Abstract: A method for detecting an erroneous velocity data using a controller in communication with a velocity sensor onboard a vehicle includes receiving a time-series velocity data from the velocity sensor, calculating a time-series acceleration data using the time-series velocity data, calculating a time-series jerk data using the time-series acceleration data, calculating a saturated (numerically bounded) jerk data using the time-series jerk data, calculating an estimated acceleration data using the saturated jerk data, calculating a difference between the estimated acceleration data and the time-series acceleration data, and determining whether the difference is greater than a threshold value. The erroneous velocity data is detected in response to the difference being greater than the threshold value.

Abstract: Systems and methods for reducing disturbances that may result from using gain scheduling in brake controls. This method may include the steps of detecting a control signal, comparing the control signal to a threshold value, and gradually increasing or decreasing a controller gain in response to amplitude of the control signal being above or below the threshold value.

Abstract: A brake wear monitoring system for measuring extended wear lengths includes a processing unit, a plurality of linear Hall sensors in electronic communication with the processing unit, a wear pin coupled to a brake stack, the wear pin comprising a magnetic portion, wherein the plurality of linear Hall sensors are configured to detect a position of the wear pin via the magnetic portion, and the processing unit is configured to generate an output signal, based upon the position of the wear pin relative to the plurality of linear Hall sensors, to indicate a wear status of the brake stack.
