Non-linear trajectory generation and lateral control new algorithms to minimize platoon's oscillations

Abstract

The lateral and longitudinal oscillations in a platoon of vehicles depend, fundamentally, on how the reference trajectory of the followers is generated and how the lateral and longitudinal control is designed. In this paper new algorithms are presented to reduce some of these problems. One of them takes charge in generating the reference trajectory of the followers by means of a series of points, where the separation between them is based on the kinematics of the vehicle, the trajectory curvature, and on the permissible error. The other one, the lateral control algorithm, takes charge of following the desired trajectory (the generated one). This algorithm is based on the look-ahead distance strategy. In addition, this paper presents simulation results for these algorithms and the comparison of the proposed lateral control with other published one.
