Collision prediction device

A collision prediction apparatus comprising:

• a running track prediction means for predicting a running track of an own vehicle;
• an estimated curve radius means for estimating a curve radius of the own vehicle based on a real-time parameter of the own vehicle;
• a positional relationship detection means for detecting a relative positional relationship between a collision candidate moving body and the own vehicle;
• a collision direction prediction means for predicting a collision direction of the collision candidate moving body with respect to the own vehicle based on the estimated curve radius calculated by the estimated curve radius computing unit;
• a collision surface selection means for selection a collision surface from a plurality of collision surfaces of the own vehicle with the collision candidate moving body according to the predicted collision direction of the collision candidate moving body with respect to the own vehicle predicted by the collision direction prediction means;
• a collision position calculation means for calculating, after the collision surface selection means selects the collision surface, a collision position of the own vehicle with the collision candidate moving body according to the selected collision surface, the predicted running track, and the relative positional relationship,
• wherein only the collision position corresponding to the selected collision surface is calculated in order to reduce a computational load on the collision position calculation means;
• the collision position calculation means for generating and outputting a deceleration signal to a breaking means according to the calculated collision position;
• and
• the breaking means for actuating a break actuator according to the deceleration signal thereby controlling the deceleration of the own vehicle.
