  INTRODUCTION • Road accidentshas been a major problem as the vehicle compactness on the road increased dramatically due to the growth of population and the improvement in living standard. • Road accidents mainly occur due to carelessness, fast driving, drunken driving etc. • In this project a system is implemented which reduces the accidents to an extent. • An ultrasonic sensor is used, which detects the obstacles in its path and providing the nearness to the obstacle.
• 4.
  Future Scope • Steeringwheel , the only control to vehicle. • Automatic acceleration & deceleration. • Proximity detection as anti-collision system in trains.
• 5.
  EXISTING SYSTEM Conventional typesof automobile braking techniques: • Drum braking • Hybrid braking • Electromagnetic braking • Anti brake locking system(ABS)
• 6.
  PROPOSED SYSTEM • Micro-controllerbased Automatic braking system. • Employs an ultrasonic sound sensor. • Atmega328A-PU on Arduino Uno development kit used. • DC motor rotation represents motion of the vehicle, LEDs denote the brake light.
• 7.
  DRAWBACKS OF EXISTINGSYSTEM • Depends on human responsiveness. • Negligence can lead to accident. • Does not ensure total security.
• 8.
  ADVANTAGES OF PROPOSEDSYSTEM • Low cost. • Easy to implement. • Excellent response to obstacles. • Driving becomes easier.
• 9.
  FRONT END • Ultrasensor Model:HCSR04 interfaced with Arduino. • The sensor is placed on the bumper of the vehicle.
• 10.
  BACK END • ATMEGA328A-PUMICRO-CONTROLLER • LED-Light Emitting Diode; a p-n junction diode emitting light. • DC Motor; which works on the attracting and repelling property of magnets. Dual shafted motor used.
