Abstract
An ECU is mounted on a vehicle including an engine and a motor that can generate cranking torque applied to a rotation shaft of the engine. Where a request for starting the engine is not issued, the ECU determines whether the engine is during coasting or not. The ECU changes cranking target torque in accordance with engine rotation speed. In this way, engine rotation speed during cranking can be reduced to and remain in the optimum region where misfire and resonance can be avoided.
