Abstract
A method and system for braking a hybrid electric vehicle having an internal combustion engine and a traction motor coupled to a common output shaft, with the vehicle also having an energy storage battery. The method includes monitoring of the vehicle to determine if the vehicle's driver is operating the vehicle in a braking mode and if so, controlling the engine and traction motor so as to provide dynamic braking such that when the traction motor is operated regeneratively, the brake torque produce by the engine is reduced from a maximum contemporaneous brake torque value.
