Method for operating a braking system of a motor vehicle, control device and motor vehicle

Abstract

Method for operating a braking system of a motor vehicle, comprising a friction brake device and a recuperation brake device, in which the cleaning requirement of the respective wheel brakes of the friction brake device of the motor vehicle is determined (V1), a deceleration of the motor vehicle desired by the driver is determined based on the position of a brake pedal mechanically decoupled from the friction brake device, and a braking force required for the desired deceleration of the motor vehicle is determined (V2), wherein a first, predetermined part of this braking force is distributed to the recuperation brake device and the remainder of the required braking force is distributed to the wheel brakes of the friction brake device (V3), wherein the braking force to be provided by the friction brake device is distributed to the wheel brakes depending on the determined cleaning requirement of the respective wheel brakes, wherein - the braking force distributed to the wheel brakes of the friction braking system is distributed to the wheel brakes depending on at least one predetermined stability criterion that must be met, and / or - when an anti-lock braking system and / or an electronic stability control system intervenes as vehicle dynamics control systems in the vehicle dynamics, the distribution of the braking force between the recuperation braking system and the friction braking system and / or between the wheel brakes is determined by the vehicle dynamics control system, and / or - when the first predetermined part of the braking force is selected to achieve the maximum possible recuperation power of the recuperation braking system.
