VARIABLE POWER VEHICLE DYNAMICS MODEL FOR ESTIMATING TRUCK ACCELERATIONS

This paper introduces the concept of a linearly increasing variable power to the basic vehicle dynamics model that has been proposed in the literature. The paper also calibrates the model to typical truck classifications 8–10 that travel along interstate highways in the United States. The proposed enhancement is demonstrated to result in significant improvements in vehicle performance curves, especially at low speeds when vehicles are engaged in gearshifts.
