AUXILIARY MACHINERY DRIVER FOR CAR

摘要

In a car having a traveling motor serving as a car prime mover, and an auxiliary machinery motor for driving an auxiliary machinery, power take-out mechanisms (8, 9, 10a, 10b, 10c) for transmitting the rotation of a car power transmission mechanism to auxiliary machines (20, 21), an electromagnetic clutch (11), and judging means (30 to 32) for judging whether the control system of an auxiliary machinery motor (22) is normal or abnormal are provided. If the control system is judged to be normal, the electromagnetic clutch (11) is kept cut; if the control system is judged to be abnormal, the electromagnetic clutch (11) is kept in a connection state. Thus, the auxiliary machinery is driven by the torque of the power transmission mechanism. Therefore, in case the control system falls abnormal, the auxiliary machinery can be driven and the car can maintain its normal traveling.
