Abstract

PROBLEM TO BE SOLVED: To rescue, quickly and surely, a counterpart anticipatively coming into collision, even when a great impact will not be generated in own car. SOLUTION: When a collision counterpart is a two wheeler or a smaller vehicle than own car, an information threshold is changed into a smaller value than a standard value prior to collision generation (S1, S3). Thereafter, when the actually detected acceleration/deceleration is smaller than the standard value before the change and larger than the information threshold after the change, automatic information to a prescribed contact address is performed (S4). When the information threshold is changed in a suitable execution form, the smaller the weight held by the category of the detected collision counterpart is, compared with own car, the smaller the value is set.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of a vehicle automatic notification system for automatically making a notification to a predetermined external organization when a vehicle accident or emergency occurs.

[0002]

2. Description of the Related Art Conventionally, in the field of automobiles, which is a typical vehicle, current position information is included depending on the magnitude of the detected impact (acceleration / deceleration) and the switch operation of the driver when an accident occurs or an emergency occurs. There has been proposed a vehicle automatic notification (Mayday) system that automatically makes an emergency call to a predetermined external organization by transmitting a rescue signal from the own vehicle.

[0003]

According to the above-mentioned conventional vehicle automatic notification system, the driver can reliably make an emergency notification without being forced to make a complicated judgment in an emergency, which is convenient. Is high.

However, the traveling environment of an automobile changes variously, and there are various opponents who are expected to collide with their own vehicle while traveling or who actually collide when an accident occurs. For this reason, in the above-described vehicle automatic notification system, even if automatic notification is not performed depending on the magnitude of the acceleration / deceleration generated in the vehicle, depending on the situation of the other party, rescue may be necessary. .

Further, conventionally, in the field of automobiles, in order to prevent the own vehicle from falling into a dangerous traveling state, a driving support system which automatically outputs an alarm for avoiding a danger and an avoidance operation is provided. In this system, in order to determine the alarm output and the control state of the avoidance action, this system is based on various information and captured images acquired from equipment installed on the road side The presence of an object is detected.

The above-mentioned systems have been studied so far with independent configurations on vehicles, but in vehicles equipped with these systems, each system provides information necessary for processing. Since the information is collected and detected, it is considered possible to optimize the automatic notification in the vehicle automatic notification system described above by using the driving support system.

[0007] Therefore, an object of the present invention is to provide an automatic notification device for a vehicle, which can quickly and surely rescue a partner who is expected to have a collision even if a large impact does not occur on the vehicle. .

[0008]

In order to achieve the above object, the vehicular automatic notification device according to the present invention is characterized by the following configurations.

That is, there is provided a vehicular automatic notification device comprising a control means for automatically making a notification to a predetermined contact address when an acceleration / deceleration larger than a predetermined threshold value is detected. An automatic notification device for a vehicle, which makes a notification automatically to the predetermined contact according to a predicted collision partner even when the detected acceleration / deceleration is smaller than the threshold value.

In a preferred embodiment, the control means causes an impact when the predicted collision partner is a motorcycle or a vehicle smaller than the own vehicle, as in the first embodiment (FIG. 3) described later. If the acceleration / deceleration that is actually detected is smaller than the threshold value before the change and larger than the threshold value after the change by changing the predetermined threshold value to a small value prior to In addition, it is preferable that the predetermined contact is automatically notified.

Further, for example, the control means, when the acceleration / deceleration larger than the changed threshold value is detected, as in a second embodiment (FIG. 4) described later, sends the predetermined contact information. It is preferable to include information providing means for urging an occupant of the own vehicle to confirm the state of the collision prediction partner prior to the automatic notification of.

In this case, more preferably, for example, as in a second embodiment (FIG. 4) described later, the information providing means determines whether or not the automatic notification to the predetermined contact is necessary. It is preferable that the vehicle includes a selection unit that can be selected by the passenger.

Further, for example, when the acceleration / deceleration greater than the changed threshold is detected, the control means sends the message to the predetermined contact as in the third embodiment (FIG. 5) described later. Prior to the automatic notification of the above, regarding the contents of action for the occupant of the own vehicle to confirm the state of the expected collision partner with respect to the portable terminal separate from the automatic notification device for vehicle. It is preferable to include information providing means for providing information.

In this case, more preferably, for example, as in a third embodiment (FIG. 5) described later, the information providing means automatically responds to the predetermined contact point according to the operation on the portable terminal. It is good to support the report.

Further, for example, the control means is, for example, as in a fourth embodiment (FIG. 6) described later, the control means is
Even when an acceleration / deceleration smaller than the threshold after the change is detected, the collision prediction opponent is a two-wheeled vehicle,
When a collision avoidance operation targeting the two-wheeled vehicle is detected in the own vehicle, it is preferable to include information providing means for urging an occupant of the own vehicle to check the state of the two-wheeled vehicle.

[0016]

As described above, according to the present invention, there is provided an automatic notification device for a vehicle capable of promptly and surely assisting an opponent who is expected to have a collision even when a large impact does not occur on the vehicle. Offer is realized.

That is, according to the first aspect of the present invention, when the anticipating collision partner is, for example, a motorcycle or a vehicle smaller than the own vehicle, the threshold value becomes a small value before the impact occurs. Since it is changed, even if the actually detected acceleration / deceleration is smaller than a predetermined threshold value (reference value) at which automatic notification is originally made, automatic notification can be performed (claim 2), Regardless of whether or not a collision with the predicted collision opponent has actually occurred, the predicted collision opponent can be promptly and reliably rescued even when the occupant of the vehicle is agitated.

According to the third aspect of the present invention, the action to be taken by the occupant is notified to the occupant by the guidance or the like. And it can certainly be rescued.

Further, according to the invention of claim 4, since the occupant of the vehicle can select whether or not the automatic notification is necessary, even if the acceleration / deceleration greater than the changed threshold value is detected, the collision occurs. It is possible to prevent an automatic notification from being made to a predetermined contact even though there is no abnormality in each other when a collision between the expected opponent and the own vehicle is avoided.

Further, according to the invention of claim 5, after the acceleration / deceleration greater than the threshold value after the change is detected, for example, a swaying occupant exits the vehicle in an attempt to rescue the expected opponent. In this case, a specific action to be taken by the occupant is notified from the mobile terminal, so that it is possible to quickly and surely rescue the collision prediction partner.

Further, according to the invention of claim 6, the occupant outside the vehicle can make a notification to a predetermined contact by operating the portable terminal without returning to the own vehicle. Even in the case of collision, it is possible to quickly and surely rescue the anticipating collision partner.

Further, it is generally known that a two-wheeled vehicle is less stable than a four-wheeled vehicle, so that an occupant is seriously damaged when an accident occurs. However, according to the invention of claim 7, , Even if an acceleration / deceleration smaller than the changed threshold value is detected, the motorcycle and its occupants who are the collision prediction opponent are irrespective of whether or not a collision with the collision prediction opponent actually occurs. Since the occupant is informed of the action to be taken in order to rescue the above condition by the guidance or the like, even if the occupant of the own vehicle is agitated, it is possible to quickly and reliably rescue the collision prediction partner.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of an automatic notification system for a vehicle according to the present invention will be described below in detail with reference to the drawings.

[First Embodiment] FIG. 1 is a block diagram showing the system configuration of an automatic vehicle alarm system according to the first embodiment.

In FIG. 1, a control unit 11 is a general electronic control unit equipped with a CPU, a memory, an input / output interface, etc., which are not shown, and detects the traveling state of the own vehicle and road facilities (so-called, In accordance with various information received from the infrastructure side, AHS (Advanced Cruise-assist H) that outputs a warning to the driver (passenger) and controls driving assistance operations (including automatic driving) for risk avoidance
function system and automatic notification that automatically sends out a specified rescue signal when the magnitude of the detected impact is larger than a specified threshold value or when the occupant operates the emergency operation switch. It is a control unit having a (Mayday) control function.

That is, in the control unit 11, the vehicle speed detected by the vehicle speed sensor 12, information received by the road-vehicle communication device 15 via the AHS on-vehicle antenna 16, and the acceleration / deceleration detected by the acceleration (G) sensor 14. The speed etc. is input.

Here, a signal to be received using the AHS on-vehicle antenna 16 is transmitted by the AHS base station 103 via a roadside antenna 104 (corresponding to a base point antenna 21 and an information providing antenna 22 shown in FIG. 2 which will be described later). Sent out.

Then, the control unit 11 issues a warning (alarm output) to the driver using the display 19 and / or the speaker 20 based on the inputted information, and also operates the driver to avoid danger. In order to provide assistance, automatic transmissions, brakes,
By appropriately controlling the throttle opening and the like, automatic driving of the own vehicle or driving operation support (intervention of driving operation by the driver) is performed.

Since the control processing itself performed by the control unit 11 for avoiding danger is not the essence of the present application, detailed description thereof will be omitted.

Further, the control unit 11 controls the acceleration (G)
When the magnitude of the impact (acceleration / deceleration) detected by the sensor 14 is larger than a predetermined threshold value, or the occupant operates the emergency operation switch (automatic notification selection switch) 17
When is operated, by controlling the operation of a separate communication device (for example, a mobile phone) that is integral with or detachable from the control unit, the automatic notification vehicle-mounted antenna 18
Send a predetermined relief signal. In a preferred embodiment,
The rescue signal includes current position information detected by a GPS (Global Positioning System) sensor.

The rescue signal transmitted from the on-vehicle antenna 18 for automatic notification is received by the automatic notification base station 101 via the roadside antenna 102.

As described above, the control unit 11 executes a general AHS function for avoiding a danger while the vehicle is running, and a feature of this embodiment is that the AHS function causes a collision with the vehicle. The opponent who was judged to be expected (collision expected opponent: hereinafter abbreviated as collision opponent)
The optimum Mayday control function is executed according to

In the present embodiment, among the Mayday control functions, the control function itself which automatically sends a predetermined rescue signal when an acceleration / deceleration greater than a set threshold value is detected is Since a general method can be adopted and is not the essence of the present application, detailed description will be omitted.

FIG. 2 is a diagram for explaining the outline of the AHS in the vicinity of the intersection, which is applicable in the first embodiment.

In the figure, the vehicle detection sensor 23 is installed on the road to detect the position, vehicle speed, type, etc. of the oncoming vehicle 2. The information detected by the vehicle detection sensor 23 is transmitted to the information providing antenna 22 via the AHS base station 103.

The base point antenna 21 is installed on the road to provide the starting position of the section for providing AHS information to the passing vehicle (in this case, the own vehicle 1). The information providing antenna 22 provides the own vehicle 1 with information about the oncoming vehicle (other vehicle) 2 traveling straight ahead (types of ordinary vehicles, large vehicles, etc.), road shape (distance to intersection, lane width, etc.). Installed on the road to serve.

The control unit 11 mounted on the vehicle 1 is
By using the road-to-vehicle communication device 15 to communicate with the base point antenna 21 installed at a predetermined position in front of the intersection existing ahead, the passage timing at the predetermined position can be detected. Then, the control unit 11 can detect the relative positional relationship between the base point antenna 21 and the host vehicle 1 based on the detected passage timing and the vehicle speed pulse value output from the vehicle speed sensor 12.

Further, since the control unit 11 can obtain the distance from the information providing antenna 22 to the intersection by using the road-vehicle communication device 15, the relative positional relationship between the detected base point antenna 21 and the own vehicle 1 is obtained. By comparing with, it is possible to determine whether or not the host vehicle 1 is present within the intersection.

Further, since the control unit 11 can obtain the position and the vehicle speed of the oncoming vehicle 2 from the information providing antenna 22 by using the road-vehicle communication device 15, whether or not the oncoming vehicle 2 exists in the intersection. You can also judge.

Further, the control unit 11 can obtain the vehicle type (large vehicle, ordinary vehicle, motorcycle, etc.) or the length of the oncoming vehicle 2 from the information providing antenna 22 by using the road-vehicle communication device 15.

FIG. 3 is a flowchart showing a control process performed by the control unit 11 in the first embodiment, and a CPU (not shown) provided in the control unit 11 is shown.
Represents a processing procedure executed by.

In the figure, step S1: FIG.
As shown in FIG. 2, from the base point antenna 21 and the information providing antenna 22 provided on the road side, the road-to-vehicle communication device 15 is used to obtain at least information regarding the type or length of another vehicle in front of the own vehicle. In addition to acquiring the information, when it is determined that the other vehicle is a collision partner (collision expected partner), it is determined whether the collision partner is a motorcycle or a vehicle smaller than the own vehicle.

Here, when the information about the length, not the type of the collision partner, is acquired from the outside, it is necessary to determine the type of the collision partner based on the information. In that case, for example, Vehicles with a total length of less than 2 m are two-wheeled vehicles, vehicles with a total length of 2 m or more and less than 3.5 m are light vehicles, and the total length is 3.
A vehicle type determination map for each vehicle length such as a vehicle having a length of 5 m or more and less than 5 m is a normal vehicle, and a vehicle having a total length of 5 m or more is a large vehicle is stored in the control unit 11 in advance, and the map is collided. It may be referred to in step S1 according to the length of the partner.

Since a general method can be adopted as a method for determining whether or not another vehicle in front of the own vehicle is a collision partner, a detailed description of this embodiment will be omitted.

Step S2: If it is determined in step S1 that the collision partner is neither a two-wheeled vehicle nor a vehicle smaller than the own vehicle, in this step, the notification threshold value is set to a normal reference value.

Step S3: If it is determined in step S1 that the collision partner is a two-wheeled vehicle or a vehicle smaller than the own vehicle, in this step, the notification threshold is set to
Change to a value smaller than the above reference value. In general, the energy generated during a collision increases as the mass of the colliding object increases, so when changing the notification threshold, the smaller the weight of the detected collision partner than the own vehicle, the smaller the value. Should be set.

Step S4: The notification threshold value set in step S2 or step S3 and the acceleration sensor 1
Ma based on the impact (acceleration / deceleration) detected by No. 4
Perform yday control. That is, when the magnitude of the detected impact is larger than the currently set threshold for notification, automatic notification is given to a predetermined contact, and step S
Return to 1.

As described above, in this embodiment, when the collision partner is a motorcycle or a vehicle smaller than the own vehicle, the notification threshold value is changed to a value smaller than the reference value before the impact occurs. After that, if the actually detected acceleration / deceleration is smaller than the reference value before the change and larger than the notification threshold value after the change, the predetermined value is determined regardless of whether the collision actually occurred. Automatically notify the contact. As a result, even when the occupant of the own vehicle is agitated, it is possible to quickly and surely rescue the two-wheeled vehicle or the vehicle smaller than the own vehicle, which is a collision partner, and the occupant thereof.

[Second Embodiment] Next, a second embodiment based on the vehicle automatic notification device according to the first embodiment will be described. Further, in the present embodiment, when the collision partner is a motorcycle or a vehicle smaller than the own vehicle, when a acceleration / deceleration larger than the changed threshold value (a value smaller than the reference value) is detected, the predetermined contact information is given. Prior to the automatic notification to the passengers, the occupants of the vehicle can check the condition of the collision partner (motorcycle or a vehicle smaller than the vehicle and its occupants) and rescue them if necessary. The point of providing guidance is different from that of the first embodiment.

FIG. 4 is a flow chart showing a control process performed by the control unit 11 in the second embodiment, and a CPU (not shown) provided in the control unit 11 is provided.
Represents a processing procedure executed by.

Steps S11 to S shown in FIG.
In each step of 13, the same processing as that of FIG. 3 in the first embodiment is performed.

Step S14: It is judged whether or not the currently set threshold value for notification is larger than the impact (acceleration / deceleration) detected by the acceleration sensor 14, and the detected impact value is higher than the notification threshold value. If small, step S1
If the detected impact is larger than the notification threshold, the process returns to step S15.

Step S15: Whether the currently set notification threshold value is the normal reference value set in step S12 or a value smaller than the reference value set in step S13. If it is determined that the reference value is present, the process proceeds to step S18, and if it is smaller than the reference value, the process proceeds to step S16.

Step S16: Since the detected impact is larger than the notification threshold value corresponding to the collision partner, the collision partner is also expected to be damaged. Therefore, in this step, using the display 19 and / or the speaker 20, the occupant of the own vehicle can easily check the state of the vehicle of the collision partner and the occupant, and can easily rescue the occupant, if necessary. Inform the guidance. At this time, the guidance to be notified to the occupants of the vehicle is
For example, "stop your vehicle in a place that does not interfere with traffic,
Check the current situation of the motorcycle or other vehicle that was expected to collide. "If you can confirm the situation, carry out rescue activities as necessary, and return to your vehicle and operate the automatic notification selection switch." In this case, when the guidance is displayed on the display 19 having the touch panel function, the operation area of the automatic notification selection switch 17 may be highlighted together with the guidance.

Step S17: Automatic report selection switch 1
It is determined whether or not 7 is operated by the occupant. If the switch is operated, the process proceeds to step S18, and if not, the process returns to step S1.

Step S18: The impact (acceleration / deceleration) detected by the acceleration sensor 14 is larger than the currently set notification threshold value, or the operation of the automatic notification selection switch 17 is detected in Step S17. In this step, automatic notification is given to a predetermined contact, and the process returns to step S1.

In the present embodiment as described above, when the collision partner is a motorcycle or a vehicle smaller than the own vehicle, the notification threshold value is changed to a value smaller than the reference value before the impact occurs. After that, if the actually detected acceleration / deceleration is smaller than the reference value before the change and larger than the changed notification threshold value, the state of the collision partner is determined regardless of whether the collision actually occurred. Instead, guidance is provided to encourage passengers in the vehicle to check. As a result, even when the occupant of the own vehicle is agitated, it is possible to quickly and surely rescue the predicted collision opponent.

Further, since the occupant of the vehicle can select the necessity of the automatic notification by the automatic notification selection switch 17, even if the acceleration / deceleration larger than the changed threshold value is detected, the collision prediction partner When the collision with the own vehicle is avoided, it is possible to prevent the automatic notification from being made to the predetermined contact even though there is no abnormality in each other.

[Third Embodiment] Next, a third embodiment based on the vehicular automatic notification device according to the first and second embodiments described above will be described. In this embodiment, guidance is provided as in the second embodiment, and further,
The second embodiment is different from the second embodiment in that information can be provided to a mobile terminal carried by an occupant and automatic notification can be made according to the operation of the mobile terminal.

FIG. 5 is a flow chart showing the control processing performed by the control unit 11 in the third embodiment, and a CPU (not shown) provided in the control unit 11 is shown.
Represents a processing procedure executed by.

Steps S11 to S shown in FIG.
In each step of 18, the same processing as that of FIG. 4 in the second embodiment is performed.

Step S19: When the operation of the automatic notification selection switch 17 is not detected in step S17, in this step, the portable terminal (so-called PDA, mobile phone, etc.) carried by the passenger is sent to the passenger in step S16. In accordance with the guidance given in this section, we will provide information on the content of actions for confirming the state of the other party of the collision and support automatic notification to a predetermined contact. In this case, the mobile terminal carried by the occupant and the control unit 11 are registered in advance with each other, and for example, wireless communication based on a short-range wireless communication system such as Bluetooth or communication using a public wireless telephone line is possible. Configuration, support for automated notifications is provided by the designated contact or other emergency contact (medical facility,
Provision of telephone numbers of police stations, fire departments, etc., and mediation function of control unit 11 for contact with predetermined contact points in response to simple operations (for example, operation of function keys or instructions by voice input) on the information terminal. Etc. are assumed.

In the present embodiment, in addition to the processing in the second embodiment, when the occupant does not operate the automatic notification selection switch 17, the occupant of the own vehicle has a portable terminal. Then, guidance for confirming the state of the collision partner is provided. This gives, for example,
When a disturbed occupant tries to rescue a collision partner and goes out of the vehicle, a specific action to be taken is notified from the mobile terminal, so that the collision partner can be rescued quickly and reliably.

Further, due to the function of supporting the automatic notification in the mobile terminal, the occupant who gets out of the vehicle can directly report the notification to a predetermined contact point by operating the mobile terminal without returning to the own vehicle. Or the control unit 11
Since it can be easily performed via the vehicle, for example, even when the occupant is agitated, it is possible to quickly and reliably rescue the collision partner.

[Fourth Embodiment] Next, a fourth embodiment based on the vehicular automatic notification device according to the first and second embodiments described above will be described. The present embodiment has a guidance providing function and a function that allows an occupant to select the necessity of automatic notification as in the second embodiment. However, when the collision partner is a two-wheeled vehicle, the changed threshold is used. The second point is that even if an acceleration / deceleration smaller than the value (a value smaller than the reference value) is detected, the function of providing the guidance and the function of enabling the occupant to select the necessity of the automatic notification are second. Different from the embodiment.

FIG. 6 is a flow chart showing a control process performed by the control unit 11 in the fourth embodiment, and a CPU (not shown) provided in the control unit 11 is shown.
Represents a processing procedure executed by.

Steps S11 to S shown in FIG.
In each step of 18, the same processing as that of FIG. 4 in the second embodiment is performed.

Step S21: Since it is determined in step S14 that the impact (acceleration / deceleration) detected by the acceleration sensor 14 is smaller than the currently set notification threshold value, in this step, control as AHS is performed. When the output is performed, the operation control of the brake, the steering, and the like is performed, and it is determined whether the behavior of the own vehicle has changed as the collision avoidance operation. Whether or not the control output as the AHS is performed is determined by an automatic driving operation for avoiding a collision with another vehicle currently set as a collision partner in a general control process separately performed as an AHS function. Alternatively, it may be determined whether or not the driving support operation (intervention of the driving operation by the driver) has been performed or is being performed. Then, if it is determined that the control output as the AHS is performed, the process proceeds to step S22, and if not, the process returns to step S11.

Step S22: AH at step S21
Since it is determined that the control output as S has been performed, in this step, it is determined whether the type of the collision opponent determined in step S11 is a two-wheeled vehicle. When the collision partner is a two-wheeled vehicle, it is generally less stable than a four-wheeled vehicle, so some damage may occur. Therefore, even if the acceleration / deceleration detected by the acceleration sensor 14 in the current control cycle is smaller than the notification threshold set to a small value in step S13,
When it is determined in this step that the collision partner is a two-wheeled vehicle, the process proceeds to steps S16 and S17, where guidance is provided and it is possible for the occupant to select whether or not automatic notification is necessary. On the other hand, when it is determined in this step that the collision partner is a vehicle other than the two-wheeled vehicle, the process returns to step S11.

As described above, in the present embodiment, even when an acceleration / deceleration smaller than the changed value is detected in the state where the notification threshold is changed to a value smaller than the reference value, When the collision partner is a two-wheeled vehicle and the control output as the AHS targeting the two-wheeled vehicle is detected in the own vehicle, the state of the two-wheeled vehicle is checked regardless of whether or not the collision actually occurred. Guidance is provided for the vehicle occupant to confirm, and the occupant can select the necessity of automatic notification. As a result, even if the occupant of the vehicle is agitated, the collision partner can be rescued quickly and reliably.

According to each of the embodiments that have died, it is possible to quickly and reliably rescue the opponent who is expected to collide even if a large impact does not occur on the vehicle.

In each of the above-described embodiments, the case where the AHS for acquiring various information from the equipment provided on the road side by communication is adopted as the driving support control of the driver has been described. It is not limited, but the CCD (Charge Coupled Devic) installed in the vehicle
Autonomous ASV (Advanced) that detects the presence and position of obstacles, lane departure of the vehicle, its angle, etc. by capturing the surrounding image with an imaging device such as e) and performing image processing on the captured image. It can also be realized by adopting a Safety Vehicle system.

Further, in each of the above-described embodiments, the device configuration is such that the control function for AHS and the automatic notification control function are executed in the single control unit 11, but the present invention is not limited to this. Instead, a control unit for AHS control and a control unit for Mayday control may be individually mounted on the vehicle, and information may be appropriately transmitted and received between the control units.
