Abstract:
1. A control device of a hybrid vehicle, the hybrid vehicle having 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 having 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 performing the ignition start of the direct injection engine during the MG creep mode and providing 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.
