The invention provides a method and device for estimating the slope of a road surface, a vehicle and a computer readable storage medium, and belongs to the technical field of automobile intelligent control. Performing low-pass filtering and band-pass filtering on the speed information and the longitudinal acceleration information; and a slope value theta is calculated. By directly carrying out low-pass filtering and band-pass filtering on speed and longitudinal acceleration information and combining a slope calculation formula, accurate calculation of the slope of the road surface is realized on the basis of using a single-axis acceleration sensor.
本发明提供估算路面坡度的方法、装置、车辆及计算机可读存储介质,属于汽车智能化控制技术领域,包括获取速度信息和纵向加速度信息;对所述速度信息和纵向加速度信息进行低通滤波和带通滤波;计算出坡度值θ。通过直接对速度和纵向加速度信息进行低通滤波和带通滤波,结合坡度计算公式,在使用单轴加速度传感器的基础上,实现对路面坡度的精确计算。
