  • Actuating arrangement for a parking brake of a motor vehicle and motor vehicle having the actuating arrangement
    Patent number: 11738733
    Abstract: An actuating arrangement (1) for a parking brake of a motor vehicle, having a first actuating unit (5), for manual actuation of the parking brake, and a shaft (2) for transmitting braking forces (F1, F2) to at least one wheel brake cylinder (4) of a service brake of the motor vehicle. The first actuating unit (5) is operatively connected to the shaft (2) so that, when the first actuating unit (5) is actuated, a first braking force (F1) is transmitted via the shaft (2) to the at least one wheel brake cylinder (4). The actuating arrangement (1) has a second actuating unit (7) for the controllable actuation of the parking brake. The second actuating unit (7) is operatively connected to the shaft (2) so that, when the second actuating unit (7) is actuated, a second braking force (F2) is transmitted via the shaft (2) to the wheel brake cylinder (5).

  • Adaptive friction minimization for electrohydraulic actuators
    Patent number: 11378109
    Abstract: A method of controlling an electro-hydraulic actuator (101). An electric voltage applied to the actuator (101) is established by superimposing a control variable with an oscillatory signal. A hydraulic pressure, influenced by the actuator (101), is measured. The oscillatory signal is adapted as a function of the measured hydraulic pressure.
