Abstract:
1. A clutch control device of a hybrid vehicle, the clutch control device comprising: a clutch which engages a motor shaft driven by a motor and connected with a drive shaft and an engine shaft driven by an engine with each other, the clutch which releases the motor shaft and the engine shaft from each other; a hydraulic unit which controls the clutch by an oil pressure of an oil; an oil temperature detecting unit which detects an oil temperature of the oil; a vehicle velocity detecting unit which detects a vehicle velocity of the hybrid vehicle; and a control unit which switches a driving mode between an engine driving mode in which the motor shaft and the engine shaft are engaged with each other and the hybrid vehicle is driven by the engine and a motor driving mode in which the motor shaft and the engine shaft are released from each other and the hybrid vehicle is driven by the motor, by controlling the clutch through the hydraulic unit, the control unit which, when the driving mode is switched from the engine driving mode to the motor driving mode, acquires a response time in which a state of the clutch is changed from an engaged state to a released state based on the oil temperature and the vehicle velocity, determines that the clutch is released, after the response time elapses after starting to control the clutch to release the motor shaft and engine shaft from each other, and permits control in the motor driving mode.
