IMPACT ENERGY REDUCING DEVICE IN REAR-END COLLISION OF VEHICLE

摘要

PPROBLEM TO BE SOLVED: To provide an impact energy reducing device at the time of rear-end collision of a vehicle capable of precluding a contacting interference with any obstacle lying ahead at the time of rear-end collision and also reducing the impact energy due to rear-end collision while the risk of making rear-end collision in the brake stopped condition is avoided. PSOLUTION: The impact energy reducing device is equipped with a backward inter-vehicle distance sensor to sense the condition of the following vehicle and an associated collision sensor, a forward inter-vehicle sensor to sense the inter-vehicle distance between any obstacle lying ahead and the vehicle concerned, and a forward movable distance setting means to set the forward movable distance from the stop position of the vehicle to the position not attaining the obstacle on the basis of the sensed value of the inter-vehicle distance given by an inter-vehicle distance sensing means, and a vehicle movement controlling means to weaken the braking force when judgement is such that at least a rear-end collision is possible on the basis of the backward vehicle condition given by a backward vehicle condition sensing means while it is the brake stopped situation, and to admit movement of the vehicle concerned for the forward movable distance set by the forward movable distance setting means.
