Abstract:
An engine clutch control device of a hybrid vehicle and a temperature control method of an engine clutch using the same are provided to secure the stable traveling of the vehicle under various traveling conditions by preventing a burn and malfunction of the clutch caused by high heat. In an engine clutch control device of a hybrid vehicle for preventing power from being cut off by the increase of temperature on the surface of a clutch(10) if the hybrid vehicle goes slowly in a standby state or on the slope, a calculation unit(100) receives variable values for initial temperature information of oil of a transmission for the hybrid vehicle, RPM(Revolution Per Minute) information about relative RPM of a driving shaft and an output shaft outputting power generated from an engine, information about pressure applied to the clutch, and time information. And, the calculation unit computes temperature of a clutch plate(2) to protect the clutch. A control unit(200) controls the clutch through multiple stages according to the temperature generated from the clutch plate, by receiving a result value output from the calculation unit and prevents a burn of the clutch by controlling hydraulic pressure supplied to the clutch.
