The invention relates to a variable-speed dynamic lane changing track planning method based on a vehicle driving rule. The driving safety and comfort of the vehicle are controlled through the acceleration and the jerk; and a speed change rule is fused into a trajectory planning method, a cycloid * and a circular curve * are adopted as motion primitive planning lane change trajectories, so that thelane change trajectory of the automatic driving vehicle is consistent with an automatic cruise trajectory, and the lane change trajectory is dynamically updated in real time in combination with the latest position and the safety distance of the vehicle until the automatic driving vehicle completes lane change. A speed change rule is originally introduced into lane change motion, and the vehicle lane change efficiency is improved; the acceleration and jerk required by comfort and safety are considered while the trajectory is generated, the process of searching for the optimal trajectory by setting an optimization target in the past is omitted, the optimal trajectory is directly calculated under constraint, and the efficiency is remarkably improved. After a certain time interval, dynamic iteration is carried out to recalculate the planning trajectory, thereby ensuring that the end point of the vehicle planning trajectory is beyond the safe distance in real time, and effectively correcting the error of path tracking.
