First Claim
Patent Images
1. A method for the predictive determination of the change in the yaw rate (ψ
- ) of a vehicle, characterized in that the progress of the build-up of the braking pressures (p1 to p4) on the wheel brakes is monitored and that the yaw rate (ψ
) of the vehicle is determined predictably before a rotation of the vehicle around its vertical axis occurs.

Abstract
The invention relates to a method for the predictive determination of the change in the yaw rate (ψ) of a vehicle. According to said method, the progress of the build-up of the braking pressures (p1 to p4) of the wheel brakes is monitored, and the change in the yaw rate (ψ) of the vehicle is determined in a predictive manner from the progress of the pressure build-up before the vehicle rotates around the vertical axis thereof. The inventive method allows the driving stability of a vehicle to be better regulated.
