A clutch control device for a hybrid vehicle comprising: an automated manual transmission which transmits a rotation of an input shaft adapted to be rotated by an engine torque outputted from an engine mounted on the hybrid vehicle to a drive wheel (16a, 16b) of the vehicle by changing a rotation speed of the input shaft to a plurality of speed stages with a plurality of speed change ratios; a motor connected to the drive wheel (16a, 16b) of the vehicle; a clutch device for engaging the output shaft of the engine with the input shaft of the automated manual transmission or disengaging the output shaft of the engine from the input shaft of the automated manual transmission and controlling a clutch torque transmitted to the input shaft of the automated manual transmission from the output shaft of the engine to be a target clutch torque; and a clutch actuator including an output rod displaced by an actuator and a master cylinder generating a hydraulic pressure therein by closing an idle port communicating with a reservoir by a displacement of the output rod; a slave cylinder in communication with the master cylinder through a communication passage and operated by the hydraulic pressure generated by the master cylinder to operate the clutch device to be in engagement state or in disengagement state; characterized by a clutch engagement state holding control portion (steps 106 and 112) for holding the clutch device to be temporarily in engagement state by operating the master cylinder to be moved in an idle port opening direction when the disengagement state of the clutch device continues for a predetermined time period. an automated manual transmission which transmits a rotation of an input shaft adapted to be rotated by an engine torque outputted from an engine mounted on the hybrid vehicle to a drive wheel (16a, 16b) of the vehicle by changing a rotation speed of the input shaft to a plurality of speed stages with a plurality of speed change ratios; a motor connected to the drive wheel (16a, 16b) of the vehicle; a clutch device for engaging the output shaft of the engine with the input shaft of the automated manual transmission or disengaging the output shaft of the engine from the input shaft of the automated manual transmission and controlling a clutch torque transmitted to the input shaft of the automated manual transmission from the output shaft of the engine to be a target clutch torque; and a clutch actuator including an output rod displaced by an actuator and a master cylinder generating a hydraulic pressure therein by closing an idle port communicating with a reservoir by a displacement of the output rod; a slave cylinder in communication with the master cylinder through a communication passage and operated by the hydraulic pressure generated by the master cylinder to operate the clutch device to be in engagement state or in disengagement state; characterized by a clutch engagement state holding control portion (steps 106 and 112) for holding the clutch device to be temporarily in engagement state by operating the master cylinder to be moved in an idle port opening direction when the disengagement state of the clutch device continues for a predetermined time period.
