The Research on Test-Bed Test System of Automobile Eddy Current Retarder

Test-bed test system of automobile eddy current retarder is studied. After introduction to sensors needed and detection principles, the process of signal collection and treatment by singlechip is put forward. Besides, precision compensation and standardization of sensor is conducted, all constituent parts and function are introduced, including forward computer interface. Simple analysis and discussion is conducted on analogue principle of two operation stations of retarder. In the end, the design idea of test software is put forward and flow chart of the design is provided.
