A Vehicle Longitudinal Dynamical Model for Propulsion System Tailoring
Rapport, 2020

Integrated vehicle-transportation design, based on specific transportation assignments, has resulted in cost- and energy-efficient transport solutions especially in case of battery electric heavy vehicles. This report presents a longitudinal dynamical vehicle model for fast evaluation of the cost function and constraints within a vehicle-transportation optimization. The model includes conventional, fully electric and hybrid vehicles.
The presented model evaluates energy consumption and battery degradation on driving cycles with varying speed limit and topography. The energy consumption accuracy of the presented model compared to a high fidelity vehicle model has been seen to be about 3% for the tested driving cycles, which can be further improved by tuning parameters.
