Abstract

It is reported that more than half a million souls are lost per year due to traffic accidents throughout the world. These losses have been a very serious topic. Until now, no one could understand or supervise a driver'"'"'s driving behavior, unless a supervisor was with him in the same vehicle. By the use of recent computer and communication technologies, we invented a system based on our safe driving theory, for a supervisor from a remote place to supervise and train drivers to drive safely. A computer in a vehicle obtains information concerning the driver'"'"'s driving behavior by sensors in the vehicle and sends it to a supervisor outside of the vehicle. The supervisor can recognize unsafe behavior and train the driver in safe driving.

Claims

1. In order to maintain safe driving, a system that measures and records the position and speed of a vehicle and sends data about driving behavior to a supervisor at a remote place automatically if a driver does not stop at a crossroad where he/she should stop.

3. A system claimed in claim 1 that sends a front view image from a camera in the vehicle to a remote place, if the driver does not stop at a crossroad where a driver should stop.

2. In order to maintain safe driving, A system that measures following distance and position of a vehicle and sends the driving behavior to a supervisor at a remote place automatically if the following distance is less than a criterion.

4. A system claimed in claim 2 that sends a front view image from a camera in the vehicle to a remote place, if the following distance is less than a criterion.

5. A system claimed in claim 2 that estimates a stopping distance of the vehicle and if the following distance is less than the stopping distance, it notifies the driver or the supervisor.
