  • Patent number: 12168431
    Abstract: A brake system for a motor vehicle has electromechanical wheel brakes, a brake operating unit and a central brake control unit. The wheel brakes each have a local brake control unit. The central brake control unit is connected to the brake operating unit and the local brake control units via a first data connection. The brake operating unit is connected to the local brake control unit of at least one wheel brake via a second data connection. In a normal operating mode the central brake control unit determines at least one brake demand from first operating information, received via the first data connection and transmits control signals corresponding to the brake demand to the local brake control units. In a fallback operating mode the local brake control units actuate the respective wheel brakes basis on second operating information, received via the second data connection.

  • Patent number: 12097834
    Abstract: A method for determining an operating variable of a drum brake comprises actuating the brake in at least one of: a first wheel speed range and a second wheel speed range. The operating variable is calculated based on bearing force of a leading brake shoe and the further bearing force of a trailing brake shoe when in the first wheel speed range. The operating variable is calculated when in the second wheel speed range based on a current actuator position and an actuator contact position, in which brake shoes of the drum brake come into engagement with a drum of the drum brake.

  • Patent number: 12019171
    Abstract: A method for determining the position of a vehicle is disclosed. GNSS signals from a global satellite navigation system are received by a receiving device. A vehicle velocity is detected; and a check is carried out as to whether the detected vehicle velocity falls below or exceeds a threshold value. After the vehicle velocity falls below the threshold value, the position of the vehicle is determined on the basis of a first calculation method. After the vehicle velocity exceeds the threshold value, the position of the vehicle is determined on the basis of a second calculation method. Both calculation methods include filtering the GNSS signals by a fusion algorithm. The calculation methods differing by input variables of the fusion algorithm.

  • Patent number: 11964644
    Abstract: A method for operating a motor vehicle brake system having hydraulic wheel brakes; an atmospheric pressure pressure medium reservoir; a pressure modulation unit setting wheel-specific brake pressures, an electrohydraulic pressure provision device connected to the pressure modulation unit and the pressure medium reservoir which outputs brake system pressure to the pressure modulation unit and draws in pressure medium from the reservoir; a first and second pressure activation valve connecting the pressure provision device to the pressure modulation device. A piston of the piston-cylinder arrangement separates two pressure spaces from one another. A pressure build-up occurs in the first pressure space during a backward movement of the piston and in the second pressure space during a forward movement of the piston. During a brake pressure build-up by a forward stroke of the piston, the activation valve is opened and the first pressure space is hydraulically separated from the pressure medium reservoir.
