摘要:
为了提高路面坡度角的识别精度,该文提出1种基于多信息融合的识别算法。分析纵向加速度对车身姿态的影响,并在Simulink中建立路面坡度识别模型。通过仿真分析得到车身纵向倾角与加速度的关系。利用拟合得到的修正系数对倾角传感器信号进行修正,然后与用坡度测量仪测得的真实角度进行对比分析。实车实验表明,该算法具有较强的抗干扰能力,能够准确识别当前路面坡度角,且波动范围小于±1.5°。
Abstract:
To improve the recognition accuracy of road slope angles,a recognition algorithm based on multi-information fusion is proposed here.The effect of longitudinal acceleration on vehicle body posture is analyzed,and a road slope recognition model is built by Simulink.The relationship between the longitudinal inclination angle and the acceleration is obtained through simulation.The tilt sensor signal is corrected using fitting coefficient and compared with the real angle measured by a slope measuring instrument.Experimental results show that the algorithm has strong anti-interference ability,and can identify current road slope angles accurately,and the fluctuation range is less than ±1.5°.
