Abstract:
In a vehicle including an engine and a motor generator that are connected to a drive wheel, when a predetermined condition is satisfied during a motor creep mode in which creep torque is generated by the motor generator, an ECU performs motor creep cutoff for decreasing torque of the motor generator. When an engine start request has been issued during the motor creep cutoff, the ECU increases the torque of the motor generator to a target creep torque at a predetermined rate of increase. After the MG torque has reached the target creep torque, the ECU starts the engine. The predetermined rate of increase is set to a rate lower than a rate of increase in engine torque at the start of the engine.
