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.

10. A vehicle comprising:
-
an engine; a motor that can generate cranking torque applied to a rotation shaft of said engine; and a control device that controls said motor so that said cranking torque becomes a target torque when a starting request of said engine is issued; when said starting request is issued during coasting of said engine, said control device setting said target torque when a rotation speed of said engine is higher than a threshold speed to be a value lower than said target torque when said rotation speed is lower than said threshold speed, and said threshold speed being a value corresponding to a lower limit value of a rotation region where misfire of said engine occurs in a state where an amount of intake air to said engine is smaller than a predetermined amount. - View Dependent Claims (11, 12, 13, 14, 15, 16)
