ABSTRACT:
Electric-motor drive control means controls a clutch engaging/disengaging actuator including two electric motors. When a vehicle starts moving or changes gears, the electric-motor drive control means drives both of the two electric motors in drive modes that require high responsiveness from an automatic clutch device and drives the two electric motors alternately in other drive modes that do not require high responsiveness. Malfunctions of the electric motors are detected during the operation. When one of the electric motors malfunctions, a warning is issued and the actuator is driven with the other electric motor that is normal. When both of the electric motors malfunction, a warning prompting a driver to stop the vehicle is issued.
