The improved pure pursuit algorithm for autonomous driving advanced system

The pure pursuit algorithm is one of the hottest research fields of autonomous driving advanced system as well as a major means for realizing intelligent operating of autonomous driving advanced system in future. This paper presents a thorough research on GPS automatic navigation technology of autonomous driving advanced system considering that working conditions and field conditions for the vehicle are complex and that there is a high requirement on the precision of the driving path of the vehicle. The advanced pure pursuit algorithm with 2-degree polynomial function in the vehicle velocity and the shortest distance between the GPS trajectory and current vehicle position was studied and analyzed. The proposed algorithm could calibrate the heading and steering angle of the vehicle and reduce lateral error when the vehicle tracking ideal path. Experimental results show that the algorithm is more accurate than the traditional algorithm by improving 54.54%.
