A method for operating a braking system, having a front and rear axle, the braking system including: a brake booster having a brake input element, coupled to an actuating travel sensor for providing a signal of a braking input; a brake master cylinder coupled to the brake booster coupled to a brake medium reservoir; fluid lines, in fluidic communication with the brake master cylinder and the brake medium reservoir, and with braking devices of the wheels via a system of valves, each of the wheels being coupled to a generator generating a braking torque, the method including: generating a hydraulic free travel with the valves and controlling valves with a control unit, a hydraulic pressure build-up for decelerating a wheel speed being prevented by generating free travel during actuation of the brake input element; and generating a regenerative braking torque for decelerating the wheel speed, based on the braking input.

Method and device for operating a braking system

A brake actuation recognition device has an evaluation device by which at least one provided modification quantity relating to a temporal change in an actual quantity relating to a pressure in a pressure chamber of a brake booster of a brake system is compared with a specified comparison quantity range such that, if the at least one provided modification quantity is within the comparison value range, it is determined that a brake actuating element situated on the brake system is in an actuation state below a specified minimum actuation state, and a corresponding information is outputted.
