    • Target rotation speed at a reference point set at TDC slightly preceding a target stop position of engine rotation is set. A target trajectory of an engine rotation behavior extending since an engine rotation stop behavior starts until the target rotation speed at the reference point is reached is calculated based on the target rotation speed at the reference point and an engine friction. Torque of an alternator is controlled to conform the engine rotation behavior to the target trajectory during the engine rotation stop behavior. Generation of the torque of the alternator stops at a position preceding the reference point by a predetermined crank angle. Therefore, the torque of the alternator is controlled such that an energy deviation between the target trajectory and the engine rotation behavior becomes zero at the position preceding the reference point by the predetermined crank angle.
    • 设定在稍稍在发动机旋转的目标停止位置之前的TDC处的基准点处的目标转速。 根据基准点的目标转速和发动机摩擦来计算从发动机转速停止行为开始直到目标参考点的转速达到的发动机旋转行为的目标轨迹。 在发动机旋转停止行为期间,控制交流发电机的扭矩以使发动机旋转特性符合目标轨迹。 交流发电机的转矩的产生在参考点之前的位置停止预定的曲柄角。 因此,控制交流发电机的扭矩,使得目标轨迹和发动机旋转行为之间的能量偏差在参考点之前的位置处为预定的曲柄角度为零。
