Abstract: According to the complex clamping mechanism and the large measuring error of the vehicle steering wheel parameter measuring instrument, a steering parameters measuring instrument method based on multi-sensor data fusion is proposed. The method compensates the angular velocity of the gyroscope through acceleration sensor and geomagnetometer, and the data sampled by the 9-axis MEMS sensor are fused by quaternion fusion algorithm, so as to correct the influence of wheel tilt angle on measurement results. The hardware platform of steering parameter measuring instrument is designed to verify the feasibility of the algorithm, the experimental results show that the proposed algorithm can improve the accuracy of angle measurement significantly.
