Collision mitigation device for vehicles

Collision mitigation means to mitigate the damage to a vehicle at the time of a collision on the collision mitigation device is mounted, comprising: an operation control unit which detects an existing in the surroundings of the vehicle collision object that performs a comparison between a time of collision, which is indicative of the time remaining with the collision object in front of the collision of the vehicle, and an operating reference time period, thus the timing for the start of the control is set for collision avoidance, and which causes a vehicle-mounted collision attenuation device to go depending on a result of the comparison in operation; a calculation unit for the collision probability, which calculates the probability of collision between the vehicle and the collision object; and a unit for setting the reference time period, which adjusts the operating reference time period depends on the collision probability. wherein the collision mitigation device further comprises a unit which estimates a collision position in the transverse direction of the vehicle between the collision object and the vehicle, the unit being designed for setting the reference time period in such a way that it adjusts the operating reference time period depends on the collision probability and further from the collision position. wherein the unit for estimating the position in the transverse direction estimates a collision depth than the collision position, which is indicative of a distance which exists between a nearer the collision object corner of the vehicle and the collision position, the unit being designed for setting the reference time period so as to increase the operating reference time period with increase in the collision depth, wherein the collision mitigation device further comprises a unit for detecting a hidden state, which determines whether the collision object is in a hidden state or not, in which ...
