Abstract
An engine is cranked by a motor generator at a start time of the engine. An engine ECU opens an intake valve or an exhaust valve during a compression stroke using a valve control mechanism during a period from when cranking is started until when a predetermined crank angle position (detected by a crank angle sensor) is reached, thereby reducing a compression workload.
