In this paper, a novel model based online ECMS controller is implemented on a dynamic forward-facing simulation model of a fuel cell powered heavy-duty truck. In addition, to accurately account for driveline dynamics, suitable rate limiters are implemented in the surrogate model. The proposed modelling approach eliminates the need of a-priori ECMS calculations, and thus offers a significant workflow improvement. The resulting control strategy is applied and evaluated on two different regulatory cycles.
