Development of the Autonomous Vehicle Trajectory on the Hilly Road Using Approaches of Eco-Operating Modes
Publication: Resilience and Sustainable Transportation Systems
ABSTRACT
This paper presented the development of a novel approach to generate the trajectory for an autonomous vehicle running on a hilly road using approaches of eco-operating modes to minimize the fuel consumption. The study analyzed the ecological approaches for the accelerating mode and the braking mode. First, the curvilinear function of the eco-accelerating mode was developed by analyzing the profiles optimized by the genetic algorithm. Then, the curvilinear function of the eco-braking mode was generated and proved to be effective by the mathematical method. In this development, the fuel consumption model based on the vehicle specific power (VSP) was implemented with road conditions obtained from digital road maps. Subsequently, the development scheme of the vehicle trajectory on the hilly road was proposed by using the eco-accelerating mode, the eco-braking mode, and the cruising mode. It was shown that compared with the fix speed drive (FSD) vehicle, the fuel savings of the ecological speed drive (ESD) vehicle were 1.8%, 3.9%, 4.5%, and 3.4% when running on an up slope, a down slope, an up-down slope, and a down-up slope, respectively. Finally, when the proposed approach was adopted on a simulation network, its ability to reduce the fuel consumption was analyzed under different traffic volumes and market penetration rates of ESD vehicles.
