Between-car distance controller

Abstract

Abstract PURPOSE:To certainly maintain the safe between-car distance by controlling the acceleration and deceleration of a car on the basis of the car speed and the variation rate of the difference between the actual between-car distance and the safe between-car distance with time. CONSTITUTION:The car-speed information detected by a car-speed sensor 55 is supplied into a control unit 49. A rader sensor 61 transmits electromagnetic waves in front of a car and receives the reflected waves and supplied them into the control unit 49, and the between-car distance to a car ahead is calculated. The safe between-car distance corresponding to car speed is compared with the actual between-car distance, and the traveling speed is controlled according to the variation of the distance difference with time.
