The embodiment of the invention provides a curve speed limiting method and device of an intelligent driving vehicle and an intelligent driving controller. The method comprises the following steps: constructing a lane line model according to lane line data collected by a camera; calculating a current curvature and a preview curvature according to a lane line model; performing data processing on the current curvature and the preview curvature to generate a current curve radius; acquiring speed gain data corresponding to the lane environment data according to the lane environment data acquired by the camera; according to a relation table between the curve radius corresponding to the obtained road environment data and the maximum vehicle speed, the maximum vehicle speed corresponding to the current curve radius is obtained; and determining the current curve driving speed according to the speed gain data and the maximum speed of the vehicle. According to the technical scheme, the curve environment is sensed based on the current curvature and the preview curvature of the lane line, intelligent calculation is conducted according to the curve environment and the vehicle driving environment, curve speed limiting is conducted, and driving safety and reliability are improved.
