Abstract:In this paper, two different coasting strategies are proposed: one leverages fuel cut-off and another uses engine start/stop. Engine drag torque and energy-cost used for engine restart are considered in the modeling to give a fair evaluation. Then, the performance of these two coasting methods is evaluated with dynamic programming (DP) under various driving scenarios with different slope profiles. Offline simulation shows that the engine start/stop method outperforms the fuel cut-off method in terms of fuel co… Show more
