DESIGN AND DEVELOPMENT OF EMBEDDED SYSTEM FOR VEHICLE TELEMATICS

Abstract

Telematics is the convergence of telecommunications and information processing. Nowadays the term Telematics mostly refers to automation in automobiles, such as the invention of the emergency warning system for vehicles, GPS navigation, integrated hands-free cell phones, wireless safety communications and automatic driving assistance systems. The main applications of vehicle Telematics are Vehicle Tracking and Fleet management. This project is aimed to design and develop a state-of-art embedded system for vehicle Telematics which shall perform vehicle tracking and provide driver assistance mechanism like adaptive headlight control during night time. The project involves the up gradation of existing hardware design, firmware development, testing and simulation of vehicle Telematics system. The hardware consists of TIVA series ARM Cortex M4 Microcontroller as the main processing unit. The on-board embedded system has a GPS antenna, a GPRS module, a CMOS digital camera and few sensors to monitor vehicle parameters like temperature, fuel, energy, AC, door etc. In this project, a hardware prototype unit is realized. This work involves the development of application software for receiving, framing and transmitting GPS data along with sensor data. The application is developed in „C‟ language. The Telematic prototype unit is tested for its performance. Successful GPS and other sensor data are received at a Laptop that is configured as server. These raw data are decoded and displayed at the receiving station. Algorithm for night time vehicle headlight detection using Artificial Neural Network (ANN) classifier has been simulated in MATLAB and results tabulated. This Telematic design is versatile, reliable and meets the required specifications.
