Summary
Previously, we developed an adaptive lane‐keeping controller for vehicles without using lateral velocity measurements. However, the construction of the controller is very complex and not suitable for practical applications. To overcome this problem, we propose an improved adaptive lane‐keeping controller that is much simpler than the conventional controller. To obtain the improved controller, we propose an improved vehicle dynamic expression. In this dynamic expression, fewer elements are estimated adaptively as containing unknown vehicle parameters compared with the conventional expression. Moreover, a control performance improvement method is described theoretically. Finally, we report numerous simulations that validated the effectiveness of the improved controller.
