Abstract

A controller is provided for a parallel hybrid electric vehicle. The vehicle powertrain includes an engine, an electric propulsion motor powered by an energy storage device, and an electric generator driven by the engine to recharge the energy storage device. The controller receives one or more signals indicative of one or more operating modes in which the vehicle is to be operated; receives a signal indicative of demanded powertrain drive torque; and causes the engine and electric propulsion motor to deliver drive torque to one or more wheels to drive the vehicle. The controller causes the powertrain to operate in a parallel powertrain mode, where the amount of torque delivered by the electric propulsion motor is determined by the controller in dependence on the signal indicative of demanded powertrain drive torque and the one or more signals indicative of the one or more operating modes.
