Abstract: A method for operating a brake system of a motor vehicle. The motor vehicle has a vehicle body and multiple wheels mounted relative to the vehicle body by a wheel suspension on the vehicle body. The vehicle body is capable of executing a pitching movement by the wheel suspension. The brake system has a wheel-individual wheel brake for at least some of the wheels. A pitch angle of the vehicle body is monitored, and the wheel brakes are actuated as a function of the acquired pitch angle. The pitch angle is calculated as a function of normal forces acting on the wheels.

Abstract: A method for operating an antilock brake system of a vehicle, in which a braking torque at at least one wheel of the vehicle is cyclically controlled in at least build-up phases and reduction phases, in order to prevent locking of the wheel. In a build-up phase, the braking torque is increased until a maximum adhesion at the wheel is exceeded, and in a subsequent reduction phase, the braking torque is reduced by a differential braking torque, which is ascertained, using a wheel acceleration value of the wheel measured after the build-up phase and a target acceleration value for the wheel.

Abstract: In a method for estimating the locking pressure in the brake system of a multi-axle vehicle during a dynamic axle-load transfer, the locking pressure is ascertained during the axle-load transfer and the wheel normal force is ascertained at two points in time during the axle-load transfer and the locking pressure is ascertained therefrom at the later point in time.

Abstract: A method for operating a brake system of a vehicle. A precontrol value for a brake pressure of the brake system is set by using an admission pressure value representing a admission pressure in the brake system and a processing specification representing a braking dynamics of the vehicle.
