Abstract

PURPOSE:To afford convenience to vehicle drivers by making generation of signal of the distance between vehicles unable when a large vehicle is going to break-into by means of sending alarm prohibition signals for prefixed time period after any breaking-in is detected. CONSTITUTION:This alarm consists of a detector 1 for the distance between vehicles and relative speeds, an information treatment unit 2 and an alarm device 3 outputting signals when the distance between vehicles become less than the safety distance, a detector circuit 4 for detecting the breaking-in based upon the signal of distance between vehicles, and a timer circuit 6 for supplying signals for prohibitting alarm generation for the predetermined time period when a breaking-into detector signal is outputted. The time period set in the timer is devised to be longer than the period in which the distance from the breaking-in vehicle becomes equal to the safety distance.
