The embodiments of the present application provide a method and an apparatus for planning a speed of an autonomous vehicle, and a storage medium. The method includes: generating a plurality of speed trajectories to be selected for the autonomous vehicle before the autonomous vehicle changes a lane, wherein the speed trajectory to be selected includes the speeds to be selected at a plurality of time points within a preset time range; obtaining predicted speeds and predicted positions of an obstacle at the plurality of time points; calculating a cost function value of each of the speed trajectories to be selected, according to the plurality of speed trajectories to be selected, the predicted speeds and the predicted positions; and selecting a speed trajectory to be selected with a minimum cost function value as a planning speed trajectory of the autonomous vehicle. According to the technical solutions of the embodiments of the present application, a speed of the autonomous vehicle can be adjusted before the autonomous vehicle changes a lane, so that a distance from the autonomous vehicle to the obstacle on the target lane is increased, thereby creating an opportunity and a safe distance for the lane change, and improving a success rate of the lane change.
