Complex dynamics in a vehicle platoon with nonlinear drag and ACC controllers
For researchers in vehicle platooning, this work highlights the impact of nonlinear drag on ACC design, but the results are incremental and lack quantitative benchmarks.
This paper models a vehicle platoon with nonlinear aerodynamic drag and ACC controllers, using bifurcation analysis to show that proper ACC configuration is critical for platoon convergence.
In this paper a novel platoon model is presented. Nonlinear aerodynamic effects, such as the wake generated by the preceding vehicle, are considered, and their influence in the set up of a Adaptive Cruise Controller (ACC) is investigated. To this aim, bifurcation analysis tools are exploited in combination with an embedding technique independent from the vehicles number. The results highlight the importance of a proper configuration for the ACC in order to guarantee the platoon convergence to the desired motion.
