  • Publication number: 20240270233
    Abstract: A driving system for a vehicle includes an engine including a fuel injection valve, an electric motor, a hydraulic clutch which connects/disconnects the engine to/from the motor, a hydraulic pressure sensor which detects hydraulic pressure of the clutch, and a controller which selectively executes one of a motor travel mode where the motor is activated and the engine is stopped, and an engine travel mode where at least the engine is activated. In a startup of the engine accompanying a change from the motor travel mode to the engine travel mode, the controller causes the clutch to transition from a disconnected state to a connected state, determines the connected state of the clutch based on hydraulic pressure detected by the hydraulic pressure sensor, and when the clutch is confirmed to be in a predetermined connection initial state, the controller causes the fuel injection valve to inject fuel.
