Abstract

See full text

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.
