摘要 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.

主权项 1. A vehicle comprising: an engine; 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 in which combustion does not occur, said control device changing said target torque such that a corresponding value of a rotation speed of the engine is changed from being higher than a predetermined threshold speed to being lower than said predetermined threshold speed and such that misfire of said engine is avoided, said predetermined 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 wherein said predetermined threshold speed is a value corresponding to the lower limit value of the rotation region where misfire of said engine occurs in a state where an amount of intake air to said engine is a minimal amount.
