Abstract
A system for controlling an electromagnetic clutch for an infinitely variable belt-drive transmission, which is provided with an accelerator pedal switch for producing an output signal at release of an accelerator pedal of a vehicle, and a vehicle speed detector for producing an output signal at a low vehicle speed. The system is arranged to produce a small drag current signal in dependency on the accelerator pedal release signal and the low vehicle speed signal, so that a small drag clutch current flows in a coil of the electromagnetic clutch.
