Projeto e desenvolvimento de um sistema de controle para permitir a dirigibilidade de um veículo por meio do acionamento de um joystick.

Abstract

This work aims the development of a control system, to allow the handling of a automotive vehicle, by moving a joystick, which replaces the steering wheel, accelerator and braking pedals and is operated by a user. An electronic control board was built to receive control signals, such as steering, acceleration and braking signals, using a joystick handled by a user. It converts those signals and activates the mechanical actuators in the steering wheel, brake booster and accelerator, to allow the dynamic control of the vehicle. To test that control system, it was developed a vehicle dynamics simulator, which provides, in real time, the dynamics responses of a vehicle when driven by a user, by steering, braking and accelerating commands. Together with the simulator it was developed a test bench, with mechanical actuators, sensors, a control board and a joystick, which were tested in real time, by a user driving a vehicle with the assistance of the simulator, on a virtual road, performing maneuvers like curves, accelerations and varied braking.
