  • Purva Kini Umang Shah Durvas Mavalankar Meghal Dave
  • Contents Introduction What is a driverless car ? How will the car detect the traffic lights ? Technologies making a system fully autonomous A.N.V. Control of vehicle Automated Guided Vehicle Systems Advantages Disadvantages Conclusion
  • INTRODUCTION Driver error is the most common cause of traffic accidents India contributes 6 % of the world's road accident deaths Cell phones in-car ,entertainment systems, more traffic and more complicated road systems making it more frequent By this improving technology our car will do the concentrating for us.
  • What is a Driverless car ? It is a vehicle that can drive itself from one point to another without assistance from a driver; in other words, with an autopilot system
  • How will the car detect the traffic lights ? A sensor actinometer is used to detect the intensity of radiation Light of different colors will radiate different -2intensity of radiation Which will be detected by the sensor If the detected intensity is of red colour or yellow colour then controller will send a command to stop the vehicle . The command will be followed by robot(to convert the computer command into mechanical input)
  • Technologies making a system fully autonomous Anti-lock brakes(ABS) Electronic stability control (ESC) Cruise control Lane Departure Warning System Self Parking Automated Guided Vehicle Systems
  • Cars currently using Automotive Night Vision A.N.V. means:Increases a vehicle driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights. Current Active systems use an infrared light source 2002-2007 Lexus LX 470 2009 Lexus LS 2006 Mercedes CL-class 2009 Mercedes E-class 2005 Mercedes S-class 2009 Mercedes S-class 2008 Toyota Crown Hybrid 2002 Toyota Land cruiser Cignus
  • Control of vehicle As automotive technology matures, more and more functions of the underlying engine, gearbox etc. are no longer directly controlled by the driver by mechanical means. It is controlled via a computer, which receives instructions from the driver as inputs and delivers the desired effect by means of electronic throttle control. Therefore, the technology for a computer to control all aspects of a vehicle is well understood.
  • Automated Guided Vehicle Systems Uses FROG (Free Ranging On Grid) technology FROG vehicles are equipped with a computer that contains a map of the area
  • Advantages Managing traffic flow to increase road capacity. Relieving vehicle occupants from driving allowing them to concentrate on other tasks or to rest during their journeys. To avoid accidents . Increasing roadway capacity by reducing the distances between cars. The current location of vehicle can be determine using global positioning system (G.P.S) .
  • Disadvantages If the vehicle is using internet which is have less security then From the hackers point of view in some cases the vehicle can be switched off on the road(in rare cases) Hackers can change the rout which is plotted in the system(in rare cases) In case of failure of main sensor and backup sensors the vehicle can create a chance of accident
  • conclusion The driver less cars technologies improves vehicle's stability helps to minimize loss of control. Driver less cars are designed to minimize accidents by addressing the main causes of collisions: driving error, distraction and drowsiness.
  • News July 10, 2013 Griffith University students are using Smartphone technology to make the driverless car of the future more of a reality. June 27, 2013 BMW's driverless car takes to the public roads.
  • Future of Driverless Car July 2, 2013 Doctoral candidate Amol Khedkar is toiling on his own prototype for a software system that would let cars talk to one other, synchronizing their own movements. The vehicles could automatically change lanes and make turns without humans mucking things up
