  • Patent number: 9169007
    Abstract: The invention relates to a method of managing parking braking in a braking system for a vehicle fitted with at least one electric brake including at least one electric actuator having a pusher actuated by an electric motor for selectively applying a force against friction elements of the brake, the method comprising the steps of: establishing a series of direct adjustment tables for parking braking, corresponding to braking situations at different energy levels; when applying parking braking, selecting a direct adjustment table corresponding to a braking situation preceding the application of parking braking; and directly adjusting a parking braking force in application with the selected direct adjustment table.

  • Patent number: 8688341
    Abstract: A braking system for an aircraft with electric brakes comprising plural electromechanical actuators (2). The system comprises a braking control unit (20) delivering a normal braking setpoint (21) for one or more controllers (10) of the actuators, and selection logic (15) for causing the braking system to operate in a plurality of modes. The system includes: a normal braking mode where the control unit generates a normal braking setpoint (21) for the controller(s); an ultimate braking mode, having priority over the normal braking mode, being responsive to a parking control member, and controlling actuators to respond to the actuation of the parking control member; and a parking braking mode, applied in response to the parking control member and only if the aircraft is stationary, in which the actuators are controlled to apply a force in response to the parking control member being actuated and are then blocked in position.

    Abstract: A braking system for an aircraft with electric brakes comprising plural electromechanical actuators (2). The system comprises a braking control unit (20) delivering a normal braking setpoint (21) for one or more controllers (10) of the actuators, and selection means (15) for causing the braking system to operate in a plurality of modes. The system includes: a normal braking mode where the control unit generates a normal braking setpoint (21) for the controller(s); an ultimate braking mode, having priority over the normal braking mode, being responsive to a parking control member, and controlling actuators to respond to the actuation of the parking control member; and a parking braking mode, applied in response to the parking control member and only if the aircraft is stationary, in which the actuators are controlled to apply a force in response to the parking control member being actuated and are then blocked in position.

  • Publication number: 20120273309
    Abstract: An aircraft braking system architecture having brakes with electromechanical actuators (3) for selectively applying a braking force to respective stacks of disks (2) in order to exert a braking torque on respective wheels. Included is at least one power module (7) that sends phase currents to the electromechanical actuators so that the latter can exert a braking force and at least one control module (8) for controlling the power module in response to a braking command such that appropriate phase currents are sent to the actuators so that these can develop the desired braking force. At least one power supply unit (20), comprising means (21) of generating a high voltage (HVDC), supplies the power module with the high power it needs for powering the actuators. The unit (20) also has means (22) for generating a low voltage (LVDC) for powering at least the control module at a low voltage.

  • Publication number: 20110079471
    Abstract: The invention relates to an aircraft braking circuit having brakes with electromechanical actuators for braking wheels located at the bottom end of at least one undercarriage. In accordance with the invention, a remote unit is located at the bottom of the undercarriage close to the actuators and connected to a certain number of said actuators, the remote unit receiving a power supply via a power supply cable going down along the undercarriage, and having as many controlled switches as connected actuators for selectively powering blocking members fitted to the connected actuators, the switches being controlled independently of one another by software parking orders generated by a control unit and passing via a single communications bus going down along the undercarriage to the remote unit.
