Abstract EN
This paper presents a sequential fault detection and identification algorithm for detecting a fault in a vehicle's ultrasonic parking sensors.
The algorithm identifies a bias fault in any of the ultrasonic sensors by computing the probability of having that bias fault given a carefully constructed measurement residual that is only a function of the measurement noise and the possible measurement fault.
A set of bias hypotheses is assumed and initially given equal alarm probability.
It is assumed that only one sensor will acquire a bias at any given time.
Once the probability of a hypothesis approaches 1, that hypothesis is declared as the correct hypothesis and the bias associated with the hypothesis is removed from the sensors' reading.
The accuracy and convergence characteristics of the proposed algorithm are verified using experimental results.
This study is essential to ensure accurate operation of vehicle's ultrasonic parking sensors.
