The invention relates to a curve speed limiting method and device, computer equipment and a storage medium. The method comprises the steps of obtaining a center line fitting equation according to a lane line detection condition of a current driving road section of a target vehicle; the center line fitting equation comprises a lane center line fitting equation and a track center line fitting equation; the lane center line fitting equation is obtained under the condition that a lane line exists, and the track center line fitting equation is obtained under the condition that the lane line does not exist; determining a preview point on a center line corresponding to the center line fitting equation; the preview distance between the preview point and the target vehicle is determined according to the current driving speed of the target vehicle; obtaining a target curvature corresponding to the position of the preview point according to a center line fitting equation; and according to the target curvature, target braking deceleration is obtained, and the target vehicle is controlled to run according to the target braking deceleration. By adopting the method, the usability of the curve speed limiting function can be improved.
