Study of the Algorithm of Auto Wheel Speed Sensor Testing Based on LabVIEW

摘要：

Auto wheel speed sensor and target gear are the information sources and key components for auto electronic control system,and it is also one of the core technology in the research field of automotive electronics,it becomes the challenge for auto test sector to test the auto wheel speed sensor in high efficiency and high-precision. In order to complete the test 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 affect 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.
