  • Publication number: 20120290194
    Abstract: The automatic/stop restart device includes a restart control module for performing restart control for the internal combustion engine by pushing out a pinion gear (17) by a pinion-gear push-out device (18) to bring the pinion gear into meshing engagement with a ring gear (16) when the restart requirement is satisfied before the rotation of the internal combustion engine is stopped after an automatic stop requirement is satisfied. The pinion gear is pushed out when the restart requirement is satisfied when a rotation speed of the internal combustion engine is equal to or lower than a predetermined rotation speed. At the same time, a starter motor (19) is driven by a starter-motor waiting-time adjustment module for adjusting a driving waiting time for the starter motor (19) according to the rotation speed of the internal combustion engine obtained when the restart requirement is satisfied. In this manner, the restart is quickly performed.
