However, in the above-mentioned conventional apparatus, since it is not possible to obtain comprehensive information on the state of the vehicle, there has been a problem that the driver cannot be properly advised. In addition, the vehicle operation control center and the emergency rescue center do not have a detailed understanding of the situation of the vehicle, so it is necessary to collect more information in order to take appropriate measures, There was a problem that it took time to take measures. For example, when the operation control center detects that the vehicle has been stopped for a certain period of time, it is not known whether the vehicle has run out of fuel on a mountain road or has fallen into a river because the altitude of the vehicle and the reason for the stop are unknown. Therefore, it took time to collect accident information to determine whether to dispatch a helicopter or an ambulance.

[0005] The present invention solves the above-mentioned problems, notifies the driver of detailed information of the vehicle to prevent an accident or the like, and transmits the detailed information of the vehicle to the center to efficiently drive the vehicle. The purpose is to perform management and rescue operations.

[0006]

According to the present invention, there is provided an in-vehicle detailed information acquiring apparatus for acquiring, storing, and wirelessly transmitting vehicle information to a center by using a GPS. A device for measuring position, a gyro device,
The navigation system, the information terminal device, the mobile phone, the audio device, the fuel gauge, the speedometer, the transmission, and the engine control device are connected to at least one of them. With this configuration, it is possible to transmit data to the database management system of the center and acquire vehicle detailed information from the vehicle number and the like.

[0007] Further, the display is connected to means for recognizing the travel regulation speed by photographing the display of the travel regulation speed on the road surface with a CCD camera. With this configuration, when the speed exceeds the driving regulation speed, the driver can be alerted by voice and the number of traffic accidents can be reduced.

Further, a means is provided for notifying the center of the acquired in-vehicle detailed information at predetermined times. With this configuration, on a regular basis or when an accident occurs,
The detailed situation of the vehicle can be grasped at the center.

Further, a means for warning the driver based on the acquired in-vehicle detailed information is provided. With such a configuration, the driver can be alerted by voice and a traffic accident can be reduced.

Further, the in-vehicle detailed information includes at least one of a vehicle position, a traveling direction, an hourly speed, an average speed, an altitude, a remaining fuel amount, a gear position, and a brake state. With this configuration, it is possible to grasp a detailed situation of the vehicle and perform warning and state management.

Further, there is provided means for transmitting the accumulated in-vehicle detailed information to the portable information terminal via infrared communication means.
With this configuration, a patrol officer, a police officer, or the like captures the state of the vehicle on a personal digital assistant (PDA) and transmits it to the center via a modem, so that the status of the vehicle can be grasped.
