METHOD OF CONTROLLING THE STOPPING AND STARTING OF AN ENGINE

摘要

A method of stopping and starting an engine of a vehicle having a manually operated clutch system including a clutch for driveably connecting the engine to a transmission includes controlling stopping and starting of the engine based on first and second clutch engagement thresholds selected based on whether the clutch is being engaged or disengaged. The first threshold corresponds to a more disengaged state of the clutch than the second threshold. The first threshold is used when the clutch is being disengaged to decide whether the engine can be shut down while the transmission remains in-gear. The second threshold is used when the clutch is being engaged to decide whether the engine can be started while the transmission remains in-gear. By using a less conservative threshold for starting the engine than stopping the engine, the number of inhibited restarts is reduced.

主权项

1. An engine control method for a vehicle, comprising:
stopping the engine, by a controller, in response to disengaging a manual transmission clutch and the clutch being more disengaged than a first clutch disengagement threshold; and restarting the engine, by the controller, in response to engaging the clutch and the clutch being more disengaged than a second clutch disengagement threshold corresponding to a less disengaged clutch state than the first clutch disengagement threshold.
