Speed sensor fault diagnosis and processing method
ActiveCN107782917AReduce the risk of misdiagnosisReduce the chance of false positivesTesting/calibration of speed/acceleration/shock measurement devicesDrive wheelDiagnosis methods
The invention provides a vehicle speed sensor fault diagnosis and processing method. When a vehicle speed sensor has an electrical fault, an electrical fault diagnosis method is used to diagnose the fault; for faults other than the electrical fault, a vehicle speed sensor of a driving wheel is mainly utilized to sense the wheel speed as a basis for diagnosing the vehicle speed sensor, by judging validity of the wheel speed and checking whether the average wheel speed is greater than the rotating speed of the vehicle speed sensor in low precision areas, wheel speed invalid areas and the low precision areas of the vehicle speed sensor are screened separately to reduce the vehicle speed misdiagnosis risk; through offline precision verification of an average wheel speed signal of a driving wheel, a fault judgment threshold is reasonably matched so as to reduce the false alarm probability of the vehicle speed sensor fault, and thereby the relatively reasonable final vehicle speed is acquired. The method is advantaged in that the application scope is wide, reliability of the diagnosis result is high, and actual demands can be satisfied.
