Abstract
A distance and a relative velocity between a vehicle and a vehicle in front are detected, and the minimum braking force required to avert a collision is calculated. A vehicle braking force based on the depression angle of the brake pedal and the minimum vehicle braking force are compared, and the larger of these two forces is applied for braking. Collision of the vehicles is thereby prevented. Preferably, the braking force is distributed to each of wheel brakes according to the dynamic loads acting on each wheel so that braking force is optimized and the wheels do not easily lock. More preferably, an alarm is issued when the vehicle braking force based on the brake pedal depression angle is less than the minimum vehicle braking force so that the driver is alerted to this fact.
