ABSTRACT:
A system and method for reducing speed of a vehicle to maintain a target vehicle speed include determining an actual vehicle speed, comparing the target vehicle speed to the actual vehicle speed to generate a speed error, determining a continuously variable braking torque as a function of the speed error when the actual vehicle speed exceeds the target vehicle speed, and applying the continuously variable braking torque to at least one wheel of the vehicle to reduce the speed error toward zero and control the speed of the vehicle. The present invention is applicable to vehicles powered by an internal combustion engine, electric vehicles, fuel cell vehicles, and hybrid vehicles. The continuously variable braking torque may be applied using regenerative braking to improve fuel efficiency. Friction brakes may also be utilized either alone, or in combination with regenerative braking, for vehicles capable of brake-by-wire control strategies.
