  • Patent number: 12643511
    Abstract: The clamping strategy of an electromechanical brake depends on an already existing hydraulic pressure, in order to adjust the mechanical component of the clamping force and avoid an excessive clamping of the brake. The hydraulic component (FHyd) of the clamping force is estimated according to a pressure measurement, subtracted from a target force (FTar) to obtain the mechanical component to be applied (FTarNew), and the electric motor for controlling clamping of the brake is stopped at a threshold value (I2) of the current that is supplied thereto, according to the value of this mechanical component to be applied.

  • Patent number: 12617381
    Abstract: A motor vehicle braking system including at least one electrically actuated parking brake (FP) to be positioned at a wheel, a control unit (UC) configured for generating a command for the parking brake (FP) to apply parking braking or to interrupt the application of parking braking at a first intensity following a first request, wherein the control unit (UC) is also configured for generating a command for the parking brake (FP) to apply parking braking at a second intensity in response to a second request issued after the first request.

  • Patent number: 12567818
    Abstract: The releases of an electromechanical parking brake are controlled by measuring the change in the intensity (I) of the electrical current provided to the control motor, or a function derived from this intensity, and by extending the release of the brake only for a determined duration (?t) after stabilization of this intensity, in order not to unnecessarily increase the idle travel of the brake actuator nor to extend the duration of the control. The determined duration (?t) also depends on the temperature and on the hydraulic pressure in the brake.

  • Publication number: 20250001992
    Abstract: An electromechanical parking brake command is aborted with no predefined plan being completed if the driver initiates an opposite command when the vehicle is stationary. The plan normally implemented for the second command is itself shortened as a result. The brake is therefore quickly returned to its original state, and a command sent inadvertently is corrected quickly.
