In view of the problems of low accuracy, poor repeatability and large testing limitations in traditional motor-driven mechanical gear testing methods for smart wheel speed sensors, a smart wheel speed sensor test system based on LabVIEW is designed. The system adopts the static electromagnetic excitation sensor test method of non-mechanical components and innovatively designs a rotating magnetic field generator module, which can simulate the rotation speed and direction of any gear rotation, and realize the test of the wheel speed sensor at extremely low and extremely high speeds. Experimental research shows that the designed test system can test the functional parameters such as the high, medium and low current value, frequency and duty cycle of the output signal of the smart wheel speed sensor and analyze the sensor protocol information. The output frequency range of the tested sensor can reach 1~3 KHz, which improves the accuracy of the test system. The hardware platform of the system is built by modularization and has strong generalizability; the software adopts LabVIEW, simple graphical operation and display interface, which is convenient for testers to monitor and analyze the sensor output characteristics and adapt to the production requirements of modern wheel speed sensors.
