2. OVERVIEW Introduction DSRC VANET Need for V2V V2V for safety Hazard warning Accident warning Emergency vehicle warning Traffic signal violation warning Features Advantages & Disadvantages Future Conclusion 11/3/2020 2 PSG COLLEGE OF TECHNOLOGY

3. INTRODUCTION Vehicle-To-Vehicle (V2V) is an automobile technology designed to allow automobiles to "talk" to each other i.e., to communicate with each other It is worked on base of Dedicated Short Range Communications(DSRC) 11/3/2020 3 PSG COLLEGE OF TECHNOLOGY

4. Contd.. This systems are an emerging types of networks in which vehicles and roadside units are the communicating nodes To provide each other as information, such as safety warning and traffic information. Generally vehicular networks are considered to contain two types of nodes: vehicle to vehicle (V2V) vehicle to Roadside (V2R) 11/3/2020 4 PSG COLLEGE OF TECHNOLOGY

5. Contd.. Mainly it is motivated by ITS(Intelligent Transport System) According to World Health Organizations (WHO), road accidents annually cause approximately 1.2 million deaths worldwide Also about 50 million persons are injured in traffic accidents Western Europe a mere 5 km/h decrease in average vehicle speeds could result in 25% decrease in deaths V2V is nothing about full mesh topology. In a full mesh topology, each network node is connected directly to each of the others 11/3/2020 5 PSG COLLEGE OF TECHNOLOGY

6. DSRC DSRC is a multi-channel wireless standard that based on the IEEE 802.11a PHY and the IEEE 802.11 MAC. It is targeted to operate over a 75 MHz licensed spectrum in the 5.9 GHz band It is designed to facilitate communication at distances of up to 1 km. 11/3/2020 6 PSG COLLEGE OF TECHNOLOGY

7. Contd.. The new tech combines Wi-Fi and GPS to create a new form of communication known as DSRC. The data exchanged may include a vehicle’s position, speed, steering angle, brake status, turn signal status, number of people in the vehicle, etc. 11/3/2020 7 PSG COLLEGE OF TECHNOLOGY

8. Contd.. The system works by making each vehicle a node on the network. Bandwidth:75MHz (5.850 –5.925GHz) Modulation : QPSK OFDM Channels:7 channels Data Rate:1-54Mbps Max Range:1000m Min. Separation:10m 11/3/2020 8 PSG COLLEGE OF TECHNOLOGY

9. VANET Vehicle Ad hoc Networking VANET is a technology that enables communication over multiple wireless hubs, but not necessarily including roadside access points. VANET integrates on multiple ad-hoc networking technologies such as WiFi IEEE 802.11p, WAVE IEEE 1609, WiMAX IEEE 802.16, Bluetooth etc 11/3/2020 9 PSG COLLEGE OF TECHNOLOGY

10. Contd.. The onboard sensors readings displayed to the drivers via monitors to be aware of the vehicle condition or emergency alarms, and also can be broadcasted to the other adjacent vehicles. 11/3/2020 10 PSG COLLEGE OF TECHNOLOGY

11. NEED FOR V2V To reduce the accidents. To reduce the time of travel. Extended driving vision. To help others in making their drive comfort. 11/3/2020 11 PSG COLLEGE OF TECHNOLOGY

12. V2V FOR SAFETY By exchanging anonymous: over vehicle-based data regarding position, speed, and location Enables a vehicles to: Sense threats and hazard with a 360 degree awareness of the position of other vehicles Issue driver advisories or warnings Take preventive actions to avoid and mitigate crashes. 11/3/2020 12 PSG COLLEGE OF TECHNOLOGY

13. 1.Hazard Warning Vehicles that are in a traffic jam and turned on their hazard warning lights, communicate this information back to other vehicles. Information is much more accurate and reaches upcoming traffic. 11/3/2020 13 PSG COLLEGE OF TECHNOLOGY

14. 2.Accident Warning If vehicles involved in an accident are equipped with short-range communication, they can send out a warning message to the following traffic e.g. to avoid mass collisions. If the driver fails to take action, the V2V system could automatically apply the brakes to stop the car. 11/3/2020 14 PSG COLLEGE OF TECHNOLOGY

15. 3.Emergency Vehicle Warning Approaching emergency vehicles send out a warning message to warn vehicles that are in its vicinity Receiving vehicles can automatically mute the radio or the hands free-phone and give an audible or visual warning message to the driver 11/3/2020 15 PSG COLLEGE OF TECHNOLOGY

16. 4.Traffic Signal violation Warning Vehicles can be warned about an imminent change of a traffic light and if they are in danger of running a red light Traffic lights can send out their timing and phase to prevent red light violations and potential accidents 11/3/2020 16 PSG COLLEGE OF TECHNOLOGY

17. FEATURES The main features are Speed of the vehicle Break status Path history Path indication 11/3/2020 17 PSG COLLEGE OF TECHNOLOGY

18. Contd.. The other features are: It gives the indication in the form of vibrating the seat, voice or display. It specifies the features for a range of 1000m The personal information will not be revealed Emergency electronic break light warning(if there is sudden braking from the front vehicle) Blind spot warning Signal timing and phase are known 11/3/2020 18 PSG COLLEGE OF TECHNOLOGY

19. Contd.. Road weather indications The weather data will be collected from the drivers and will be sent to TMC’s and then the operates specify about the weather of the roads With the help of this systems people can know the traffic updates from the home easily If there is any car crashes ,police activities or ambulance activities are present people can know it from V2V so that they can give way for them 11/3/2020 19 PSG COLLEGE OF TECHNOLOGY

20. ADVANTAGES By this technology, people’s drive will be more comfortable and easier The case of accidents will be very less Any problem occurred by one in driving will be informed to others so they can be aware of it while driving 11/3/2020 20 PSG COLLEGE OF TECHNOLOGY

21. DISADVANTAGES Any small occur in the working of V2V will leads to the total disturbance of the one’s driving Some times signals given by it will not be correct 11/3/2020 21 PSG COLLEGE OF TECHNOLOGY

22. FUTURE At present, development of first generation of V2V systems is underway. Function of these systems is limited only up to giving warning to the driver. However, these systems are unable to take any corrective action in the input given by the driver The second generation of Vehicle to Vehicle systems would be able to take control of the vehicle in danger and provide the corrective action. These systems would ultimately merge with the autonomous driving technology 11/3/2020 22 PSG COLLEGE OF TECHNOLOGY

23. CONCLUSION The technology of the V2V is one of the boon to the automobile industry and the people. As if now it is a prototype. It will be more easier and helpful once it came to existence for the people for their smooth drive experience. 11/3/2020 23 PSG COLLEGE OF TECHNOLOGY
