Method for improving the control behavior of a controlled vehicle braking system

A method for improving the control behavior of a controlled automotive vehicle system,

• 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),
• wherein evaluation parameters (α,β) that can be modified in response to driving conditions are determined and taken as a reference in the evaluation of the wheel dynamics data (dyn) and in the evaluation of the wheel slip data (slip),
• wherein the evaluation parameters (α,β) are modified in dependence on a longitudinal force prevailing between tires and roadway,
• wherein one of said evaluation parameters (β) is associated with wheel dynamics (dyn) of the wheels of a rear axle (RA) of the vehicle, and wherein said evaluation parameter (β) assumes a substantially constant value for longitudinal forces categorized as transitional and great, and is greater than said substantially constant value for longitudinal forces categorized as low (a).
