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： An internal-combustion-engine automatic stop and restart system performs restarting control by making the pinion pushing unit push out the pinion gear so as to engage with the ring gear, when the restarting condition is satisfied in a time period from a time when the automatic stopping condition is satisfied to a time when the rotation of the internal combustion engine stops. A throttle valve control unit opens the throttle valve even when the restarting condition has not been satisfied and stops control of the throttle valve in a time period from when the rotation of the internal combustion engine stops to when the restarting condition is satisfied, when the rotation speed of the internal combustion engine becomes lower than a predetermined value in a time period from when the automatic stopping condition is satisfied to when the rotation of the internal combustion engine stops.

摘要： In a case where the end of a gear change has been decided by gear change end decision means for deciding if a transmission has undergone the gear change, the coil resistance value of a motor which manipulates the transmission is measured by coil resistance measurement means. The coil temperature of the motor is estimated from the measured coil resistance value of the motor by coil temperature estimation means. In a case where the estimated coil temperature of the motor has been decided to be predetermined temperature or above by high-temperature decision means, the speed change inhibition time period of the transmission is calculated by speed change inhibition time calculation means, and the speed change of the transmission is inhibited during the calculated speed change inhibition time period.
