Abstract:
A method for determining a transverse acceleration value (AQ) for control of an automatic transmission of a motor vehicle when a dynamic tire radius of a vehicle wheel diverges from an optimum tire geometry radius, comprising the steps of:determining an actual standardized wheel speed difference (NNDO) of two wheels of the vehicle, determining a corrected standardized wheel speed difference (NND) of the two wheels by correcting the actual standardized wheel speed difference (NNDO) by a previously determined time filtered standardized wheel speed difference (NNDF), and determining a transverse acceleration value (AQ) from the corrected standardized wheel speed difference and a factor for calculation of the transverse acceleration value (AQ) in a curve, the factor including a dynamic tire radii of the wheels.
