioning information and the electronic map information. The adaptive control method not only realizes the functionality of the vehicle horn, but also ensures that excessive noise pollution is not produced. The safety of the vehicle in running in various environments is enhanced, the driving behavior is more civilized, and the functional design of the vehicle-mounted driving auxiliary system is enriched.
Fig. 2 is a schematic block diagram illustrating an apparatus 200 for adaptively controlling a horn volume of a vehicle according to an exemplary embodiment. According to the invention, the device comprises:
a positioning module 201, configured to obtain vehicle positioning information;
the map module 202 is used for acquiring electronic map information;
the control information module 203 is used for acquiring relevant information for controlling the volume of the vehicle horn based on the vehicle positioning information and the electronic map information;
and the determining module 204 is configured to determine the volume of the vehicle horn according to the related information for controlling the volume of the vehicle horn.
In summary, the technical scheme of the invention has at least the following beneficial effects:
the invention provides a vehicle horn volume self-adaptive control system which is based on vehicle positioning information and information acquired from an electronic map such as a navigation map under different conditions, aiming at the problem that the volume of a current vehicle horn is not adjustable. According to the relevant information (road speed limit, area attribute information, volume limiting information and the like) for controlling the volume of the vehicle horn, the vehicle horn self-adaptively emits sounds with different decibels through the preset control relation between the volume decibels and the relevant information for controlling the volume of the vehicle horn. When the vehicle is in the area with higher speed limit, the volume of the horn is correspondingly increased. When the speed limit is low (generally, the vehicle itself runs at a low speed), for example, 30km/h, the volume of the horn of the vehicle is set accordingly to a volume as small as possible. Therefore, the invention can meet the requirement of sufficient volume early warning, ensure the running safety of the vehicle, reduce the volume as much as possible and reduce the noise pollution to a certain extent. This adaptive control method both achieves the functionality of the vehicle horn and ensures that no unwanted noise is produced.
The invention does not need to use a velocimeter, a distance measuring device or an image sensor to acquire the environmental image information around the vehicle, has small computation amount of a control algorithm and high speed, and has simple and high-efficiency hardware. Furthermore, the whole process is adaptively adjusted. The user is not required to divert attention to the operation interface and input instructions. Brings convenience to users and improves the driving safety.
