    Abstract: An electronic brake system for a vehicle may comprise an electromechanical actuator (EMA) arrangement located at a first location and comprising an EMA and a transmitter unit, and an electronic brake actuator controller (EBAC) located at a second location remote from the first location and comprising a receiver. The transmitter unit is configured to receive an analog sensor signal, convert the analog sensor signal to a digital sensor signal, and send the digital sensor signal to the receiver.

    Abstract: A system for multi-mode autobrake control may comprise a wheel speed sensor and a BCU electrically coupled to the wheel speed sensor. A tangible, non-transitory memory may be configured to communicate with the BCU and may have instructions stored thereon that, in response to execution by the BCU, cause the BCU to perform operations comprising receiving a wheel speed signal from the wheel speed sensor, inputting the wheel speed signal into an antiskid filter and a nominal filter, calculating an estimated aircraft deceleration rate, and determining an autobrake pressure command based on the estimated aircraft deceleration rate.

    Abstract: A braking system is disclosed. In various embodiments, the braking system includes a brake stack; an actuator configured to apply a compressive load to the brake stack; a servo valve coupled to a power source and to the actuator; and a brake control unit configured to operate the servo valve at a current ramp rate in response to a pedal deflection signal, wherein the current ramp rate is determined via a relationship between the current ramp rate and a brake pressure command signal.

    Abstract: An antiskid controller for controlling braking operation of a wheel of a vehicle based on an output signal provided by a wheel speed sensor coupled to the wheel may comprise a delay toggle, a switch logic for switching between an initial rate and a running rate, and a linear control used for calculating an antiskid correction signal, wherein the linear control receives one of the initial rate and the running rate, depending on a state of the switch logic. The linear control receives the initial rate upon initialization of the antiskid controller. The linear control receives the running rate after a predetermined duration or after the linear control has converged on a desired solution.

    Abstract: Apparatus and associated methods relate to controlling a brake mechanism during braking operation to provide near-maximal braking power. Maximal braking power occurs at when the wheel slip has a target value. Wheel slip can be monitored during braking operation so as to be used in control the brake mechanism to operate at the maximal braking power. The braking power is modulated so as to dither the braking power about a nominal braking power. The monitored wheel slip will have a dither component in response to the dithering of the braking power. A volatility of the dither component of the monitored wheel slip can be indicative of nominal braking power proximity to the maximal braking power. A nominal brake signal can be generated so as to change the nominal braking power in the direction of the maximal braking power based on the volatility of the dither component of the monitored wheel slip.
