The invention provides an automatic driving speed control method and device, and relates to the technical field of automobiles. The method comprises the following steps: acquiring road type information of a vehicle; acquiring the current driving speed and the current driving time of the vehicle; and determining the driving acceleration of the vehicle according to the road type information, the current driving speed and the current driving time. Compared with an automatic driving method in the prior art, the technical scheme has the advantages that automatic driving longitudinal control (vehicle speed control) is combined with high-precision map information; and the influence caused by the slope of the road surface is considered in the automatic driving speed control process, so that the automatic driving precision is improved.

    本申请提供了一种自动驾驶车速控制方法和装置,涉及汽车技术领域。所述方法包括:获取车辆的道路类型信息;获取车辆的当前行驶速度和当前行驶时间;根据所述道路类型信息、所述当前行驶速度和所述当前行驶时间,确定所述车辆的行驶加速度。本申请的技术方案与现有技术的自动驾驶方法相比,不仅将自动驾驶纵向控制(车速控制)与高精地图信息相结合;还在自动驾驶车速控制过程中考虑路面坡度带来的影响,提高了自动驾驶的精度。
