ABSTRACT:
A generator system includes an alternator driven by an engine through a driving belt and an electronic control unit for controlling operation of the engine. The alternator and the engine is coupled by a driving belt through a one-way clutch that transmits the engine torque to the alternator and intercepts torque transmission from the alternator to the engine. A malfunction in the one-way clutch is detected, under a condition where the engine speed is decreasing, by comparing a rotational speed of its inner ring connected to the alternator with a rotational speed of its outer ring coupled to the engine through the driving belt. The malfunctioning one-way clutch is either replaced or repaired, to thereby avoid damages of the driving belt caused by the clutch malfunction.
