This document discusses autonomous vehicles and the technologies enabling them. It describes how vehicles can detect traffic lights using sensors to read light intensities and how controllers command stops. Technologies like ABS, automatic braking, electronic stability control, and cruise control with distance monitoring help vehicles drive themselves. The document outlines how self-parking vehicles use sensors and screens to navigate into spaces and how automated guided vehicles rely on onboard maps. While autonomous vehicles could improve traffic and safety, challenges include hacking and sensor failures potentially causing accidents. The future applications of this technology are also explored.
Auto pilot technology in vehicles
- 1. PRESENTED BY: CHINTHAGUMPALA.PRAVEEN REG.NO:14HN1A0314 BRANCH:MECHANICAL GUIDED BY : Asst.Prof .P.SURESH, M.TECH Dept.of Mechanical engineering ,AECN,SPSR NELLORE
- 2. Contents • Introduction • What is auto pilot vehicle? • How will the vehicle detect the traffic lights • Technologies making a system fully autonomous • Control of vehicles • Automated guided vehicle systems
- 3. Prototypes of autopilot vehicles
- 4. INTRODUCTION • Driver error is the most common cause of traffic accidents • India contributes 6% of the world’s road accidents deaths • Mobiles in-car ,entertainment systems ,more traffic and more complicated road systems making it more frequent • By this improving technology our car will done the concentrating for us.
- 5. What is driverless vehicle? • It is a vehicle that can drive it self from one point anther without assistance from a driver; in other words, with an auto pilot system
- 6. How will the vehicle detect the traffic lights? • A sensor “actinometer” is used to detect the intensity of radiation • Light of the different colors will radiate different -2- intensity of radiation • Which will be detected by the sensor • If the detected intensity is of red colour or yellow colour then controller will command to stop the vehicle. • The command will be followed by a robot(to convert the computer command into mechanical input)
- 7. Technologies making a system fully autonomous
- 8. Anti-lock brakes system (ABS) • An ABS generally offers improved vehicle control and decreases stopping distances on dry and slippery surfaces for many drivers
- 9. Parts of (ABS) • Speed sensors • Valves • Pumps • controller
- 10. Automatic braking • Senses an imminent distance with another vehicle or a velocity related danger. • Responds by either precharging the brakes or by approaching the brakes to slow the vehicle without any driver input. • Detects by radar , video, infrared, ultrasonic, gps sensors. • Introduced by toyota.
- 11. Electronic stability control (ESC)
- 12. Components
- 13. Cruise control • Cruise control keeps the car at a constant speed by taking over the throttle of the car. • It also maintain a set distance between it and the car in front of it.
- 14. Self-parking vehicles • System uses sensors all around the car to guide it into a parallel parking space • Lexus LS 460 L with Advance parking guidance system • The driver has to find a parking space, • Position the vehicle next to it, and use the in- cabin navigation screen to tell the car where it should go. • The parking space needs to be 6 feet longer than car.
- 16. Backup camera & parking sensors • Special type of video camera attached to the rear of a vehicle to aid in backing up. • Parking sensors are proximity detectors which can alert the driver to unseen obstacles during parking.
- 17. Control of vehicle • As automotive technology matures, more and more functions of the underlying engine, gear box etc. are no longer directly controlled by the driver by mechanical means.
- 18. Automated Guided Vehicle System • Uses FROG (free Ranging on grid) technology. • FROG vehicles are equipped with computer that contains a map of the area.
- 20. 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 avoided 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).
- 21. 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 route 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
- 22. FUTURE
- 23. APPLICATIONS
- 24. Conclusion • The driver less car’s are 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.
