The management station 3 retrieves the current position of the vehicle 1 from the map database 82 based on the position information data transmitted from the on-board equipment of the vehicle 1 and superimposes it on a map. Analyze the abnormal signal transmitted from the in-vehicle device, determine what the abnormal signal indicates, determine the degree of abnormality caused by the abnormal signal, and determine the level of abnormality indicated by the abnormal signal. The degree is analyzed, and a message (instructing the current state of the vehicle 1 and what to do) is output from the CPU 80 using the antenna 86 according to the degree of abnormality. At this time, based on the map data retrieved from the map database 82, the optimum repair shop located at the shortest distance of the vehicle 1 is displayed, and the repair shop information is transmitted to the on-vehicle equipment of the vehicle 1.

The operation of the vehicle-mounted equipment of the vehicle 1 will be described with reference to the operation flowchart of FIG. 6, and the operation of the management station 3 will be described with reference to the operation flowchart of FIG. In this operation flowchart. A temperature sensor that detects the temperature of the engine will be described as an example of a sensor that detects the state of the vehicle 1.
In the in-vehicle device of the vehicle 1, first, in step 101, the warning determination means 10 configured by the CPU captures the detection value from the temperature sensor, and in step 102, the detection value captured by the warning determination means 10 is set in advance. It is determined whether an abnormal value is obtained by comparing the set value. If it is determined in step 102 that the detected value captured by the warning determination means 10 is abnormal, in step 103, an indicator lamp is turned on to indicate that the engine temperature has exceeded the normal value and is abnormally high. Is displayed to the driver. Simultaneously with the lighting of this indicator lamp, the warning judgment means 10
This abnormal value is output as a warning signal (abnormal signal) to the CPU 16 of the communication unit incorporating the GPS receiver. When a warning signal (abnormal signal) is output to the CPU 16 of the communication unit incorporating the GPS receiver, in step 104, the CPU 16 of the communication unit incorporating the GPS receiver is output.
Reference numeral 16 drives the GPS receiver 18, receives position information indicating the current position of the vehicle 1, and receives the position information data obtained from the GPS receiver 18 and a warning signal (abnormality) output from the warning determination unit 10. ) To the management station 3 using the PDC wireless module 20.

When both the position information data and the warning signal (abnormal signal) are transmitted to the management station 3 at step 104, the on-board equipment of the vehicle 1 waits for a response from the management station 3.
From the management station 3, a message for the warning signal (abnormal signal) is transmitted.
The CPU 16 of the communication unit having the built-in GPS receiver,
A message from the management station 3 is received via the PDC wireless module 20. This message says, for example, "Your car's engine is overheating. Check the safety of the following vehicle, stop on the left side of the road, and stop the engine immediately. ]. How to output this message differs depending on the road on which the vehicle 1 is traveling (general road, expressway, etc.). On the highway, for example, "Your car's engine is overheating. Watch for the following vehicle, move to the left lane, slow down, enter the service area 2 km away, stop, and immediately stop the engine. ]. At this time, "2
The "service area located a kilometer away" is a result of a search based on the positional information data transmitted from the CPU 16 of the communication unit having a built-in GPS receiver. In the case of this overheating of the engine, it is possible to return to an operable state by turning off the engine and cooling the engine. However, in some cases, so-called engine seizure may occur, and in this case, repair is required.

In the case where such repair is required, the CPU 16 of the communication unit incorporating the GPS receiver is used.
From the current location of the vehicle 1 based on the location information data transmitted from the vehicle, search for a repair shop located in a predetermined area (for example, within 3 km from the vehicle), and search for a repair shop that is optimal for repairing engine overheating; It is transmitted from the management station 3. The in-vehicle device of the vehicle 1 receives the information of the repair shop transmitted from the management station 3 in step 106. When the information on the repair shop is received in step 106, if the repair is required based on the information on the repair shop transmitted from the management station 3 in step 107, the repair shop is specified. The specific information is transmitted from the CPU 16 of the communication unit incorporating the GPS receiver to the management station 3 using the PDC wireless module 20. When the specific information of the repair shop is transmitted to the management station 3 in step 107, the management station 3 transmits a message indicating how to treat the vehicle 1 until a repair person comes from the specified repair shop. When the message transmitted from the management station 3 is received in step 108, the processing flow on the vehicle-mounted device side of the vehicle 1 ends.

On the in-vehicle equipment side of the vehicle 1, the detection value from the temperature sensor taken in by the warning determination means 10 is determined to be an abnormal value, and the C value of the communication unit incorporating the GPS receiver is determined.
A warning signal (abnormal signal) is output to the PU 16, and the CPU 16 of the communication unit incorporating the GPS receiver transmits the warning signal and the position information data obtained from the GPS receiver 18 to the management station 3 based on the transmission. In step 201, the CPU 80 of the management station 3 receives the warning signal (abnormal signal) and the position information data signal. Based on the reception of the warning signal (abnormal signal) and the position information data signal, the CPU 80 of the management station 3 transmits the warning signal (abnormal signal) and the position information data signal from the personal information database 83 to the driver's personal information ( The current address, name, age, gender, date of obtaining a driver's license, driver's license type, driver's license number, driving history, working company, contact information, telephone number, etc.) are searched to identify the individual, The vehicle is identified from the vehicle database 81 based on the data from the vehicle data of the vehicle owned by the individual (car maker, vehicle type / type, displacement, grade, body color, first year registration date, registration number, etc.).

When a warning signal (abnormal signal) and a position information data signal are received in step 201, a warning signal (abnormal signal) transmitted from the vehicle-mounted device side of the vehicle 1 indicates an emergency in step 202. The CPU 80 determines whether or not it is. If it is determined in step 202 that the warning signal (abnormal signal) transmitted from the vehicle-mounted device side of the vehicle 1 indicates an emergency, in step 203, the CPU 80 of the management station 3 side issues an emergency signal via the antenna 86. A message (character information or voice information) is transmitted to the vehicle-mounted device of the vehicle 1. Whether or not this is an emergency is determined by an abnormality (failure) occurring in the vehicle 1 and the vehicle 1 stopping if no action is taken immediately.
Unless any action is taken immediately, the failure state of the vehicle 1 becomes severe, and the vehicle cannot be repaired. The message of this emergency was "Immediately pull the car to the left and stop. ].

When the warning signal (abnormal signal) transmitted from the on-vehicle device side of the vehicle 1 indicates an emergency, the vehicle 1 is in an abnormal state (failure).
Therefore, in this step 203, the CP of the management station 3 side
When an emergency message (character information or voice information) is transmitted from U80 to the vehicle-mounted device of the vehicle 1, step 204
, The CPU 80 of the management station 3 searches for a repair shop near the vehicle 1 and transmits information on the repair shop to the on-vehicle equipment of the vehicle 1. This search for a repair shop near the vehicle 1 is based on the position information data signal transmitted from the vehicle-mounted device side of the vehicle 1, at which position on the map the vehicle 1 that has transmitted the warning signal (abnormal signal) is located. Map database 8
2, the location of the vehicle 1 on the map is specified, and a repair shop located in a predetermined area (for example, within a radius of 5 km) around the vehicle 1 is searched from the location of the vehicle 1 on the map. By doing. Further, the information on the repair shop is searched for a repair shop suitable for repairing a currently occurring failure state from among the repair shops in a predetermined area of the vehicle 1 searched in this way, and this search result is displayed. This is shown on map information. Therefore, the information on the repair shop transmitted from the CPU 80 of the management station 3 can be viewed in a state where the repair shop is displayed on a map on the display in the vehicle-mounted device of the vehicle 1.

When the information of the repair shop is transmitted in step 204, the information of the repair shop is received by the on-vehicle equipment of the vehicle 1. Vehicle 1 that received this repair shop information
On the vehicle-mounted device side, the driver specifies the repair shop based on the repair shop information transmitted from the management station 3. As this specific method, there is a method of specifying on the display of the in-vehicle device of the vehicle 1. When the driver specifies the repair shop, the specified result is transmitted from the vehicle-mounted device of the vehicle 1 to the CPU 80 of the management station 3. The transmitted specific information of the repair shop is stored in step 205.
The CPU 80 of the management station 3 receives the data. This step 20
In 5, when the specific information of the repair shop transmitted from the vehicle-mounted device of the vehicle 1 is received, in step 206, the management station 3 sends the vehicle 1 to the repair shop specified by the driver.
The position information specifying the position of the vehicle 1 on the map, vehicle data specifying the vehicle 1, and failure data indicating an abnormal state of the vehicle 1 are communicated. As a method of contacting the repair shop on the management station 3 side, there are telephone contact, FAX, mail, communication line and the like. When various data are sent to the repair shop in step 206, in step 207,
Ask the driver what to do until the garage worker arrives (for example, "Move the vehicle in the shade and stop the engine.""Stop the vehicle engine and open the hood. Wait for the workers to arrive. ").

On the other hand, if it is determined in step 202 that the warning signal (abnormal signal) transmitted from the vehicle-mounted device side of the vehicle 1 does not indicate an emergency, in step 208, the CPU 80 of the management station 3 sends the signal via the antenna 86 via the antenna 86. Then, a warning (non-emergency) message (character information or voice information) is transmitted to the vehicle-mounted device of the vehicle 1. This warning message is a message (character information or voice information) that the temperature of the engine is high. When a warning message is transmitted to the in-vehicle device of the vehicle 1 in step 208, in step 209, the CPU 80 on the management station 3 side informs the driver of a message corresponding to the driver based on the warning message (characters). Information or voice information) to the in-vehicle device of the vehicle 1. The message (character information or voice information) corresponding to this driver includes:
For example, "Your car's engine temperature is getting abnormally high. Drive at this speed, stop at the next service area, check that the radiator has enough cooling water and cool down the engine. ]. When a message corresponding to the driver is transmitted in step 209, the management station 3
The operation flow on the side is ended.
