TRACTION-SLIP CONTROL METHOD WITH THEORETICAL TRANSVERSAL ACCELERATION AND CONTROL CIRCUIT FOR CARRYING OUT SUCH A TRACTION-SLIP CONTROL METHOD

摘要

The invention relates to a traction-slip control for a motor vehicle in which a traction-slip control phase is activated for a driving wheel in accordance with a control strategy if its traction-slip exceeds a predetermined slip threshold value (Ssw). The inventive method is characterized in that a transversal reference acceleration is determined for an expected cornering course, that an actual transversal acceleration is determined, that a difference between the transversal reference acceleration ay-ref and the actual transversal acceleration a¿y-actual? is calculated, and that it is determined whether said difference exceeds a threshold value. If said difference exceeds the threshold value, the control strategy is modified in such a manner that a higher torque can be produced at least at two wheels than if said difference does not exceed the threshold value. The invention further relates to a control circuit that is suitable for carrying out the inventive method.
