Design and Research of Portable Motor Vehicle Brake Performance Tester

Made a comparative analysis of the research situation and development trend of braking performance testing technology at home and abroad at present.On the basis of researching current braking performance tester characteristics,functions and technology development,we puts forward a design scheme of portable motor vehicle braking performance test system which is based on the SCM C8051F340,of C8051F series.On the basis of the consideration of the performance and cost,for the core to the SCM C8051F340 and the special triaxial digital acceleration sensor LIS3LV02DQ,designed a basic platform with the cost-effective performance of portable braking performance tester.Through the data of the static calibration in the laboratory and real car test on the road,verified the measuring precision,repeatability and stability of the instrument.
