Description

The present invention relates to an in-vehicle abnormality notification device for informing an abnormality in a vehicle.

In vehicles, there is a concern that an accident may occur that causes infants and children to suffer severe symptoms such as heat stroke and hypothermia.
Therefore, in an emergency, as a part of the rescue of the occupants in the vehicle, when it is detected that the heat stroke is highly likely to occur from the environment inside the vehicle as disclosed in Patent Document 1, the navigation of the vehicle is detected. Techniques have been proposed for displaying such a fact on the display of the device or for notifying the passenger by voice.

JP, 2007-76589, A

Incidentally, the occurrence of heat stroke in infants and children often occurs when the infants and children are left behind in the passenger compartment of the parked vehicle.
In the event of an emergency in which an infant or child is left behind in such a parked vehicle, in most cases, there is no passenger in the vehicle compartment other than the infant or child who has developed a serious symptom.
In such cases, it is effective to seek help from people around the parked vehicle.

However, with the technique of the cited document 1, although the emergency notification can be delivered to the vehicle interior, it is difficult to deliver the notification to a third person outside the vehicle, for example, a person (for example, a passerby) around the vehicle.
Therefore, an object of the present invention is to provide an abnormality in a vehicle in a vehicle that can sufficiently inform a person around the vehicle that a serious person is present when a passenger left behind in the vehicle develops a serious symptom when the vehicle is parked. An informing device is provided.

Aspects of the present invention include a physical condition detection unit that detects a physical condition of an occupant left in a passenger compartment of a parked vehicle, a physical condition determination unit that determines whether the physical condition of the occupant is serious, and a physical condition of the occupant. When it is determined that the condition is serious, a display unit that displays information indicating that a serious occupant is present on the outer surface of the vehicle in order to inform a person outside the vehicle that the occupant is serious. It is assumed to have.

According to the present invention, in a parked vehicle, when the occupant left behind in the vehicle (for example, a dwarf) feels unwell and develops to a serious symptom (emergency), a serious problem occurs on the outer surface of the vehicle. The fact that there is a passenger is displayed.
Therefore, when the occupant develops a serious symptom during parking, the display can sufficiently inform the people around the vehicle that there is a serious person, and ask the person who is outside the vehicle directly for rescue. You can

Therefore, a person outside the vehicle can promptly assist a serious occupant in the vehicle compartment by discovering the display of the vehicle and notifying a predetermined facility such as an emergency facility.

The top view showing "there is a serious person" displayed on the outer surface of the vehicle body. The flowchart which shows the control of the same display. The figure which shows the structure of the vehicle interior abnormality notification apparatus which becomes the aspect which concerns on the 2nd Embodiment of this invention. FIG. 3 is a plan view of the vehicle illustrating the installation of the camera around the vehicle and the motion sensor. The figure which shows the display condition at the time of parallel parking. The figure which shows the display condition at the time of parallel parking.

Hereinafter, the present invention will be described based on the first embodiment shown in FIGS. 1 to 3.
Reference numeral 1 in FIG. 1A indicates a vehicle body of the vehicle X. The vehicle interior 1 a of the vehicle body 1 has a front seat 3 and a rear seat 5. A front door 7 and a rear door 9 are provided on both sides of the vehicle body 1 facing the seats 3 and 5, respectively. Each door 7, 9 has an automatic door lock device 11 built-in (shown in FIG. 1B), and can be locked/unlocked by remote control. Incidentally, although not shown, the vehicle X is provided with an IG switch, a selector lever, etc., which are necessary for traveling the vehicle.

The in-vehicle abnormality notification device 13 is assembled to the vehicle X.
As the in-vehicle abnormality notification device 13 here, when the occupant A who has developed heat stroke, which is one of the serious symptoms, is left behind in the vehicle interior 1a (emergency), the fact is notified to the person outside the vehicle. A device for notifying is given as an example. In this case, a serious occupant A is often left behind on the rear seat 5, and therefore, a case where the occupant A seated on the rear seat 5 has a serious symptom, for example, heat stroke will be described as an example.

As shown in FIG. 1B, in the configuration of the in-vehicle abnormality notification device 13, for example, a control unit 17 (ECU) having a physical condition determination unit 15 that determines the physical condition of the occupant A is used. A configuration in which the door lock device 11, the vehicle exterior environment detection unit 18, the physical condition detection unit 19, the projection device 23 as a display unit, and the like are connected is used.
Of these, the vehicle exterior environment detection unit 18 detects, for example, the heat index outside the vehicle interior 1a. The heat index is an index obtained by detecting temperature, humidity and sunlight.

The physical condition detecting unit 19 includes an infrared type body temperature sensor 21a for detecting the body temperature of the occupant A seated on the rear seat 5 as shown in FIG. 1A, and the occupant A seated on the rear seat 5 as well. A configuration in which a reflective pulse wave sensor 21b that detects a heart rate is combined is used. That is, the physical condition of the occupant A (the occupant seated on the rear seat 5) in the passenger compartment 1a is detected from the body temperature and the heart rate. Incidentally, the infrared type body temperature sensor 21a and the reflection type pulse wave sensor 21b are provided here, for example, on the inner surface of each rear door 9, and the physical condition change of the occupant A seated on the rear seat 5 is detected from a position away from the occupant. Of course, other methods may be used.

The physical condition determination unit 15 provided in the control unit 17 detects that the IG switch of the vehicle X is off, the selector lever is in the P range, and the door lock is opened or closed, that is, when the occupant is left behind in the parked vehicle. The physical condition of the occupant A is determined based on the information from the vehicle exterior environment detection unit 18 and the physical condition detection unit 19. As a determination method, for example, whether or not the environment is prone to heat stroke is detected from the heat index. Based on the changes in the body temperature and heart rate of the occupant A under the environment where the heat stroke is likely to occur, it is determined whether the occupant A has developed a serious symptom, here, heat stroke. Of course, other determination methods may be used. When it is determined that heat stroke has developed, the control unit 17 operates the projection device 23.

The projection device 23 is provided, for example, in the center of the ceiling in the vehicle interior 1a as shown in FIGS. The projection device 23 indicates, for example, for all the wind surfaces of the vehicle X, information indicating that a serious occupant is present in the passenger compartment 1a, specifically, the occupant A having a heat stroke here. It has a projection unit that projects information, for example, the phrase "SOS is seriously ill".
That is, when it is determined that the occupant left behind in the passenger compartment 1a has developed heat stroke, the projection device 23 operates according to a command from the control unit 17 to operate all windows of the vehicle X as shown in FIG. Surface, that is, the entire front window surface 26 of the vehicle X, the entire rear window surface 27, the entire front window surface 7a (side window surface), and the entire rear door 9 window surface 9a (side window surface), The wording information that "there is a seriously occupant", which is information that the heat stroke person is in the vehicle interior 1a, is displayed.

Of course, by using the physical condition detection of the occupant A by the physical condition detection unit 19, even if the position information suggesting the seat position where the heatstroke person is seated, for example, "there is a serious person in the rear seat" is displayed. Good.
Obviously, the projection display uses colors and designs that stand out so that people around the vehicle can easily notice the display.

It should be noted that the control unit 17 is provided with a function for unlocking the door lock device 11 of each of the doors 7 and 9 when it is determined that the occupant A has a serious symptom, that is, a heat stroke person. It makes it easier for people with heat stroke who are left behind in 1a.
Next, the operation of the in-vehicle abnormality notification device 13 will be described with reference to the flowchart shown in FIG.

Now, for example, it is assumed that the vehicle X is parked in the parking lot in the summer. At this time, the driver of the vehicle X stops the vehicle X in the parking space, then turns off the IG switch as in step S1 and operates the selector lever to the "P range" (parking).
At this time, for example, it is assumed that the driver goes out from the vehicle interior 1a and goes out while leaving an occupant A, for example, a child (one child) sitting on the rear seat 5. In order to make it easier to recognize the situation, from now on, the occupant A will be called the child A.

Here, for example, it is assumed that the temperature outside the vehicle is 30° C. or higher (high temperature), and the heat index is an index at which heat stroke easily occurs, for example, 25° C. or higher, which is a high temperature.
The physical condition detection unit 19 detects the physical condition of the child A left in the vehicle interior 1a under the same environment as shown in step S3. Specifically, the infrared type body temperature sensor 21a and the reflection type pulse wave sensor 21b on the inner surface of the rear door 9 detect the body temperature and the heart rate of the child A sitting on the rear seat 5.

When the remaining time elapses, the temperature inside the vehicle interior 1a rises, and the body of the child A is affected by the heat and the body temperature and the heart rate rise rapidly.
When the body temperature and the heart rate under the high temperature environment increase until they correspond to heat stroke, the physical condition determination unit 15 determines that the child A has become a serious symptom, heat stroke, as shown in step S5. ..

Then, the projection device 23 directs from the respective projection units according to the same determination to the respective wind surfaces of the vehicle X, that is, the front wind surface 26, the rear wind surface 27, the front door 7 wind surface 7a, and the rear door 9 wind surface 9a. As shown in FIG. 2, information indicating that a serious person is present, that is, a heat stroke person is left behind in the vehicle interior 1a is projected.
By the projection display performed on the entire window surface, people around the parked vehicle are informed that the child A with heat stroke is in the vehicle compartment 1a.

In addition, the front door 7 and the rear door 9 that have been locked are unlocked in accordance with the determination of heat stroke, and the child A is easily rescued.
As described above, when the child A left in the vehicle interior 1a develops a serious symptom (here, heat stroke) during parking, a person around the vehicle is indicated by the display on the outer surface (wind surface) of the vehicle. [Not shown], it is possible to inform that there is a seriously ill person (person with heat stroke), and it is possible to directly ask a person outside the vehicle for rescue.

Therefore, a person outside the vehicle can promptly help the child A (serious occupant) in the vehicle interior 1a by finding the display of the vehicle X and notifying a predetermined facility such as an emergency facility.
In particular, the display on the wind surface of the vehicle X is displayed at a position where a person outside the vehicle (third party) can easily see it, so that a person outside the vehicle can easily notice. Moreover, since the doors 7 and 9 are unlocked according to the seriousness, the rescue operation of the child A becomes easy.

Moreover, since it is determined whether or not the physical condition of the child A is serious based on the changes in the body temperature and the heart rate of the child A, a simple method is required.
4 to 7 show a second embodiment of the present invention.
The present embodiment does not display the information indicating that "there is seriousness" on the entire surface in the front-rear direction and the left-right direction of the vehicle X as in the first embodiment, but faces the traffic area where a person of the parked vehicle passes. Only the side displays the information that "there is seriousness". In particular, the present embodiment also displays whether the serious person is an adult or a dwarf, and where the serious person is.

Specifically, as for the method of displaying only on the side facing the traffic area where people pass, for example, as shown in FIG. A peripheral camera 31 (corresponding to the image pickup section) is provided. In addition, the control unit 17 includes a traffic area determination unit 33 that determines whether or not there is a traffic area through which a person passes around the area facing the parked vehicle, based on each imaged information around the vehicle captured by the vehicle outside camera 31. Set up. When the child A, who is left behind in the passenger compartment 1a, develops heat stroke, the projection device 23 displays only "a serious person is in the passenger compartment 1a" only on the wind surface facing the traffic area where people around the vehicle pass. Information is displayed.

As a result, when the child A left behind in the vehicle compartment 1a develops heat stroke, for example, in the case of parallel parking at the back in parallel parking spaces α in the parking lot of the facility as shown in FIG. In front of the parking space α, there is a passing space β through which a person γ who is a passing area can pass, so only the wind surface facing the passing space β, here, the front wind surface 26, is a serious person. Information that there is a person with heat stroke is projected and displayed.

Further, as shown in FIG. 7, for example, when parallel parking is performed in the parking space δ on the side of the sidewalk T of the road S, when the child A left in the vehicle compartment 1a develops heat stroke (emergency), parking is performed. On the left side of the vehicle, there is a sidewalk T, which is a traffic area, so only the window face facing the sidewalk T, here, the wind face 7a of the door 7 of the front door 7 and the wind face 9a of the rear door 9 located on the left side here. In addition, it is projected and displayed that there is a heatstroke person who is a serious person.

As described above, even if the "display of a seriously ill person (person with heat stroke)" is performed mainly on the person S passing through the traffic area in order to ask the people around the vehicle for rescue, the first implementation The same operational effect as the form is achieved.
Not limited to this, as shown in FIG. 4 (dashed line) and FIG. 5, a human sensor 37 (one point) for detecting a person γ (passerby) approaching the parked vehicle is provided at each of front, rear, left and right parts of the vehicle body 1. When the human sensor 37 detects a person γ approaching the parked vehicle, a window surface facing the traffic area such as the traffic space β and the sidewalk T, here, the window of the front door 7 and the rear door 9 is provided. You may display on the surface 7a, 9a that a serious person exists. Of course, the human sensor 37 may be used in the first embodiment as well.

When the display is performed using the human sensor 37 in this way, information is easily transmitted to passersby.
Also, regarding the display of the seriously ill (heat stroke), the display is made to make it easier to recognize the situation.
For example, as shown in FIG. 5, an in-vehicle camera 41 that takes an image of the rear seat 5 side is provided in the vehicle interior 1a. The control unit 17 is provided with a seat determination unit 43 that determines a seat position where a serious occupant is seated from the captured image information, and a small/adult determination unit 45 that determines whether the serious occupant is a dwarf or an adult. Be done. Thereby, it is determined that a serious occupant is seated on the rear seat 5 (here, the front or rear seat), and that the serious occupant is an infant or a child (children). Equivalent to detection means, judgment function).

For example, in addition to the wording information "there is a serious person" in the projection device 23, the "rear seat" that indicates where the serious person is as shown in FIG. 6 and the rear seat position as shown in FIG. Positional information such as an "arrow symbol" indicating "," and occupant information "dwarf" indicating that the seriously ill child is present are set. Of course, although not shown, the occupant information "adult" is also set.
As a result, when the serious person is a child and is seated on the rear seat 5, not only the display content that only the serious person is present as in the first embodiment but also the detailed content is displayed, for example, as shown in FIG. Each window has a "serious person in the back seat (children)" as shown in Fig. 7 and a "serious person in the back seat in the direction of the arrow (children)" as shown in Fig. 7. Is displayed on the surface.

In this way, by displaying the status of the seriously ill, it is possible to promptly respond to the rescue of the seriously ill (heat stroke).
However, in the second embodiment, the same parts as those in the first embodiment are designated by the same reference numerals and the description thereof is omitted.
It should be noted that the present invention is not limited to the above-described embodiment, and various modifications may be made without departing from the spirit of the present invention. For example, in the above-described embodiment, the heat stroke that develops in the heat is given as an example of any serious symptom, but the present invention is not limited to this, and may be the case of hypothermia that develops in the cold such as winter. The point is to notify people around the vehicle that there is an occupant who has developed a serious symptom.

Further, in the above-described embodiment, the projection device is used as the display unit. However, the present invention is not limited to this, and a color liquid crystal display film may be used, that is, any device capable of displaying on the outer surface of the vehicle may be used. Of course, the child is taken as an example of the occupant left behind in the vehicle, but it is needless to say that the occupant may be an adult.
