摘　　要：为了完成汽车轮速传感器和齿轮的高效率、高精度、高可靠性能测试,在汽车轮速传感器检定算法上,研究了目前普遍流行的占空比误差参数测试算法及其存在的缺陷,分析了影响占空比误差精度和可靠性的各种因素,提出了一种全新的基于上升沿和下降沿最大周期、最小周期的Pitch error(齿轮的)周节误差算法,较好地反映了信号的失真大小,优化软件算法;设计的基于LabVIEW最大周期、最小周期误差参数测量模块,并已成功应用于汽车轮速传感器检定测控系统中。In order to complete the test in high efficiency, high--precision and high reliability for auto wheel speed sensor and gear, the testing algorithm of the current general popular parameters of duty cycle error and its defects are studied. The factors affecting the accuracy and reliability of duty cycle error are analyzed. A new Pitch error algorithm of the maximum cycle and the minimum based on rising edge and falling edge is provided, and it reflects the signal distortion better and optimizes software algorithms. Module of parameter of the maximum and minimum cycle Pitch error measurement is designed based on LabVIEW, and has been successfully used in the auto wheel speed sensor test system.
