BODY DETECTOR FOR VEHICLE

摘要

PURPOSE:To facilitate driving operation and to improve safety by making a display device corresponding to a sensor which detects the shortest distance to a body different in display mode from others. CONSTITUTION:The output signals of ultrasonic sensors 1a-1d provided to four positions of a vehicle are inputted to a control circuit 3 through processing circuits 2a-2d. The control circuit 3 turns on display devices 7a-7d on a display board 5 through a LED driving circuit 4 to inform the approach of the body. Only a display device specified with a shortest-distance position signal among display devices 7a-7d performs an emphasized display in different mode from others by emitting, for example, high-brightness light.
