Acceleration is the important data sources of vehicle safety study

and the acquisition of reliable acceleration parameter requires the high precision acceleration sensor.The corresponding acceleration sensor calibration model and model solution algorithm are designed for the basic calibration of three-axis acceleration sensor

aiming at the revising problem of axis not vertical.The precision of acceleration sensor after calibrated and before calibrated are compared through the actual test to verify the availability of calibration method.After the calibration

the multi-axis acceleration sensor error caused by axis not vertical to each other can be reduced to less than 2 %

and this meets the needs of a variety of practical engineering measurement.
