Abstract
A cruise control system includes a speed difference module that compares a current vehicle speed and a target cruise speed, and a brake module that selectively actuates a brake when the current vehicle speed is greater than the target cruise speed by a predetermined speed difference. A related method is also provided and includes comparing a current vehicle speed and a target cruise speed, and selectively actuating a brake when the current vehicle speed is greater than the target cruise speed by a predetermined speed difference. The method includes selectively actuating the brake based on a negative drive torque of a powerplant. The method also includes determining a desired braking force based on the current vehicle speed and the target cruise speed, and actuating the brake to generate an actual braking force less than or equal to the desired braking force.
