In order to provide reliable and stable data for automotive active safety system
an acceleration data acquisition system for automobile is designed which consists of ARM7 microprocessors and MEMS sensors.Hardware structure and software design of the system are described.In the experiments
acceleration data of static state is collected and analyzed and acceleration data of traveling state is filtered.By analyzing
the groups of data have similar statistical properties
measurement noise of acquisition system is Gaussian white noise and measurement data is reliable.
