摘要:
A hybrid powertrain and a method of controlling a throttle in an engine of the hybrid powertrain are provided. A throttle system has a throttle at an optimal position for the engine to power a first motor/generator when an electric throttle motor is de-energized to minimize current consumption by the throttle motor. The electric throttle motor is energizable to adjust the position of the throttle. A biasing member biases the throttle to a default position when the electric throttle motor is not energized. The hybrid powertrain has a first motor/generator operatively connected to the engine, and a second motor/generator operatively connected to the generator and operable for providing output power. The engine is operable in a predetermined optimal state to provide power to the generator for powering the first motor/generator. The throttle is at a predetermined position when the engine is in the predetermined optimal state.
