The invention relates to a method for improving the control behavior of an electronic motor vehicle braking system which comprises at least a slip control function. Wheel dynamic information which is evaluated as a criterion for initiating a control intervention is used individually for each wheel and is compared with control thresholds for a pressure reduction phase, a pressure maintenance phase, and a pressure buildup phase for generating corresponding braking torques by means of a vehicle braking system. According to the invention, the expected acceleration change of a vehicle wheel is calculated from a pressure change at said wheel, said pressure change being caused by a control intervention; the actual acceleration change at the vehicle wheel, said acceleration change being caused by the pressure change, is determined from measured wheel speeds as wheel dynamic information; and the control behavior of the slip control is adapted when the actual acceleration change deviates from the expected acceleration change by a defined degree such that the deviation is minimized.

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.
