ABSTRACT:
A plurality of ultrasonic sensors are installed at predetermined positions of an automotive vehicle. Each sensor has the capability of performing calculation for measuring a distance between an obstacle and the automotive vehicle and transmitting distance information representing a measured distance of the obstacle. A control unit receives the distance information and generates an alarm signal based on the distance information.
