Abstract

First and second signals representing unevenness of the roadway are generated for at least one wheel, and brake pressure is controlled using control parameters based on the second signal. The first signal is compared to a first threshold which is dependent on the second signal, and an extreme value signal which represents large impacts on the vehicle is generated when the threshold is exceeded. The control parameters are then adjusted so that the channels for controlling brake pressure at each controlled wheel are less sensitive.
