摘　　要：针对目前汽车轮速传感器测试系统效率低等问题,设计了一种基于LabVIEW的汽车轮速传感器的功能测试系统。该测试系统综合运用虚拟仪器技术、数据采集技术以及计算机自动化处理技术,对汽车轮速传感器的输出信号进行采集和处理。通过实际运行测试,证明所设计系统稳定性高、实时性强,测试精度达到0.1%,测试速度达到10.5 s/pcs。软件界面友好,能快速检测轮速传感器各项指标是否合格,有效提高了轮速传感器的检测效率和准确性,确保了产品的出厂合格率在100%的水平。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.
