Determinar rutas urbanas para el desarrollo de ciclos de conducción representativos de la ciudad de Ambato para evaluar el consumo energético en vehículos

Abstract

The Ecuadorian territory is made up of different geographical areas, with differences in altitude that affect the performance of vehicles, the constant population development of Ecuador’s cities has triggered the arrival of new car brands in the country; these do not provide users with clear information on the energy consumption of the units within the Ecuadorian territory. Ambato is a city that does not have representative driving cycles of its geography, which makes it impossible to obtain an analysis of the real operating parameters of vehicles that reflect the way and regularity of driving. Therefore, the objective of this technical project was to evaluate urban routes by collecting driving factors through an OBDII device to obtain characteristic cycles of the city. The methodology implemented was by means of a testing protocol which consisted of route selection, vehicle selection, instrumentation, parameter selection, data collection, data analysis by means of the longitudinal vehicle dynamics model and the statistical method of maximum and minimum weighted differences to obtain the characteristic cycle. Through this methodology, it was possible to obtain the representative cycle of the selected routes, choosing the trip with the minimum differences with respect to the average of all the analyzed parameters of the 30 trips made per route. In this context it is concluded that the energy that most influences the driving cycle is the slope resistance due to the differences in altitudes that exist in the city.
