  • Patent number: 11936506
    Abstract: A system for transmitting a value via a pulse-width-modulated signal, comprises a transmitter and a receiver. The transmitter is configured for detecting the value and for outputting a pulse-width-modulated signal having a pulse width which represents the value or a range around the value. The receiver is configured for deriving the value or the range from the pulse-width-modulated signal, by evaluating the pulse width. The transmitter is furthermore configured to read back the emitted pulse-width-modulated signal and to check whether the value or the range can be derived from the emitted pulse-width-modulated signal, and, if the value or the range cannot be derived, to output an error signal to the receiver.

  • Patent number: 11370404
    Abstract: An electronically controllable braking system for a commercial vehicle is provided, including a service brake system having a front axle brake circuit with a front axle modulator, a rear axle brake circuit, and a central control module. The central control module is configured to implement a braking specification via the front axle brake circuit and the rear axle brake circuit. A parking brake module that is configured, in the event of a defect in the central control module, to process the braking requirement and to output a rear axle redundancy brake pressure to spring-brake parts for the redundant implementation of the braking specification. It is further provided that the front axle modulator is configured to process the braking specification and to output a front axle redundancy brake pressure to the front axle brakes for the further redundant implementation of the braking specification.

  • Patent number: 11320007
    Abstract: A method is disclosed for monitoring the functions of a friction clutch which is arranged in a vehicle between a drive motor and a compressor of a compressed air supply system and which can be disengaged and engaged pneumatically. In a delivery mode of the compressor, at least one operating parameter is detected by sensor and evaluated in an electronic control unit. When a slipping condition of the friction clutch is identified, a value for a cut-off pressure of the compressor stored in the electronic control unit is reduced. When a slipping condition has been identified, the delivery mode of the compressor is ended by disengagement of the friction clutch, and a warning signal and/or warning information is outputted.

  • Patent number: 11084470
    Abstract: A method for regulating a vehicle-actual-deceleration in a vehicle with an ABS brake system includes detecting the vehicle-actual-deceleration; determining a target vehicle deceleration and detecting at least one actual wheel rotational behavior. The method further includes calculating actuation times for actuation of pressure control valves of the ABS brake system associated with the wheels of the first vehicle axle and the wheels of the further vehicle axle and determining correction actuation times if at least one of the respective calculated actuation times is less than a minimum actuation time associated with the respective pressure control valve. Calculation of each of the respective actuation times is carried out at least for all of a first number of pressure control valves with which wheels are associated whose rotational behavior follows the at least one actual wheel rotational behavior.
