The invention discloses a slope-based automatic driving speed planning method and device, a medium and equipment, and belongs to the technical field of automatic driving. The method mainly comprises the following steps: calculating a road section gradient of a current road section according to perception information perceived in real time in a driving process of an automatic driving vehicle; if the road section gradient of the current road section is greater than a preset gradient threshold value, calculating a ramp speed correction coefficient of the current road section according to the road section gradient of the current road section and the current driving speed of the autonomous vehicle; and obtaining a current planning strategy according to the ramp speed correction coefficient, and performing speed planning on the autonomous vehicle according to the current planning strategy. On the premise that the average speed of the vehicle is almost the same, the fuel consumption of the vehicle is reduced, and the service life of related parts of the vehicle is prolonged.
本申请公开了一种基于坡度的自动驾驶速度规划方法、装置、介质及设备,属于自动驾驶技术领域。主要包括,根据自动驾驶车辆行驶过程中实时感知到的感知信息,对当前路段的路段坡度进行计算;若当前路段的路段坡度大于预设的坡度阈值,则根据当前路段的路段坡度以及自动驾驶车辆的当前行驶速度,计算得到当前路段的坡道速度修正系数;以及根据坡道速度修正系数得到当前规划策略,进而根据当前规划策略对自动驾驶车辆进行速度规划。本申请能够在使得车辆平均速度相差不多的前提下,降低车辆的油耗,延长车辆相关部件的使用寿命。
