Abstract
A method is provided for detecting an uncommanded brake overdrive condition in an aircraft brake control system. Method comprises monitoring, by an electric brake actuator controller (EBAC) in the brake control system, at least one of the following: a load cell current for deviation from a nominal load cell current and a load cell output signal (LC Sig+) and (LC Sig−) of a plurality of individual load cells and an excitation voltage signal comprising a (Vexc+) signal and a (Vexc−) signal. EBAC detects at least one resistance disturbance indicating the uncommanded brake overdrive condition if load cell current is less than nominal load cell current, if an absolute value of the difference between a sum of LC Sig+LC Sig− for at least one individual load cell and a sum of Vexc++Vexc− is greater than a predefined threshold, or both.
