A method for operating a brake system of a motor vehicle. The brake system includes a master brake cylinder operable by a user and a pressure generator driven by an electric motor, for generating a hydraulic system pressure, and includes at least one hydraulically operable friction brake. On the inlet side, the at least one friction brake is assigned a proportioning valve acted upon by the system pressure, to adjust a hydraulic actuating pressure for the friction brake. The pressure generator is given a setpoint value for carrying out a testing operation. The setpoint value is selected so as to be smoothed by a logistical growth function.

Method and device for operating a brake system of a motor vehicle, brake system, and motor vehicle

A method for ascertaining a leakage in a hydraulic braking system of a motor vehicle, the braking system including at least one hydraulically actuatable wheel brake, at least one pressure generator and at least one discharge valve which is assigned to the wheel brake and actuated as a function of a driving situation of the motor vehicle to maintain driving stability, and a hydraulic volume of the braking system being monitored. It is provided that the leakage is ascertained as a function of the ascertained hydraulic volume and as a function of an actuation of the discharge valve.
