Data-Driven Robust Optimization for Energy-Aware and Safe Navigation of Electric Vehicles
share
In this paper, we simultaneously tackle the problem of energy optimal and safe navigation of electric vehicles in a data-driven robust optimization framework. We consider a dynamic model of the electric vehicle which includes both longitudinal and lateral motion as well as dynamics of stored energy level. We leverage past data of obstacle motion to construct a future occupancy set with probabilistic guarantees, and formulate robust collision avoidance constraints with respect to such an occupancy set using convex programming duality. Consequently, we present the finite horizon optimal control problem subject to robust collision avoidance constraints while penalizing resulting energy consumption. Finally, we show the effectiveness of the proposed techniques in reducing energy consumption and ensuring safe navigation via extensive simulations.
