| 摘 要： | 针对目前场(厂)内机动车方向盘转向参数测量仪装夹机构复杂、测量结果误差大的问题,提出一种基于多传感器技术的转向参数测量仪方法。通过加速度传感器、地磁计对陀螺仪角速度进行补偿,采用四元数融合算法对9轴MEMS传感器采样数据进行融合,修正因方向盘倾角对转向角测量结果的影响。通过设计转向参数测量仪硬件平台验证算法的可行性,实验结果表明融合算法能够提高转向角的精度。

| 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. |
