    摘要: A fault clearing system and method for an engine control system includes a plurality of processor modules to control and monitor the engine and set a plurality of faults. The plurality of processor modules includes an electronic throttle control (ETC) module to control and monitor a throttle of the engine, and a plurality of engine sensors and ETC sensors. An ETC diagnostic module monitors the ETC sensors and engine sensors, with the ETC diagnostic module setting a low voltage induced fault. The ETC diagnostic module will also enter one of a plurality of low voltage states in response to the low voltage induced fault. The ETC diagnostic module selectively controls the ETC module and selectively clears the faults in the ETC module and plurality of processor modules upon entry into one of the low voltage states.

    摘要: A system for a vehicle includes a desired mass air flowrate (MAF) module and a desired effective area module. The desired MAF module generates a desired MAF through a throttle valve of an engine based on an engine torque request. The desired effective area module generates a desired effective area of the throttle valve based on a throttle inlet air pressure (TIAP) and the desired MAF. A throttle actuator module adjusts opening of the throttle valve based on the desired effective area.

    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.
