Collision damage reduction system

A computer-readable program product used for a collision damage reduction system, in which said collision reduction system is installed on an vehicle and has 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, a first detecting unit configured to regularly detect relative position data corresponding to a relative position between the vehicle and the object and a second detecting unit configured to regularly detect a speed of the vehicle, said program product comprising:

• means for causing a computer to determine 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 causing a computer to obtain 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 causing a computer to calculate 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 causing a computer to instruct the operation unit to operate at least one of the first operation and the second operation according to the total collision probability.
