Modelagem longitudinal, controle e redução do consumo energético de um veículo elétrico

Abstract

The increase in competitiveness, sustainability and the reduction of the development cycle forced the auto industry, together with the research centers, to invest in simulation for new products. With this tool developed, an early intervention can be made even in the design phase, without having to conceive the prototype. The proposed simulation methods are implemented based on vehicle dynamics, which generally deals with the relationship between the vehicle, the environment where it is traveling and the commands imposed by the driver. The information extracted from the simulation was loaded in the developed algorithm, which returned numerical information and graphs in the used software. The results presented in the computational model showed the dependence of the vehicle parameters (mass and gear ratio) and the driver’s commands, with energy efficiency. As for the motor design, the balance between the motor and the gear ratio of the prototype was taken into consideration, respecting the nominal power, torque and rated speed of the motor. Finally, the computational model resulting from this work was used to increase the energy efficiency of an electric vehicle, where the acquired results verified the feasibility and validity of the approach.
