Abstract
An apparatus for preventing collision of a vehicle comprises PA1 A device for measuring a distance R from a driving vehicle to an obstacle and a relative velocity V of the driving vehicle to said obstacle; PA1 A circuit for generating a damping signal when the relation of the distance R, the relative velocity V and a preset deceleration .alpha. becomes the relation of R < V.sup.2 /2.alpha.; PA1 a deceleration detector for detecting the actual deceleration .alpha.' of the driving vehicle; PA1 A correction circuit which compares the actual deceleration .alpha.' detected by the deceleration detector with the preset deceleration .alpha. and the damping signal is corrected depending upon the comparative data.
