The system construction of data acquisition system was introduced , and the working principle , structure characteristic of the LPC2200 and ADIS16355 sensor were expounded. A method for SPI interface of the vehicle motion parameters acquisition system was presented,and the experiment for measuring the vehicle lateral acceleration and yaw rate was performed. Experimental data shows that the data acquisition system is reliable and stable, and the results are satisfied with measurement requirements of vehicle motion.
