Control system and control method

A control method for a vehicle, the vehicle including an engine, a clutch and an electronic control unit, the engine being configured to start up by cranking, the clutch being configured to transmit cranking torque to the engine when engaged, the clutch being configured so as to continuously change its transmitted torque capacity, the control method comprising:

• cranking, by the electronic control unit, the engine by setting the clutch in a half engaged state in a state where operation of the engine is stopped during traveling, the half engaged state being a state where the clutch is engaged with a slip;
• and
• after a rotation speed of the engine has reached an ignition permission rotation speed or higher, increasing, by the electronic control unit, the transmitted torque capacity of the clutch to a transmitted torque capacity that satisfies the following conditions i) and ii):
• i) the transmitted torque capacity increases immediately when the rotation speed of the engine has reached the ignition permission rotation speed;
• and
• ii) the transmitted torque capacity allows the clutch to be kept in the half engaged state.
