Abstract
The purpose of this work is to develop a strategy of energy management of a hybrid articulated heavy truck by using longitudinal vehicle dynamic modeling. This study is focused on the torque management offered by the engine of an articulated heavy truck that is based on the use of a four-stroke internal combustion engine (ICE) of the tractor and one electric motor coupled directly to the axle of its trailer. The articulated vehicle has an independent drive axle to assist in maintaining its speed, both on hills and downhills. Equations of motion for these dynamic systems are solved in the MATLAB® environment, where a road profile is introduced as an input mode observing the 3% maximum slope National Department of Transport Infrastructure (DNIT) restriction for roads with a limit of 80 km/h. The results have shown that this type of strategy can be an important tool for fossil fuel savings as well as mitigating polluting gas emissions.
