SYSTEM FOR CONTROLLING THE CLUTCH TORQUE OF AN ELECTROMAGNETIC CLUTCH FOR A VEHICLE

摘要

A vehicle with an electromagnetic clutch (1) has an accelerator pedal switch (15) which produces a given output signal when an accelerator pedal of the vehicle is depressed. A clutch current circuit (18 - 20) includes a transistor (20) and controls the clutch current passing through the coil (6) of the electromagnetic clutch (1). When the vehicle speed is above a predetermined value, as determined by a switch (16), a logic gate circuit (31) responds to the given output signal of the accelerator pedal switch (15) to control the transistor (20) so as to decrease the clutch current to a low value and thereafter to gradually increase the current to a predetermined value.
