Abstract
A system and method for controlling vehicle speed include mutually exclusive closed loop controllers for vehicle speed and acceleration which control vehicle speed by requesting an appropriate wheel torque. The system and method compute, in real time, the wheel torque required to maintain steady vehicle speed or steady acceleration depending on the particular mode of operation. The active closed loop controller acts upon vehicle speed or acceleration errors to output a desired torque request.
