Abstract:
A hybrid vehicle includes an engine and an electric machine, both capable of propelling the vehicle. The electric machine provides creep torque to propel the vehicle at a slow speed or hold the vehicle when on an incline. At least one controller is programmed to cancel or otherwise inhibit the electric machine from generating the creep torque in response to a brake torque or brake torque request exceeding a calibratible threshold. The calibratible threshold varies based upon vehicle incline, vehicle mass, and/or vehicle speed.
