This strategy was demonstrated in simulation and implemented on a Navigation Test Vehicle. For a test path of varying curvature, the average lateral.

A great paper on adaptive pure pursuit can be found here. How it works . Pure pursuit works by finding a lookahead on the path. It does this by finding the intersection of a circle of a given radius with the path. Then, the robot seeks the lookahead by calculating curvature and velocity to reach the lookahead. Implementing Pure Pursuit.

In order to evaluate the performance of the proposed controller, a non-adaptive controller is compared with the adaptive controller via computer.

Published 2017. Computer Science. Pure-Pursuit (P-P) model is widely used in the path tracking for unmanned vehicles because of its simple, practical, efficient and intuitive. But it has poor adaptability to the change of vehicle speed. Because the controller parameter (forward-looking distance) is constant, the ordinary P-P model can only.
