  • Patent number: 11959449
    Abstract: A control device for a hybrid electric vehicle includes an electronic control unit. The electronic control unit is configured to perform a start-up control of shifting the connection and disconnection clutch to a coupled state at the time of starting the internal combustion engine to rotate the internal combustion engine by the driving torque of the electric motor, and starting the first fuel injection mode using the direct injection injector. The electronic control unit is configured to switch from the first fuel injection mode to a second fuel injection mode for using the port injector prior to an end of the start-up control when the number of times of combustion cycles of the internal combustion engine with the first fuel injection mode reaches a predetermined first target number of times.
