Self driving cars
- 1. 1 17-08-2017 SELF - DRIVING CARS
- 2. Introduction:- A self driving car is a vehicle that is capable of sensing its and navigating without human input. Also known as:- 17-08-2017 2 Autonomous Cars Robotic Cars Driverless Cars Google and its team of Engineers is out with yet another wonder. The Driverless Car:::::: Image source :- Google
- 3. 17-08-20173 Google self -driving car is a project by Google that involves developing technology for autonomous cars. The self-driving car is like any car, but It can steer itself while looking out for obstacles. It can accelerate itself to the correct speed limit. It can stop and go itself based on any traffic condition.
- 4. 17-08-2017 4 The Google team has been working on their self driving car project since 2009, in 2012 they began testing with the Lexus RX450h on freeways then focused to city streets these models Available in dual mode, auto driving and manual. In 2014 the Google team unveiled an early construction of their new prototype that is fully self driving. Google will release its first model in market in 2018. Other companies also announce their driverless cars like Nissan announces that they will launch their car in 2020. Image source :- Google
- 5. According to a report nearly 1.3 million people die in road accidents every year, average 3287 peoples daily. 94% of the accidents involve human error. It can be reduce with self driving car. It allow driving to those people who are blind and some other kind of physical disability. It can provide more time for us to work , read books , watch movies , chat with families & friends. 17-08-2017 5

- 8. 17-08-2017 8 How It works:- Self-Driving Cars use their sensors and software to sense objects like pedestrians, cyclists, vehicles and more, and are designed to safely drive around them. Like any driver, a self-driving car needs to constantly answer these questions - Where am I ? What’s around me ? What will happen next ? What should I do?

- 11. 17-08-2017 11 HARDWARE SENSORS :- LIDAR VIDEO CAMERA POSITION ESTIMATOR DISTANCE SENSOR
- 12. 17-08-2017 12 LIDAR :- Heart of this system. Stands for LIght Deduction And Ranging It is a remote sensing method used to examine the surface of the Earth. It uses light in the form of pulsed laser , these light pulses combined with other data measure by airborne system and generate precise 3D information about the shape of earth and its surface characteristics. Range:- 60 metre Image source:- icdn4..digitaltrends.com
- 13. 17-08-2017 13 VIDEO CAMERA :- It detects upcoming traffic light and road signs as well. POSITION ESTIMATOR (wheel encoder/ultrasonic sensor):- It determine vehicles location and keeps track of its movements. DISTANCE SENSOR:- It allow the car to see far enough to detect nearby or upcoming cars or obstacles.
- 14. 17-08-2017 14 ARTIFICIAL INTELLIGENCE:- Google Maps and the hardware sensors data are sent to the AI. AI then determines : How fast to accelerate. When to slow down / stop. When to steer the wheel etc. Goal of Artificial Intelligence: The agents goal is to take the passenger to its desired destination safely and legally.
- 15. 17-08-2017 15 Where they are:- They’ve self – driven more than 1.5 million of miles and are currently out on the streets of Mountain view , CA , Austin , Kirkland , WA etc. Currently 30 companies working on self-driving cars including BMW ,Audi ,Volkswagen ,Volvo ,Nissan ,Ford and so on... In 2025 the self driving car will be available in all over the world.
- 16. 17-08-2017 16 SAFETY:- Humans are not good at driving 1.3 million people killed every year on roads worldwide are a proof of that. Unlike us:- It will not be able to speed as its speed limit is 25miles /hour. It will never drive drunk and with lack of concentration. It will never get angry ,frustrated and competitive. Emergency stop button that user can hit at any time The car will wait a second after the traffic lights turn green before it moves off.
- 17. 17-08-2017 17 Benefits:- It is safer than a human driver. It is air pollution free. No need of driving license , anybody can drive even a child can use it for go to school or coaching or for other activities. Time saving. Police officer focus could be shifted from writing traffic tickets and handling accidents to managing other, more serious crimes. There are no opportunities for a computer to be "distracted", which is a leading cause of accidents.
- 18. 17-08-2017 18 Drawbacks:- High cost. Security issue.(Hackers are so much interested) Self-driving cars would eliminate many jobs in the transportation sector. Who holds responsibility in a car accident- the driver? The car manufacturer? The software developer? Self-driving cars would be great news for terrorists, as they could be loaded with explosives and used as moving bombs. Increase Laziness.
- 19. 17-08-201719 Accidents:- In the journey of 1.5million miles Google has reported 18 total number of accidents. All these accidents are minor as nobody is hurt in these accidents. Many of these cases are very small like the car Impinge with divider , police stop sign etc. One of the case of February 2016 is major in all these accidents when a car hit a bus , 16 passengers are there in bus and no driver in the car as it is on trial but nobody injured during all this.
- 21. 17-08-2017 21 Conclusion:- Technology always comes with many advantage and some disadvantages also , it is quite interesting to see how the world will actually become With self driving car but one thing is sure that humans are not good at driving so self driving car can play an important role to decrease the number of accidents.
