VALIDATION DEVICE FOR A BRAKE FLUID PRESSURE SENSOR AND METHOD OF DETERMINING THEREOF

摘要

A validity determination device for a brake fluid pressure sensor and a determination method therefor are disclosed. According to an exemplary embodiment of the present disclosure, the brake fluid pressure sensor validity determining apparatus and the determination method thereof include an input device configured to receive a brake fluid pressure sensor value detected by a brake fluid pressure sensor and to receive a motor position sensor value that is from a brake fluid pressure sensor An engine position sensor has been detected, an estimator configured to estimate a brake fluid pressure value based on the engine position sensor value when the engine position sensor has not failed; and a determination device configured to determine whether the brake fluid pressure sensor has failed, determine whether the engine position sensor has failed, if 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.
