ABSTRACT:
A collision-prediction unit for a vehicle including a road condition detector, a maximum deceleration estimator, a forward vehicle detector, a forward vehicle deceleration calculator, and a collision examiner is provided. The road surface detector detects a condition of a road surface on which the vehicle travels. The maximum deceleration estimator calculates a maximum vehicle deceleration for the vehicle on the road surface having the detected condition. The forward vehicle detector detects a moving condition of a forward vehicle located ahead of the vehicle. The forward vehicle deceleration calculator calculates a forward vehicle deceleration based on the moving condition of the forward vehicle. The collision examiner determines whether a collision between the vehicle and the forward vehicle is imminent by comparing the forward vehicle deceleration to the maximum vehicle deceleration of the vehicle.
