DEVICE FOR CONTROLLING AUTOMATIC MOTOR VEHICLE CLUTCHES

摘要

A device controls an automatic motor vehicle clutch (1) arranged between the driving motor (2) and a gearbox (3) and acting mainly as a starting clutch. A controlling device (5) converts an electric signal generated by an electronic controller (6) into a control value for a setting device (4) that opens and closes a clutch (1). The clutch (1) closure on starting occurs at a base engagement speed (VKG) dependent on the position of the accelerator pedal (7) and determined by an electronic controlling device (6) as an electric signal generated by this adjustment. To this effect, a characteristic line (A) specific to the motor is stored in the memory of the electronic controlling device (6), so that a base engagement speed (VKG) can be deduced very quickly and easily from the setting angle of the accelerator pedal (7). Correction factors (K1, K2) multiplied by the base engagement speed allow the quality of the clutch engagement to be further improved. Very stringent requirements imposed on a clutch can be met by setting the clutch again in the ''open'' position shortly before the synchronisation pooint (S) is reached. The opening moment and speed are equally included in the characteristic lines (D, E).
