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 EMBEDDED SYSTEM as 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 withhandle its 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 page 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.
Digital road maps
¢ The new generation microprocessors promises further increase in system capabilities.
¢ The digital road maps, available on CD-ROM™s have substantially increased safety of automobiles.
ADVANTAGES
When traffic slows down vehicle speed is altered using moderate braking to maintain a constant distance between his and other cars.
In advanced systems just in the case the driver over speeds or suddenly falls over and guides the car to a safe halt. And if you have programmed it right, the GPS in the car would take you to your destination .
If a smart thief has managed to break in through the car, the car doesn™t start up even if it does the computer I the car would lock the steering wheel and cutoff the fuel injection supply ¦ in the mean time a signal is set to the nearest police station and the owner informing them about the thief.
Some designs now include so-called "pre-safe" systems, which sense possible collisions in advance based on emergency braking, skidding, and sudden evasive maneuvers.
CONCLUSION
¢ Making the autonomous easy to operate for the user and the designers should concentrate more in producing autonomous cars.
¢ Due to speed control technique, accident free driving is possible and fuel savage is also made possible by the technique.
¢ So that we could find ourselves using these autonomous cars in the near feature.
