Provided is a valve open/close timing control system where a valve open/close timing control device includes a drive-side rotating member, a driven-side rotating member, a relative rotational phase control mechanism, and a first locking member, in which the internal combustion engine is configured to be started by a drive force generated by a traveling motor or by a drive force generated by a starter motor, and the valve open/close timing control system also includes a control unit which is configured, for starting the internal combustion engine while changing the relative rotational phase at the time of starting the internal combustion engine, to drive the starter motor or the traveling motor at the time of starting the internal combustion engine at the first locking phase, and to drive the traveling motor at the time of starting the internal combustion engine at the second locking phase. |
