Aiming at problems of low efficiency of the existing auto wheel speed sensor test system

a function test system of auto wheel speed sensor based on LabVIEW is designed. Virtual instrument（ VI） technology

data acquisition technology

and computer automation processing technology are used to acquire and process output signal of the sensor. Through practical operation test

it shows that its stability and real-time performance is very good

testing precision reaches 0. 1 %

and testing speed reaches 10. 5 s / pcs. Software interface is user-friendly

and can rapidly detect whether each index of wheel speed sensor is qualified

and effectively increases testing efficiency and accuracy of sensors and guarantee 100 % of pass.
