摘　　要：针对目前用电机驱动齿轮感应传感器产生再现轮速信号存在成本高、重复性差、真实性差和精度低等问题,设计一套基于LabVIEW的实车ABS四轮轮速传感器信号再现系统。该系统采用铁芯和线圈组成的非机械静态激励方法代替传统系统中的电机和齿轮。试验研究表明,实现对轮速传感器在高低温环境下,高速和低速下进行连续高精度测试,并且得到与实车匹配的真实可靠轮速信号,降低了测试成本,测试的可重复性强,满足现代化汽车轮速传感器生产要求。In order to the problems of high cost,poor repeatability,poor authenticity and low accuracy in generating repro⁃duced wheel speed signals with motor⁃driven gear induction sensors,a set of real⁃vehicle ABS four⁃wheel speed sensor signal re⁃production system based on LabVIEW was designed.The system used a non⁃mechanical static excitation method composed of iron core and coils to replace the motors and gears in the traditional system.Experimental tests show that continuous high⁃precision tes⁃ting of the wheel speed sensor in high and low temperature environments,high speed and low speed,is achieved,and a true and reliable wheel speed signal matching the actual vehicle is obtained,which reduces the test cost and has strong test repeatability,meeting the production requirements of modern automobile wheel speed sensors.
