Implementación de un sistema electrónico de control de velocidad para automóviles a inyección basado en el posicionamiento global.

Abstract

An electronic speed control system was implemented for automobile with injection in the positioning that consists of two important parts as :satellite communication and control of the vehicle injection system .Satellite communication is based on obtaining data in NMEA(National Marine Electronics Association ) navigation protocol in a vectorized way in order to have a plot with the length, latitude and speed .The plot is un-vectorized ,with the Coticchia-Surace method ,converted to plane coordinates and with analytical geometry ,the translation of the axes is obtained for each case. The Arcgis software permits to create study buffers at Ambato canton to draw the limits, which limits the speeds established in the Traffic Law by zone , 50 km / h for urban ,70km /h for rural or perimeter and 90km / h on the road .In the control of the injection system ,the signals of the sockets that feed the injectors are handled ,with the operation tests of the electronic system ,the programming strategy is elaborated to condition the information that is executed in real time and worked with interruption by time which reduce and control the speed. The system was tested on a Chevrolet car that responded appropriately to the speed changes produced by the zone change registered by the global positioning .It is concluded that the implemented system works in a stable way ,guaranteeing the change and automatic aped control according to the zone ,keeping its components at normal temperature ,with a current consumption of 0.48% of the total useful life of the battery car .Periodic maintenance of the injectors is recommended to comply with the requirements established by the system.
