Virtual Correlation in Fuel Consumption Analysis 2015-36-0217

Fuel efficiency is an essential matter at commercial vehicle development. High fuel consumption of commercial vehicles has been considered synonymous with inefficiency or absence of available resources and budget to test more driveline configurations in different customer missions. The Brazilian market has a several request of mission profile, trailer configuration, load distribution, average speed, productivity and fuel economy target. Due to the increase of operational cost, customer expectation of profitability and market competition the company need create some different methodology to develop the best line up for each customer without impact on the program milestones and budget.
The aim of this work is developing of methodology of analysis and correlation of data acquisition system used for measuring the speed and position of a moving vehicle (VBOX GPS) with the vehicle control module (VCM) available data in controller area network (CAN) to create a virtual vehicle model with the real driver interface and target of productivity. The virtual vehicle model is processed in software of dynamic analysis based on MATLAB / Simulink with possibility to tuning all driveline input and driver interfaces to evaluate the best commitment of line up for each customer mission.
