  • Patent number: 11400901
    Abstract: A method for operating a vehicle, the vehicle including at least one friction brake unit, including a brake body and at least one brake element, the brake body being rotatably fixedly connected to a wheel of the vehicle and the brake element being situated on the chassis side and being displaceable in the direction of the brake body. The brake element is pressed against the brake body for generating a friction braking action, and an actual vehicle parameter resulting from the friction brake action being monitored for vibrations with the aid of at least one sensor unit. When detecting a vibration, the frequency of the vibrations is compared with the rotational speed of the wheel, and at least one safety measure is carried out in a third step if the comparison indicates that the frequency is equal to or greater than the rotational speed of the wheel.

  • Patent number: 11254295
    Abstract: An automatic braking device for a vehicle and a method for automatically braking a vehicle. The vehicle is automatically braked using at least one friction brake of the vehicle in such a way that a brake force that is effectuated by the at least one friction brake is increased, at least at times, with a predefined maximum brake force buildup gradient and/or up to a predefined maximum brake force. At least when no emergency braking situation is present, it is ascertained prior to the automatic braking whether the vehicle at that moment is traveling through a specified or self-determined particulate matter protection area, and, if necessary, the brake force that is effectuated with the aid of the at least one friction brake is increased at most with a predefined or set limiting brake force buildup gradient and/or at most up to a predefined or set limiting brake force.

  • Patent number: 11247678
    Abstract: A method for operating a motor vehicle having partial/full autonomous driving, having a plurality of wheels, a drive system for producing a drive torque at at least one of the wheels, and a brake system for producing at least one holding force for holding still at least one of the wheels, a rotational speed sensor being allocated to at least one of the wheels, which sensor produces a respective signal pulse for each of a plurality of positions of angular rotation of the associated wheel, a specifiable driving maneuver being performed as a function of the produced signal pulses. For a short path driving process starting from a standstill, the brake force is reduced until the rotational speed sensor produces a first signal pulse, and is then held at least temporarily constant until a specified number of signal pulses is produced, and subsequently is increased up to the holding force.

  • Publication number: 20200023823
    Abstract: In a method for generating braking power by actuating at least one electric braking motor in a vehicle parking brake comprising two control devices, in the event of a failure of a first control device/braking motor unit, braking power is generated automatically via a second control device/braking motor unit if the vehicle speed is lower than a threshold value and/or if a characteristic value in the vehicle (e.g. the ignition status) indicates that the vehicle is at or is about to come to a standstill, but preferably only once a defined time interval has elapsed.
