INTRODUCTION
The car, which is embedded, can simulate the human driver completely and direct the vehicle on the road. .Autonomous vehicle is the drastic change in technical brilliance and developments in different fields with EMBEDDEDSYSTEMas pioneer.Embedded systems are rapidly becoming a catalyst for change in computing data communications, telecommunications, industrial control and entertainment sectors. .
The fine art of automation
•We load the code of our destination in the dashboard computer and turn the car on.
•A fully computerized car capable of doing almost every thing .
•The finger print technologies have been introduced to enter and start your car with the touch of a finger.
Description of Automation of Cars
•Global Positioning System (G.P.S) using satellites can provide positioning information and proves to be a versatile all-time.
•The models for GPS also include aiding sensors, e.g. dead reckoning, radar and camera.
•An accurate steering control is obtained using Pulse Code Modulation technique
Interaction with Environment
•The vehicle is required to withhandleits environmental capabilities with its intelligent controls.
•basic driving functions consists of lane-keeping, safe distance maintenance, timely lane changing and overtaking.
WADGPS concept
•The Master Control Station (MCS) receives the positioning information from the satellite by employing this concept.
•The MCS is linked to GPS instrumented position location systems (PLS) installed on the autonomous vehicles through a data link sub system (DLS). The DLS can either use VHF or UHF or L-band, incorporating time division multiple access protocol to handle on the roads.
Dead reckoning performance
•Once the vehicle commences the journey the sensors continuously keep track of the direction and displacement of the vehicle .
•The desired destination and starting position of the vehicle together with the time of travel.
