Desarrollo e implementación de un sistema de control electrónico mediante comandos de voz para mejorar la seguridad, confort e interactividad de un vehículo convencional.

Abstract

The purpose of this project is to develop and implement an electronic voice control system, by using free software and hardware to improve the safety, comfort and interactivity of a conventional vehicle. This is mainly due to the need to reduce motor vehicle accidents induced by distracting activities while driving, as well as the high cost of a system capable of controlling the electronic actuators by voice. For which, it began with the review of the state of the art and the development of the source code. Next, through an experimental design, the voice recognition system was simulated; using a free hardware microcontroller, a voice recognition module, a relay module and by means of a protoboard, a series of LEDs were connected with their respective resistors; these LEDs simulated the electronic actuators of the vehicle when changing from a High/Low state when pronouncing a preset command. Later, this system was implemented in a conventional vehicle and launched thanks to a Raspberry Pi computer board, which in turn led to the system having various levels of security and the possibility of loading a free operating system focused on ethical hacking. In addition, a parking assistant activated by the same voice recognition system was installed, which has a series of ultrasonic sensors and an acoustic signal that is activated when the vehicle encounters an obstacle less than a meter away.
