  • Patent number: 11780569
    Abstract: The invention relates to a method for controlling an aircraft taxi system, comprising the steps of: generating a traction command (Com) to control an electric motor of a wheel drive actuator; detecting whether or not an external brake command, intended to control braking of the wheel via the brake, is generated; if an external braking command is generated, producing a predetermined minimum command (Cmp) to control the electric motor so that the drive actuator applies a strictly positive predetermined minimum motor torque to the wheel during braking; detecting whether a speed of the aircraft becomes zero and, if so, inhibiting the predetermined minimum command (Cmp) so that the drive actuator applies zero torque to the wheel.
    Type: Grant

  • Patent number: 9057342
    Abstract: The invention relates to a system for controlling a plurality of actuators (15) that can displace a mobile panel (13, 17) pertaining to a nacelle (1) of an aircraft, said system comprising at least two motors (16) that can drive the actuators (15). The system also comprises two separate control units (33, 35), each unit being configured in such a way as to control and feed at least one motor that is not fed or controlled by the other control unit. The invention also relates to a nacelle comprising such a system.
