Collision damage reduction system
First Claim
1. A collision damage reduction system installed on a vehicle and having an operation unit capable of performing at least one of a first operation of avoiding a collision of the vehicle with an object and a second operation of reducing damage in the collision, said system comprising:
- a first detecting unit configured to regularly detect a relative position data corresponding to a relative position between the vehicle and the object;
a second detecting unit configured to regularly detect a speed of the vehicle;
means for determining a probability of operation that a driver of the vehicle will carry out an operation for avoiding the collision of the vehicle with the object;
means for obtaining a first performance limit data of the vehicle according to the detected speed thereof and the determined operation probability, and a second performance limit data of the object according to the relative position data and the detected speed of the vehicle;
means for calculating a total collision probability representing a probability that the vehicle and the object will collide with each other on a runnable space according to the first performance limit data, the second performance limit data, the detected speed of the vehicle and the relative position data, said vehicle and object being runnable on the runnable space; and
means for instructing the operation unit to operate at least one of the first operation and the second operation according to the total collision probability.

Abstract
In a collision damage reduction system, a microcomputer obtains relative position data corresponding to a relative between a vehicle and an object from a first detecting unit, the detected speed of the vehicle as detected by a second detecting unit, the detected turning angle of the vehicle as detected by a third detecting unit. The microcomputer calculates a total collision probability representing a probability that the vehicle and the object will collide on a runnable space according to the relative position data, the detected speed of the own vehicle and the detected turning angle. In addition, the microcomputer instructs the operation unit to operate at least one of a first collision avoidance operation and a second collision avoidance operation according to the total collision probability.
