Abstract
A vehicle has a power extraction mechanism 8, 9, 10a, 10b, 10c, which transmits the rotation of the power transmission mechanism to the auxiliary machines 20, 21, a solenoid clutch 11, which enables or disables the transmission of rotation to the auxiliary machines by the power extraction mechanism, and a determination device 30, 31, 32, which determines whether a control system of the motor 22 for auxiliary machines is operating abnormally or normally. The solenoid clutch 11 is maintained in a disengaged state when the control system of the motor 22 for the auxiliary machines is operating normally. In contrast, when an abnormality is detected in the control system, the auxiliary machines are driven by the rotational force of the power transmission mechanism because the solenoid clutch 11 is engaged at that time. In this manner, it is possible to maintain normal operation of the vehicle by driving the auxiliary machines even when there is an abnormality in the control system.
