Document Type and Number:
WIPO Patent Application WO/2022/037340
Kind Code:
A1
Abstract:
A fault detection method, apparatus (102), and system (100), relating to the technical field of automatic driving, and being capable of improving the technical problems of high production costs and high system design complexity due to fault detection performed on measurement values of measurement sources using a measurement source multi-backup solution in an existing navigation system (101). The method comprises: obtaining N measurement values corresponding to M measurement sources; performing parallel filtering processing on the N measurement values using a first filter bank, and determining, according to the processing results of the filters comprised in the first filter bank, whether there is a fault measurement value in the N measurement values, wherein the first filter bank comprises a primary filter and N first filters (1, 2, 3, 4, 5); and if yes, determining the fault measurement value in the N measurement values using a second filter bank, wherein the second filter bank comprises (N-1) second filters (11, 12, 13, 14) corresponding to the first filters (1, 2, 3, 4, 5).
