Design of automobile motion parameters stored testing and measuring system

A design scheme is given for the automobile motion parameters stored testing and measuring system. The system include velocity and acceleration signal processing circuits, the low pass filter of acceleration signal, the sampling and storing circuits, the data reading circuit and so on. The accelerators ICS3002-002 and ICS3255-100 are used to measure the automobile acceleration after the analysis of automobile motion parameters characters. The velocity signal processing circuit is universal for different types of automobile velocity sensors. The methods of data sampling and storing are put forward. The optimization for the system is given as well.
