Control del funcionamiento de sensores actuadores y verificación de la ECU mediante la implementación de un motor virtual para la Escuela de Ingeniería Automotriz.

Abstract

The main objective of this work is to build an electronic computer to analyze the operation of sensors, actuators and verification module engine control (ECU) at different pressure ranges without the vehicle is in motion, for it was made a study of the electronic injection systems that the cars have. The electronic equipment contains several elements and a PIC 18F4550 microcontroller incorporated into different circuits with their respective programs, its memory extensive to store all the information that is used to simulate the operation of sensors and actuators , and to generate voltages required in the analysis , it is commanded by pushbuttons and their values are displayed on a LCD screen. The computer is a tool of automotive diagnostic and promotes a better understanding of student learning to encourage them to use and develop technological innovation, since this virtual engine is not sold in the domestic market, opening up possibilities for generating and technological improvement in this type of product. A user manual was developed for the student to know the functioning of the equipment before use it and also we implemented a laboratory guides allowing different practices to check the status of each vehicle components. With the equipment we obtained positive results as the simulation of the sensor signals, generates pulses for actuators and to make a diagnosis of each of the sensors and actuators of the vehicle.
