The invention provides a speed limiting method and device for an automatic driving vehicle, computer equipment and a storage medium, and relates to the field of intelligent driving. The method comprises the steps that the target curvature of the autonomous vehicle at a first position is obtained, the target curvature comprises the first target curvature and the second target curvature, the first target curvature is the corresponding curvature within the foresight distance of the first position, and the second target curvature is the corresponding curvature outside the foresight distance of the first position; and determining a target speed limit value according to the target curvature, and controlling the autonomous vehicle to run according to the target speed limit value. According to the method and the device, the corresponding target curvature can be given no matter in the foresight distance or outside the foresight distance of the automatic driving vehicle, and pre-judgment of the speed limiting curvature inside and outside the foresight distance is realized, so that the automatic driving vehicle can perform speed limiting driving based on the target curvature, speed reduction in advance is realized, the driving effect of the automatic driving vehicle is improved, and the driving efficiency of the automatic driving vehicle is improved. And the comfort and stability requirements of the automatic driving vehicle are ensured.
