Diseño y construcción e implementación de un sistema de reconocimiento de objetos de carretera durante la conducción, bajo condiciones adversas, en el vehículo

Abstract

It has been designed, built and implemented a system of recognition of roadside objects while driving under adverse conditions in a vehicle based on the driving ADAS systems. The objective of the system is to provide greater safety when driving a vehicle under adverse conditions such as rain, fog, or low visibility. The system uses an electronic control module that receiving signals from a long range laser sensor located in the front of the vehicle. This module processes the information received to show through an LCD screen located in a visible place for the driver, the distance to an object located in the vehicle`s path are also controls power to audible and visible indicators agreement certain parameters set out in the schedule to inform the driver of several ways the presence of an object. The elements of the system are: Activity Board Propeller as control module, laser rangefinder SF02, Serial LCD, LED, voltage reducer, resistors and switches. Two modes of operation were established, one called urban and another called road, whose performance difference functions in the distance ranges for activating detection indicators. Test performed by the system in three types of environmental conditions: Free External Factors, under normal conditions and under adverse conditions. The results of the test led to the conclusion that there is an error of 30 cm, achieving successfully implement the system in the vehicle being a reliable assistant driving under all environmental conditions where the driver requires active. This system can produce on a large scale in the country contributing technological innovation and improving driver safety.
