The invention discloses a curve control method and device of an adaptive cruise control system, equipment and a medium, and relates to the technical field of automatic driving, and the method comprises the steps: obtaining a current curvature value and a current curvature change rate of a vehicle at a current lane position; determining a current curvature gain based on the current curvature change rate, and optimizing the current curvature gain based on a relationship between the current curvature change rate and the current curvature value to obtain an optimized curvature gain; determining a current lane curvature based on the current curvature value, the current curvature change rate, the optimized curvature gain and a longitudinal distance between a preset aiming point position and the vehicle; and determining a target vehicle speed by using the current lane curvature and the current transverse acceleration of the vehicle so as to control the vehicle to run in a curve by using the target vehicle speed. The comfort, the stability and the timeliness of the adaptive cruise control system in curve control are improved.
