Desenvolvimento de sistema de troca de marchas via borboleta para carros fórmula SAE

Abstract

Cars that attend Formula SAE competition are recognized by the agility in curves and high acceleration from stand position, being such characteristics developed along an extensive work among many areas that comprises the vehicle. One of them, even though not outstanding, contributes significantly for a better performance, being the gear shifting system. This work has the goal of developing a simplified gear shifting system, aiming improvements related to pilot ergonomics and performance of the teams that adopt the structure established along the content, always having in mind the lowest cost possible and implementation/replication system easiness. To achieve this goal, the research happened through the development of a code responsible for gear changing process (paddle shift) and functional tests at hardware and firmware simulation platform called Proteus, comprising metal oxyde field effect transistors, solid state relays and microcontrolled platform (Arduino). As a result, the system presented expected operation in all simulations made.
