Abstract
Disclosed is a method and power delivery system for controlling creep torque in a hybrid or electric vehicle. More specifically, a brake signal is detected and a creep torque output is controlled based on the brake signal. The creep torque is outputted for a predetermined time from a point when a brake on signal is first generated. Accordingly, a creep torque is generated for a predetermined time when a brake is being operated and backlash is eliminated between gears so as to prevent a backlash shock from the gears when the brake is released. Additionally, the vehicle may be propelled forward or backward by the creep torque in the creep torque control method of a vehicle according to an exemplary embodiment of the present invention.
