Gradeability for Automobiles

Abstract

The demand for transport has been growing rapidly and the footprints of roads have been widespread to areas which were previously inaccessible, especially hilly areas. Road inclinations are not always at zero. Vehicles should have the capability to take gradients even on full loads. The Gradeability of a vehicle is dependent on multiple factors such as the type of road surface, weight of the vehicle, tractive effort at the wheels, tire grip (at low speeds the aerodynamic drag is ignored). Since a vehicle should be ready to be driven on all types of terrains, tractive effort and tire grip become the deciding factors. This paper presents a method to determine the gradeability and enhance it to the required scale.
