Plataforma de carro elétrico em escala reduzida para estudo e desenvolvimento de controles eletrônicos

Abstract

This Project aims to develop a study platform and improvement of electronic controls for electric vehicles, using a system on a reduced scale controlled by a radio control. In line with the concepts of electric car and autonomous system, it is also proposed a technological innovation: to use a system composed by 4 electric motors which will generate independent traction in each one of the 4 wheels. With the aim of realizing an efficient and low cost study – so it can instigate posterior studies and development – in the first moment a theoretical background was sought, to make possible understanding the actual needs; also, a study about the automobile and auto models systems was realized; posteriorly, the project itself was developed, searching for the best way to apply the technical knowledge acquired in the auto model, accessibly; finished it, it was possible to make the prototype, along with some simulations for the embedded system and the realization of the mechanic structure, adapted to receive the 4 motors; Lastly, an electronic control was developed: the traction control system. In this proposal, it was challenging to work by breaking a huge automotive paradigm: the one which says that one car must have only one motor. That because, in the Market, there are no parts pattern to make up a differentiated system, and most of the components had to be adapted. However, despite the complexity of the auto model’s mechanic part, it was concluded that it was simpler and more efficient to develop electronic systems when there is independent traction in the four wheels.
