Abstract
The aging society comes, and the accident because of the physical condition sudden change while driving will have the fear of an increase in the future.The vital information of the driver under driving is continuously recorded by using the ECG sensor installed in the steering wheel, the heart beat variety analysis is done, and the system that catches the modulation of the autonomic nervous system thought to be a sign of the cardiac event at the early stage is researched. It will leads to the prevention of a serious accident by the cardiac event while driving before it that it can be cautioned to the driver at the stage before the control of the car becomes difficult by the cardiac event, and the control of the safe stop of the car becomes possible if this system will be realized. In the achievement of the system, the Noise-proof and the individual variation will become problems. In addition, it is thought to be necessary here that not only the sensor and the logic technology but also social consensus to accept it to be cooperation with the medical treatment system and vehicle communication system will be necessary.
