Abstract
Disclosed is a method of controlling the driving dynamics of a vehicle, in which a nominal value ({dot over (ψ)}ref) of a driving state variable that corresponds to a preset driver input is compared with a detected actual value ({dot over (ψ)}) of the driving state variable, and in which a rolling moment distribution is detected and modified. The method is implemented in such a manner that the driving performance of the vehicle is determined by comparing the nominal value ({dot over (ψ)}ref) of the driving state variable with the actual value ({dot over (ψ)}) of the driving state variable. Also, depending on the determined driving performance, a new rolling moment distribution is determined which corresponds to a predefined driving performance and the new rolling moment distribution is adjusted.
