AutomoTIVA: criação de um shield CAN para a TIVA para coleta de dados veiculares

Abstract

From a purely mechanical system to a large and complex system controlled by computers, the passenger vehicle is one of the greatest representatives of the evolution of technology. This growing vehicular technology, and the data associated with it, added to the evolution of wireless communication technologies, has made the field of vehicular telemetry grow in recent years, with various external equipment being developed and even connectivity within the vehicles themselves. As such, there are many commercial options for end users and fleet managers to connect their vehicles and access data remotely. However, companies that are entering the connectivity business to offer these services have some difficulty using these already available equipment, due to the lack of flexibility and freedom to make changes to the software, for example, to collect some variables of interest. Additionally, the demand for knowledge of automotive embedded systems is increasing, generating the need for new teaching tools that can demonstrate the operation of these systems. With that in mind, the present work sought to develop a board that can be easily connected to the TIVA, with the aim of facilitating CAN communication tests, both to acquire more knowledge about the vehicle, with the acquisition of the desired variables, and to facilitate learning. The result obtained, however, was a prototype to carry out tests only on the bench initially (and therefore with a didactic purpose), however both the hardware and the software can be developed later to be used in real vehicles , fully fulfilling the initial objective.
