Abstract: A brake system is disclosed herein. The brake system includes a motor, a hydraulic pump mechanically coupled to the motor, a directional control valve fluidly coupled to the hydraulic pump, and a brake assembly fluidly coupled to the directional control valve. The directional control valve is moveable between a braking position, in which the directional control valve allows hydraulic fluid to flow between the hydraulic pump and the brake assembly, and a parking position, in which the directional control valve prevents the hydraulic fluid from flowing between the hydraulic pump and the brake assembly.

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.
