摘要:
An engine is coupled to an input member of a hybrid transmission and the hybrid transmission is operative to transfer torque between the input member and a torque machine and an output member to generate an output torque in response to an operator torque request. The torque machine is connected to an energy storage device. A method for controlling the engine includes determining a preferred input torque from the engine to the hybrid transmission based upon operator inputs to an accelerator pedal and a brake pedal, determining maximum and minimum allowable input torques from the engine to the hybrid transmission, controlling the engine at the preferred input torque when the preferred input torque is within the maximum and minimum allowable input torques, and controlling the engine based upon the maximum and minimum allowable input torques when the preferred input torque is outside one of the maximum and minimum allowable input torques.
