Abstract: Disclosed herein are a brake fluid pressure sensor validity determination device and a determination method thereof. According to an embodiment of the present disclosure, the brake fluid pressure sensor validity determination device and the determination method thereof includes an inputter configured to receive a brake fluid pressure sensor value sensed by a brake fluid pressure sensor and receive a motor position sensor value sensed by a motor position sensor, an estimator configured to estimate a brake fluid pressure value on the basis of the motor position sensor value when the motor position sensor has not failed; and a determiner configured to determine whether the brake fluid pressure sensor has failed, determine whether the motor position sensor has failed when the brake fluid pressure sensor has not failed, and determine a validity of the brake fluid pressure sensor by comparing the estimated brake fluid pressure value with a brake fluid pressure sensor value.

Abstract: Disclosed are an electric brake system and a control method thereof. The electric brake system includes a sensor part including at least three sensors among a motor position sensor MPS configured to measure a position of a motor, an acceleration sensor configured to measure a longitudinal acceleration of a vehicle, a wheel speed sensor configured to measure a wheel speed of the vehicle, and a pressure sensor configured to measure a brake hydraulic pressure of a wheel; and a controller configured to receive measured results from the at least three sensors among the motor position sensor MPS, the acceleration sensor, the wheel speed sensor, and the pressure sensor and determine that a sensor fails, which outputs a brake hydraulic pressure having a largest deviation among three or more brake hydraulic pressures that are estimated or measured from the at least three sensors.
