Over speed indication and Automatic accident Avoiding System for four wheeler


The Object of this project is to detect the speed of the vehicle and cutoff the fuel if it exceeds set speed. This project is designed with micro controller, Proximity Sensor asspeed sensor and driver circuit with Relay and keypad.
In this project we are using Proximity sensor as a speed detector.  A Proximity sensor can detect objects without physical contact. A proximity sensor often emits an electromagnetic field or beam and look for changes in the field. The object being sensed is often referred to as the proximity sensor's target. Here is an inductive proximity sensor, requires a metal target.
  The proximity sensor fixed near the wheel of vehicle to detect the sensor we fixed one plate on the wheel. When vehicle is traveling on the road proximity sensor crosses the plates and it gives the signal to micro controller.

Except for the Autobahn in Germany, almost all roads have specific speed limits. And it is difficult for the driver to always look out for speed limits signs and adjust his speed accordingly. Over speed indicator is a device that tells the driver if he is exceeding the particular speed limit. With the over speed indicator in your car you can be sure that you are not going get yourself booked for over speeding. The system has a computer which stores the speed limits of different areas. The GPS in the system feeds the exact location of the car to the computer which looks up in its database to determine the permissible speed for the area and limits the car within the allowable speed.
Accident Avoidance systems in a four wheeler is a cocktail of several technological marvels.
1. Emergency Brake Assist (EBA)
In an emergency, many people do not depress the brake pedal hard enough. EBA senses an emergency braking situation and helps the driver to reduce speed in the shortest distance possible.

2.  Dynamic Stability and traction Control (DSTC)
DSTC makes driving on twisty and slippery road conditions safer, by using sensors to detect whether any of the wheels is losing traction. DSTC has the ability to cut power in a flash, helping the car to regain its grip. If in any case the car shows a tendency to skid the system automatically slows the particular wheels to help maintain control.

3. Electronic Brake Distribution (EBD)
EBD makes sure that the braking forces of the car are distributed between the front and the rear brakes in order to optimize braking efficiency.

4.  Anti-Lock braking system (ABS)
With ABS you can brake as hard as you can and steer yourself to safety without the fear of wheels locking up and skidding.

5. Blind Spot information system (BSIS)
Using cameras set just below the outer rear view mirrors the BSDS tell you if there is any vehicle in your blind spot.

6. Night Vision
Driving during the night becomes safe than ever with the night vision where one can see clearly on the control display even in pitch black. Thanks to infra red technology.

  1. If we want do this prjt how much it costs ?
    are we need a car for this prjt?

  2. hiii...i want to make this project as a part of an automobile related course which im doing...where can i get this project? plzz reply

  3. hello m anish i want to do this project.please tell me how much cost i invest in this project?????i want to know what are the instrument or equipments are requires to do this project.

  4. Great post..
