Abstract
The present invention relates to a method for improving an anti-lock control system, in particular for improving driving stability during braking on laterally different coefficients of friction. According to the method, a desired yaw rate is determined using at least one steering angle signal of a steering angle sensor and an actual yaw rate is determined using at least one yaw rate sensor, and the instability is evaluated using a parameter that serves for a qualitative and quantitative judgment of a deviation between the actual yaw rate and the desired yaw rate. Both yaw rate deviation and the time derivative of the yaw rate deviation are used to determine the parameter.
Claims11
A method for improving an anti-look control system, in which the wheel rotational behavior is measured and taken into account for determining the wheel slip and for brake pressure modulation,
- wherein the method includes the steps of
- determining driving stability by using at least one steering angle signal of a steering angle sensor for determining a desired yaw rate (ωLW) and by using at least one yaw rate sensor for measuring an actual yaw rate (ωact), and
- evaluating the driving stability by way of a parameter (Θ) that is determined for qualitatively and quantitatively judging a deviation between actual yaw rate (ωact) and desired yaw rate (ωLW) by employing the measured actual yaw rate (wood and by employing a measured desired yaw rate (ωLW) and by employing the time derivative of the difference (Δ{dot over (ω)}) between actual yaw rate (ωact) and desired yaw rate (ωLW).
