  • Patent number: 12122344
    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.

  • Patent number: 12115962
    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.

  • Patent number: 8886848
    Abstract: A method for assigning addresses in a system having a first generator unit and at least one further generator unit positioned in parallel to the first generator unit. Each of the generator units has a control-signal input and a control-signal output. The control-signal input of each further generator unit is connected in each instance to the control-signal output of another of the generator units. Each of the further generator units receives an identification signal output at the control-signal output of a generator unit upstream of it, and assigns itself an individual address as a function of the respective identification signal received, the address depending on the length of the identification signal received.
