Abstract
A system and method for controlling speed of a vehicle include determining whether or not a stand-by braking torque is applied, determining an actual distance from a preceding vehicle in front of a vehicle, comparing the actual distance to a desired distance to determine whether the actual distance is greater than the desired distance, determining motor/engine torque to increase vehicle speed, and applying the motor/engine torque when the actual distance is greater than the desired distance. The system and method terminates application of stand-by braking torque upon receiving operator torque request.
