Abstract: A method for operating a braking device of a vehicle, including a main braking system, and a backup braking system. The braking device includes a main braking system control unit, and a backup braking system control unit. The method includes detecting an error of a brake function of the braking system, locating the error inside the braking device, classifying the error with regard to the corresponding brake function and the braking system, and transferring a brake function detected as erroneous for the main braking system to the backup braking system in the event that the error concerns solely the main braking system, so that the brake function may still be carried out with the aid of the backup braking system.

Abstract: A method for operating a brake system of a vehicle, in particular, of a motor vehicle. The brake system includes at least one electric actuator, in particular, a brake booster, which may be driven to generate a braking force, the actuator being controllable by an autonomous driving system, and as a function of manipulation of a brake pedal of the vehicle; and an emergency braking action being initiated, when the actuator is driven both by the autonomous driving system and by manipulation of a brake pedal. The control by the autonomous driving system is superimposed with a varying validation signal, a differential travel between an actuator element of the actuator and the brake pedal is monitored, and the driving of the actuator via manipulation of the brake pedal during the control by the autonomous driving system is detected, if the differential travel varies.

Abstract: The method relates to a method for boosting the braking force in an electromotor operated slip-controllable vehicle brake system having electromechanical brake boosting. The vehicle brake system includes a braking-intention detection device, an electromechanically actuatable brake booster, and an electronically actuatable brake-pressure control device. In the event of a malfunction of the brake booster, the boosting of the brake pressure is alternatively assumed by the brake-pressure control device. In the event of a malfunction of the brake boosting, it is checked whether a generation and a transmission of a trigger signal representing the actuation of the braking-intention detection device from the first electronic control device of the brake booster to a second electronic control device of the brake-pressure control device is possible, and if this is so, the trigger signal is transmitted via an existing communications link between the control devices.

Abstract: A method for controlling a power brake system, for a motor vehicle engaged in piloted driving, which includes two electrically controllable actuator units. The first actuator unit includes a braking-intent detection device, and a first pressure generation unit for generating a brake pressure in a brake circuit. The second actuator unit includes a second pressure generation unit redundant to the first pressure generation unit. A first electronic control device acquires signals of the braking-intent detection device and controls the actuator unit based on the detected braking intent. In response to detected functional impairment, the first motor of the pressure generation unit ceases to be controlled, and the second motor of the pressure generation unit of the second actuator unit is controlled to generate brake pressure. Detection of a braking intent and wheel-specific modulation of the brake pressure, continue to be carried out, using devices of the first actuator unit.

Abstract: A method for ascertaining an available fluid volume in a tank for brake fluid of a braking system. The braking system includes a pressure generator fluidically connected to the tank on the one hand and to at least one brake circuit on the other hand, which is activatable for generating a hydraulic pressure in the braking system as brake fluid is withdrawn from the tank. A drop below a predefined limiting value for a fill level of the brake fluid in the tank is monitored with the aid of a binary sensor assigned to the tank. It is provided that an actuation of the pressure generator is monitored and that the available fluid volume is ascertained as a function of the actuation of the pressure generator when the instantaneous fill level drops below the limiting value.

Abstract: A hydraulic brake system, in particular a hydraulic brake system for a motor vehicle. The control of a master brake cylinder to build up the hydraulic pressure is effected exclusively by an electric drive. The setpoint specification for controlling the electromechanical drive can be received as an electrical signal. In the event of a fault, redundant brake pressure generation can be ensured by using a brake pressure generation device of a vehicle dynamics control system.
