Method for operating a brake system of a motor vehicle, control unit, and motor vehicle

A method for operating a brake system of a motor vehicle, comprising:

• determining a need for cleaning of respective wheel brakes of a friction braking device;
• determining a deceleration of the motor vehicle desired by the driver, based on (i) a position of a brake pedal that is mechanically decoupled from the friction braking device, and (ii) a braking force that is required for the desired deceleration of the motor vehicle;
• allocating a first, predefined portion of the braking force to a regenerative braking device and allocating a second, predefined portion of the braking force among wheel brakes of the friction braking device, wherein the braking force allocated among the wheel brakes of the friction braking device is allocated among the wheel brakes as a function of at least one predefined stability criterion;
• and
• distributing the braking force to be provided by the friction braking device among the wheel brakes as a function of the determined need for cleaning of the respective wheel brakes, wherein distributing the braking force comprises allocating different braking force portions to the wheel brakes based on respective determined cleaning needs of the wheel brakes, such that a wheel brake having a greater determined need for cleaning receives a greater portion of the braking force.
