• This paper presents a design approach for tuning autonomous driving controllers of road vehicles. In this regard, a bicycle vehicle model and a model predictive control (MPC) algorithm have been applied to the tracking-control lateral of autonomous vehicles. Additionally, in order to maximize ride comfort and minimize path-following error, a multi-objective optimization problem has been formulated. In the multi- objective optimization problem, a meta-heuristic search algorithm, i.e., non-dominated sorting differential evolution (NSDE), is applied, the design objective is to improve ride quality and reduce tracking-control errors, and the design variables are weighting factors of the MPC controller. Numerical simulation is performed to demonstrate the effectiveness of the proposed design approach.
