At this time, since the engine 10 has already been cranked, the engine 10 can be continuously cranked even with electric power lower than that required for starting the engine 10.
- the power control unit 602 calculates power (several seconds value) that can be output from the battery 30 in a predetermined time as described above. Therefore, although the power value (instantaneous value) that can be output instantaneously exceeds the required power, the power value (several seconds) is less than the required power, so the target motor speed is reduced more than necessary. There was a risk of being forced to do so. As the motor target rotational speed decreases, the time from cranking of the engine 10 to the complete explosion becomes longer, the reliability of the engine start is lowered, and the time until the engine start is completed is also prolonged.

If the output power (instantaneous value) of the battery 30 is greater than or equal to the required power, the process proceeds to step S43. On the other hand, when the output power (instantaneous value) of battery 30 is lower than the required power, rotation setting means 604 decreases the rotation speed of motor generator 20 for starting engine 10 in step S42. As a result, the electric power required to start the engine 10 is reduced. Note that the rotation setting unit 604 may decrease the rotation number in stages, and the rotation setting unit 604 may decrease the rotation number to a rotation number at which the necessary power becomes output power.
- step S ⁇ b> 43 voltage control unit 601 supplies electric power necessary for starting engine 10 to battery 30, and internal combustion engine starting unit 603 cranks engine 10.
