摘要:
The hybrid vehicle has a motor generator disposed in a power transmission path and performing as an electric motor and an electric generator, a direct injection engine configured to execute an ignition start in which fuel is injected into any cylinder with a piston stopped in an expansion stroke and ignited for the start, and an engine connecting/disconnecting clutch of friction engagement type directly connecting and interrupting the direct injection engine to/from the motor generator. The control device of the hybrid vehicle has an MG creep mode in which the motor generator is used as an electric motor and rotationally driven at a predetermined first rotation speed to generate a creep torque while the engine connecting/disconnecting clutch is interrupted and the direct injection engine is stopped, and a charging creep mode in which the direct injection engine is operated at a predetermined second rotation speed higher than the first rotation speed to generate the creep torque with the motor generator used as an electric generator to charge a battery while the engine connecting/disconnecting clutch is connected, the control device performs the ignition start of the direct injection engine during the MG creep mode and provides connection control of the engine connecting/disconnecting clutch after a rotation speed of the direct injection engine exceeds a rotation speed of the motor generator to raise the rotation speed of the motor generator and directly connect the direct injection engine to the motor generator when a transition is made from the MG creep mode to the charging creep mode.
