Abstract

Introduction: The fuel consumption of the ground vehicle transportations constitutes an important part in the total fuel consumption of the world. There are many factors related to this fuel consumption and several ways to study it. The drive cycles based on the mathematical modeling are tools to understand, to estimate and to predict the vehicle fuel consumption.

Objective: Usually the simulating is most exact when the mathematical models are solved with the real profiles of way resistance coefficient. For that reason, the experimental determination of the coefficient of resistance of the road is the objective of this research.

Methodology:  A trailer was designed and built and statically and, in order to know the features of the systems that are involved in the coefficient measuring process, a group of experiments of static and dynamic was conducted. Later, a road sector for validation was calibrated and then others road with variation in slope and road surface was studied.

Results: This method is able to measure the way resistance coefficient that corresponding with road conditions of values of rolling resistance of 0,008 - 0,02 (made of asphalt or cement) and slopes of 0-12o.

Conclusions: The results demonstrate that this method is accurate and precise for the determination of the way resistance coefficient.
