Patent ID: 8000885

Claim:
An engine stop control device that performs engine stop control for controlling an engine rotation behavior with torque of an alternator such that an engine rotation stop position is controlled to a target stop position when the control device stops engine rotation in response to an engine stop request, the control device comprising: a reference point target rotation speed setting means for setting target rotation speed at a reference point, which is set at a point preceding the target stop position by a predetermined crank angle, the target rotation speed at the reference point being unchanged during the engine stop control; a target trajectory calculating means for calculating a target trajectory of the engine rotation behavior extending since the engine stop control is started until the target rotation speed at the reference point is reached based on the target rotation speed at the reference point and an engine friction; and a stop controlling means for controlling the torque of the alternator to conform the engine rotation behavior to the target trajectory during execution of the engine stop control.
