Abstract

The present invention relates to a method for improving the control behavior of a controlled automotive vehicle system, in particular an anti-lock brake system (ABS), a driving stability control system (ESP), or another brake system extended by other functionalities, wherein evaluated wheel dynamics data (dyn) and evaluated wheel slip data (slip) are taken into account as a criterion for the initiation of a control intervention for each individual wheel, and the sum thereof is compared to a control threshold (ψ).For a better weighting of wheel dynamics and slip, the invention discloses determining evaluation parameters (α, β) that can be modified in response to driving conditions and taking them as a reference in the evaluation of the wheel dynamics data (dyn) and in the evaluation of the wheel slip data (slip).
