METHOD FOR MONITORING AT LEAST TWO ELECTROMECHANICAL BRAKING ACTUATORS

摘要

A method for monitoring at least two aircraft wheel electromechanical braking actuators. For each electromechanical actuator, the method includes first determining a current value representative of the power supply current of the electromechanical actuator and determining a reference current value estimated from the power supply currents of at least one other electromechanical actuator. Then, the representative current value and the reference current value are compared. Any abnormal operation of the electromechanical actuator is detected when the difference between the representative current value and the reference current value is above a predetermined threshold.

1. A method for monitoring at least two aircraft wheel electromechanical braking actuators (5), each electromechanical actuator (5) being powered by means of a power supply current (Ia) to selectively apply a braking force to friction members (15), the monitoring method comprising the step of activating the electromechanical actuators (5), and, for each electromechanical actuator (5), the steps of:
determining a current value (Ivr) representative of the power supply current of the electromechanical actuator; determining a reference current value (Ir) estimated from the power supply currents of at least one other electromechanical actuator (5); comparing the representative current value and the reference current value; detecting an abnormal operation of the electromechanical actuator (5) when the difference between the representative current value and the reference current value is above a predetermined threshold (Is).
