Estimating the term…
A hybrid vehicle of the disclosure includes an engine, a motor that outputs a torque to a driving system, a hydraulic clutch that connects the engine with the motor and disconnects the engine from the motor, and a control device that performs slip control of the hydraulic clutch in response to satisfaction of a start condition of the engine and controls the motor to output at least a cranking torque to the engine. The control device sets a target value of a rotation speed difference between the engine and the motor during execution of the slip control, and increases at least one of a hydraulic pressure to the hydraulic clutch, an output torque of the motor and an output torque of the engine when a difference between the rotation speed difference and the target value is out of an allowable range. This configuration ensures good startability of the engine.
A hybrid vehicle comprising:
A control method of a hybrid vehicle that includes an engine, a motor configured to output a torque to a driving system, and a hydraulic clutch configured to connect the engine with the motor and to disconnect the engine from the motor, the control method of the hybrid vehicle comprising:
