Abstract

In order to improve the reliability of engine starting by using a motor, the engine cranking using the motor is started according to a request for starting the engine, and when the elapsed time from the starting time of the engine operation reaches a first predetermined time and it is detected that the transmission is in the in-gear state, the engine cranking is continued if the engine speed is equal to or less than a predetermined engine speed defined for determining whether the engine reaches a predetermined starting phase. The engine cranking may be continued for a second predetermined time which is longer than the first predetermined time.
