Abstract:
A method for providing traction control for a motor vehicle operating on a curve of a road, the method comprising the steps of:recording, using at least one sensor, an acceleration in a transverse axis, a driving speed of the motor vehicle, a speed of a wheel and a radius of a curve of a road; determining a slip value of a wheel from recorded values; comparing the slip value with a predefined slip threshold; at least one of braking the wheel on an inside of the curve of the road upon exceeding the predefined slip threshold, and reducing a drive torque of an engine of the motor vehicle to limit a traction of the motor vehicle upon exceeding the predefined slip threshold; and changing the predefined slip threshold for the wheel on the inside of the curve of the road upon exceeding the predefined slip threshold, wherein the predefined slip threshold is determined as a function of the acceleration in the traverse axis according to a straight line equation of LAMB AY=OFF AY+AY FAK*AY, where OFF AY is a constant offset value and AY FAK is a slope parameter for the straight line equation.
