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.

Electronically programmable method for improving the control behavior of an anti-lock braking control system

To improve the control behavior of a brake system with anti-lock control (ABS) on the occurrence of road irregularities, a brief braking pressure reduction phase with a major braking pressure reduction on a wheel, followed by a high re-acceleration of the wheel, is interpreted as a road irregularity if the quotient of the duration of the braking pressure reduction and of the total duration of the pressure reduction phase multiplied by the re-acceleration of the wheel or the maximum value of the re-acceleration or if the acceleration variation or the maximum value of the acceleration variation exceeds predetermined limit values, and a braking pressure rise that is increased compared to the standard ABS control is caused as a result of detection of the road irregularity.
