Method for Operating a Brake System of a Motor Vehicle, and Control Device and Brake System

A method for operating a brake system of a motor vehicle includes actuating a first actuating device of the brake system, exerting an electromechanical braking force to decelerate the motor vehicle in an event of a fault in the hydraulic braking device and when the first actuating device is actuated, and generating the electromechanical braking force after a start of the actuation of the first actuating device for a minimum generation period and/or generating the electromechanical braking force after an end of the actuation of the first actuating device for an additional continued generation period. The brake system includes a hydraulic braking device, an electromechanical braking device, and a first actuating device, in particular a brake pedal.
