摘要：
When an engine automatic stop judgment unit (101) judges that an engine automatic stop condition is satisfied so that a fuel injection control unit (105) stops fuel supply to an engine and an ignition control unit (106) stops ignition of the engine, and when an engine restart judgment unit (102) judges that an engine restart condition is satisfied before the engine stops, the pinion gear is driven to rotate. Then, engagement between the ring gear and the pinion gear is started when a deviation between an rpm of the engine detected by an engine rpm calculation unit (104) and an rpm of the pinion gear becomes smaller than a predetermined threshold value. Ignition by an ignition control unit (106) is inhibited during a period from start of the engagement until an engagement completion judgment unit (103) judges that the engagement is completed.
摘要（中）：
当发动机自动停止判断单元（101）判断为满足发动机自动停止条件使得燃料喷射控制单元（105）停止对发动机的燃料供给并且点火控制单元（106）停止发动机点火时，以及 当发动机重起判断单元（102）在发动机停止之前判定发动机重起状态满足时，小齿轮被驱动旋转。 然后，当由发动机转速计算单元（104）检测到的发动机的转速和小齿轮的转速之间的偏差变得小于预定阈值时，开始齿圈与小齿轮之间的接合。 在接合开始期间，接合完成判断单元103判定接合完成之后，点火控制单元（106）的点火被禁止。
