![]() Este proyecto implementa un sistema basado en el protocolo OBD-II sobre un bus CAN, que permite visualizar variables en tiempo real y realizar un diagnóstico del estado del automóvil que muestra los códigos de funcionamiento, falla y rendimiento energético. The scanner has a USB connection that eases the graphical visualization of data in a PC through an interface created in LabVIEW.ĭesde su surgimiento, el objetivo fundamental del estándar OBD ha sido el control de los gases emitidos por los automóviles y de sus efectos en el medio ambiente. We implemented an OBD-II system located at the end of the test vehicle (a bus) –which corresponds to the scanner or diagnosis unit– in an Arduino Mega 2560 development board connected to a CAN transceiver-controlled composed module. The on board diagnosis systems allow to retrieve the stored failure codes together with a large number of variables –important for the diagnosis– such as speed, fuel level, and CO2 emissions in real-time. This project implements a system based on the OBD-II protocol over a CAN bus, which allows the visualization of variables in real-time and the performing of a diagnosis of the vehicle state showing the operating, failure, and energy consumption codes. From its origin, the main objective of the OBD standard has been the control of the gases emitted by the vehicles and its corresponding effects in the environment. ![]()
