Abstract:
An electromagnetic clutch control device for use with a vehicle, the vehicle comprising a generator connected to a drive wheel, a battery electrically connected to the generator, a conversion circuit which converts a power generated by the generator into a power stored by the battery, an engine and an electromagnetic clutch which transmits an output torque of the engine to the drive wheel under an engaging force according to an energizing current, the control device comprising:a sensor which detects an output rotation speed of the electromagnetic clutch;a sensor which detects that the vehicle is in a predetermined deceleration state; anda micro processor programmed to:supply the energizing current to the electromagnetic clutch; and increase the energizing current the lower the output rotation speed of the electromagnetic clutch, when the vehicle is in the predetermined deceleration state; andwherein the conversion circuit has a function to vary a power generation resistance of said generator according to a command signal, and the microprocessor is further programmed to control the command signal so that the power generation resistance of the generator coincides with a predetermined target regeneration torque.
