Title:
METHOD AND DEVICE FOR TESTING POSITIONING AND SPEED MEASURING SYSTEM MAIN UNIT
Document Type and Number:
WIPO Patent Application WO/2022/148360
Kind Code:
A1
Abstract:
A method and device for testing a positioning and speed measuring system main unit. The method comprises: obtaining a first simulated signal, the first simulated signal being obtained by simulating absolute position sensors and relative position sensors (S101); sending the first simulated signal to a positioning and speed measuring system main unit to be tested (S102); obtaining a first result calculated by said positioning and speed measuring system main unit according to the first simulated signal (S103); obtaining a second result calculated according to the first simulated signal, the second result being a reference result corresponding to the first simulated signal (S104); and if the result of comparison between the first result and the second result exceeds a preset range, determining that said positioning and speed measuring system main unit is abnormal (S105). A positioning and speed measuring system main unit can still be tested without components including absolute position sensors and relative position sensors, the test process is simple and easy to implement, a test environment can be built without large-scale investment, and the cost is saved.
