Towards an Analytical Eco-Driving Cycle Computation for Conventional Cars

摘要

This paper proposes an analytical methodology to obtain a fuel optimal vehicle speed trajectory in order to realize a trip with a conventional vehicle with an internal combustion engine (ICE). In order to give an analytical formulation of the issue, Pontryagin’s Maximum Principle (PMP) was used. The expression considers the driving constraints (e.g. consumption, distance, duration) with respect to control variables (e.g. time, position, vehicle speed, engine torque). The knowledge of an optimality is needed to find the optimal solution. The reference solution used to compare results was Dynamic Programming (DP). The analytical methodology developed in this paper led to a +1.1% error in consumption compared to DP simulations for the same trip with the same constraints of rendez-vous.
