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.

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.

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.

Method for operating a brake system, and brake system

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.

Method for estimating the locking pressure in the brake system of a multi-axle vehicle

A method for controlling and/or regulating an electronically triggerable vehicle brake system, operating on the return principle, and to such a brake system in which by an adapted triggering of the drive motor for the pressure generator, the pumping quantity of the pressure generator is varied such that the difference between these flows of pressure medium to and from the master cylinder assumes a minimal value, preferably a value of zero. To that end, the driving rpm of the pressure generator is preferably varied. The trigger signal for the drive motor can be ascertained by an electronic control unit from measurement outcomes from sensors within the vehicle brake system, or it can be estimated with the aid of a hydraulic volume model stored in memory in the control unit. The trigger signal can be controlled or regulated.

A method for determining a variable representing a hydraulic pressure drop across a valve of a brake circuit, in which a control pulse, designed such that abrupt braking pressure changes are suppressed, is applied to the valve, and in which the hydraulic pressure drop across the valve is determined from the knowledge of the control pulse.

Only the brake pressures at the front wheels are controlled individually. For this purpose, the speeds of rotation of the front wheels are detected. The brake pressure at the rear wheels is controlled jointly for both rear wheels and no detection of the speed of rotation is provided at the rear wheels. However, the brake line leading to the rear-wheel brakes has inserted into it a 2/2-way valve which can be moved into its shut-off position as a function of the brake-force distribution determined as a function of the loading and then holds the rear-axle brake pressure constant.

Anti-lock control with rear brake pressure limitation

A system for changing the damping characteristics of shock absorbers, based on the signals (Xar'(t)) of the relative movements such as the spring deflection velocity, between the vehicle superstructure and wheels, additional signals (Xar'(t)), such as the spring deflection acceleration, are determined. The two signals are logical linked so that the control of a vehicle variable, such as the activation of adjustably designed shock absorbers, is carried out. This makes it possible to change the characteristic of the shock absorber in operating phases of low damping forces of the shock absorber. This feature optionally reduces noise at damping characteristic changes.

System for control of a vehicle chassis

Signals delta.sub.-- w representing the RPM difference of at least two wheels of at least one axle and signals V representing the vehicle speed are linked through a nonlinear characteristic diagram. Obtained thereby are signals which represent the transverse movements, specifically the transverse acceleration, of the vehicle. This makes it possible to allow for nonlinear effects such as the expansive deflection of the curve inside tires and the compressive deflection of the curve outside tires due to the roll moment backing, particularly through empirically determined parameters. The signal of the stationary transverse acceleration is dynamized by further processing, in a second order filter, of the signal of the stationary transverse acceleration (steering angle is constant) so obtained.
