Abstract

PROBLEM TO BE SOLVED: To surely detect the occurrence of an emergency situation. SOLUTION: A navigation ECU 10 collates the position of an own vehicle with map information on a navigation database 12 so as to judge whether the own vehicle is situated in a place in which a vehicle cannot pass. For example, it is judged whether the own vehicle is situated not on a road but on the surface of the water. Therefore, the occurrence of a drowning accident can be detected. In the drowning accident, there is a case in which an abnormality cannot be detected on the basis of an ordinary acceleration, a vehicle inclination state or the like. However, the drowning accident can be detected by the above judgement.

The GPS receiver 20 and the D-
A GPS receiver 22 is connected. GPS receiver 20
Detects the own vehicle position as an absolute position (latitude, longitude and altitude) by receiving a radio wave from the GPS satellite 24. Also, the D-GPS receiver 22 is a terrestrial D-GPS
The GPS error information supplied from the base station 26 is received. Therefore, the navigation ECU 10 uses the D-GPS
The current position obtained by the GPS receiver 20 is corrected based on the error information from the receiver 22, and a more accurate current position can be recognized. The position information from the GPS receiver 20 includes
Although there is usually an error of about 100 m, the D-GPS receiver 2
The current position can be detected with an error of about several meters by combining the information from Step 2. Further, the navigation ECU 10 is connected to a wheel speed sensor 30, a shift position sensor 32, and the like, and detects a traveling state of the vehicle.

Further, the navigation ECU 10 includes:
Communication devices such as a beacon communication device 40, a cellular TEL 42, and an inter-vehicle communication device 44 are connected. The beacon communication device 40 communicates with a beacon 46 provided on the roadside. The beacon 46 includes an optical beacon, a radio beacon, and the like. The beacon 46 provides absolute position information, surrounding traffic information, and receives an emergency call from the beacon communication device 40. Roadside beacon 46, police station 48, (company)
It is connected to a maintenance organization 50 for dispatch maintenance, such as the Japan Automobile Federation (JAF), a fire department 52, and an integration center 54. Therefore, when an emergency call is generated from the beacon communication device 40, this is transmitted to the police station 48, the maintenance organization 50, the fire station 52, and the integration center 54.
The integration center 54 collectively processes various types of information, and also collects information when an emergency occurs. When the destination of the drive is obtained from the vehicle, the integration center 54 also performs a service of searching for a route to the destination and providing the route to the vehicle.

The cellular TEL 42 is a vehicle-mounted mobile phone, and performs a normal telephone call via a public telephone line. And
In an emergency, police station 48, maintenance organization 50, fire station 52,
Then, an emergency call is made to the integration center 54 by telephone call. Further, the inter-vehicle communication device 44 performs various kinds of communication with the inter-vehicle communication device 56 of another vehicle, and performs an emergency call in an emergency.

An equipment control unit 60 is connected to the navigation ECU 10. This device control unit 60
Is the navigation ECU 1 when an emergency occurs.
The operation of various in-vehicle devices such as a door lock and a power window is controlled by a command from 0. Further, the backup power supply 62 is provided in the vehicle interior, and functions as a power supply only for the time required for emergency processing even in the event of a water shortage accident. The backup power supply 62 may be provided with some waterproof treatment.

The processing for a vehicle water accident in such an apparatus will be described with reference to FIG. First, it is determined whether the shift position is the P (parking) or N (neutral) position (S11). If the determination is YES, the process is terminated because the vehicle is not traveling and there is no risk of a water accident. On the other hand, if the determination in S11 is NO
If so, it is considered that the vehicle is traveling, and the current position is detected next (S12). This detection of the current position is performed based on the detection results of the GPS receiver 20 and the D-GPS receiver 22, but in consideration of the autonomous navigation based on the traveling direction, the traveling distance, the position information from the beacon 46, and the like, It is preferable to detect the position as accurately as possible.

Then, based on the current position, the surrounding map information is read from the navigation database 12 (S13), and it is determined whether or not the vehicle has fallen into the water (S1).
4). If this determination is NO, emergency processing is not required and the process ends. On the other hand, if the determination in S14 is YES, a process when an emergency occurs is performed (S15). That is, the device control unit 60 controls various devices to open windows, unlock doors, blink hazards, blow horns, and use the beacon communication device 40, the cellular TEL 42, the inter-vehicle communication device 44 to perform various operations. Make an emergency call to the emergency contact. This emergency call is based on the fact that the navigation ECU 10 automatically provides the number of the vehicle, the current position, and the like, together with information on the occurrence of a water-related accident.

In addition, since the backup power supply 62 provided in the vehicle cabin functions for at least several minutes even if the vehicle is submerged, the processing of S15 can be performed. The blinking of the hazard lamp and the horn may be performed not by the backup power supply 62 but by the power from a normal battery, or by the backup power supply 62 in response to the opening of the window, the release of the door lock, and the termination of the emergency call.

In this way, a quick and reliable emergency call can be made when a water accident has occurred. Further, since the windows are automatically opened and the doors are unlocked, safer evacuation can be performed.

Next, the determination of underwater fall in S14 will be described with reference to FIG. First, the latitude and longitude of the obtained current position are pointed on the map, and it is determined whether the point is on the sea, lake, marsh, or river (S21).
If YES in this determination, it is next determined whether the current position is a place where a vehicle such as a road, a bridge, a dike may be located (S
22). This is because there are places where the vehicle can run even on the water surface. If NO in S22, it is next determined whether or not any of the wheels other than the drive wheels is moving (S23). Underwater, the non-driving wheels do not move while the driving wheels may move. If the determination in S23 is NO, it is determined that the vehicle has fallen underwater (S24). On the other hand, NO in S21, S2
In the case of YES in 2, 23, it is determined that the vehicle does not fall underwater (S25). In this way, it can be determined whether or not the vehicle has fallen underwater.

It is also possible to determine when the vehicle enters or leaves the ferry from the route of the ferry. Further, if the position of the vehicle is measured three-dimensionally by including the altitude data in the map data, it is possible to detect that the vehicle is not on a road from the altitude data. Further, it is preferable that the detection of the occurrence of the above-mentioned water accident is comprehensively performed together with other detections. For example, the detection value of a submergence sensor may be considered together.
