An electromagnetic clutch control device for vehicles, comprises clutch current calculation means (2) for outputting a clutch current command signal (SI) and a clutch disengaging signal (S0) based on running control information (DD) and engine control information (SE); a reverse energization resister (18) arranged between a power source (3) and a clutch coil (41) of an electromagnetic clutch (4) for the vehicle with the control device; clutch current control means (1) for controlling the supply of a clutch current to the electromagnetic clutch (4) based on the clutch current command signal (SI) and the clutch disengaging signal (S0), the clutch current control means (1) including the reverse energization resister (18); and switching means (22) which is subjected to the on and off control by the clutch current calculation means (2), and which is arranged to be in series with the reverse energization resister (18); wherein the switching means (22) is in the form of a reverse energization transistor to which a signal (SR) is supplied for only a predetermined period when means (2) determines the clutch should be disengaged, thereby allowing a minute reverse current to flow in the reverse energization resister (18). <IMAGE> |
