Abstract

PURPOSE:To know the distance between vehicles and prevent accidents of dashing from behind by combining the three: a microcomputer, a radar mounted to a vehicle and a speed detector of the vehicle. CONSTITUTION:The electric signal (a) from a radar 1 mounted to the front of a vehicle and an electric signal (b) derived from a vehicle speed detector 2 in a speed meter are inputted to a microcomputer 3, which performs subtracter calculation (a-b) and divisor calculation (a/b). This is so formed that when the value of (a-b) assumes a negative figure, a lamp 4 begins to turn on/off and when (a/b) assumes a figure below a certain value, a buzzer 5 sounds. Thereby, the distance between vehicles is known and the accidents of dashing from behind are prevented.
