    摘要： A method of controlling engine crankshaft motion in a hybrid electric drive system having an internal combustion engine and a motor-generator operatively connected to a crankshaft of the engine is disclosed. The steps include monitoring the crankshaft position, forecasting a crankshaft stall position; comparing the forecast stall position with a target range; and if the forecast crankshaft stall position is outside the target range, operating the motor-generator to modify the forecast stall position to be within the target range. These steps properly position the crankshaft for re-initiating engine start-up. The method further includes the steps of calculating an effective lube interval time once the crankshaft speed is zero; comparing the effective lube interval time to a critical time; and if the effective lube interval time is greater than the critical time, pulsing the motor-generator to rock the crankshaft for a pulse time to redistribute a lubricant film.

    摘要： A fuel delivery control system includes a vehicle speed sensor that generates a vehicle speed signal and an engine rotational speed sensor that generates an engine rotational speed signal. A control module calculates at least one of an accelerator release delay period and a brake depression delay period based on the vehicle speed signal and the engine rotational speed signal and deactivates fuel delivery to said engine after waiting at least one of the accelerator release delay period after the accelerator pedal is released and the brake depression delay period after the brake pedal is depressed.

    摘要： The method of the present invention provides a variety of vehicle performance characteristics depending on the mode of operation. A first routine is initiated to provide an optimal balance of powertrain responsiveness and fuel economy for any given combination of vehicle speed and deceleration rate. The first routine may, according to a preferred embodiment, include a plurality of routines that are each configured to provide an optimal balance of powertrain responsiveness and fuel economy within a predefined range of vehicle speeds and deceleration rates. A second routine is initiated if said deceleration rate is within a predefined range. The second routine includes running the electric motor/generator while the hybrid vehicle is being stopped in order to control the driveline lash and thereby minimize disturbances during a subsequent engine re-start.
