SYSTEMS AND METHODS FOR PRESSURE CONTROL MIXED MODE FOR BRAKING OPERATION

A brake control system, comprising: a servo valve (421, 42r) configured to receive a hydraulic fluid and provide the hydraulic fluid to apply braking force to a wheel via a hydraulic line; and a brake control unit (150) in electronic communication with the servo valve; wherein the brake control unit is configured to: calibrate the servo valve; determine whether a calibration of the servo valve was successful; in response to the calibration of the servo valve being successful, operate the servo valve in an open-loop system; and in response to the calibration of the servo valve being unsuccessful, operate the servo valve in a closed-loop system.
