INTRODUCTION

• Autonomous vehicle

• Automated guided vehicle (AGV).

• Devoleped by Google engineer Sebastin and team• (won the 2005 DARPA Grand Challenge)

• On May 28, 2014, Google presented a new prototype of their driverless car .

History

Sebastian Thrun invented the

Google driverless car

prevent traffic accidents, free up

people’s time and reduce carbon

emission by fundamentally

changing car use”-Sebastian Thrun

The Google Driverless car was

tested in the year 2010

Behind the technology

1. Daily accidents2. For aged persons3. Fuel consumption

Features

• G P S

• Automatic steering

• Automatic parking

• Safety

COMPONENTS

• LIDAR SENSOR

• RADAR SENSOR

• VIDEO CAMERA

• POSITION ESTIMATOR

LIDAR SENSOR “The heart of the system”

The LIDAR (Light detection

and Ranging) sensor is a

scanner

scanner contains 64 lasers

that are send to

surroundings of the car

through the air

“The heart of the system generates a detailed 3D map of environment (velodyne 64- beam laser).

The map accessed from the GPRS connection .

RADAR SENSOR Three RADAR sensors are

fixed in front of the bumper

and one in the rear bumper

measures the distance to

various obstacles and allow

the system to reduce the

speed of the car

The back side of sensor will

locate the position of the car

on the map

VIDEO CAMERA

video camera is fixed near the rear view mirror

detects traffic lights and any moving objects in front of the car

done by the artificial intelligence software.

POSITION ESTIMATOR

A sensor mounted on the left

rear wheel

measures small movements

made by the car and helps to

accurately locate its position

on the map

The position of the car can

be seen on the monitor.

ARTIFICIAL INTELIGENCE

Google maps and the hardware sensor data are sent to the AIAI Then determines: How fast to accelarate When to slow down/stop When to steer the wheelGoal of AI: The agent’s goal is to take the passenger to its desired destination safely and legaly

Working of Driverless car

SENSING AND SENSOR FUSION

AUTOMATED HIGHWAY SYSTEMS (AHS)

construct special lanes on existing highways

magnets or other infrastructure to allow vehicles to stay in the center of the lane .

A central system communicating with other vehicles to avoid collision and manage traffic.

ADVANTAGES

• Saving parking places

• Efficient use of highways

• Optimal speed

• Avoid accidents

CONCLUSION

• It is a latest technology.Google driverless car driven 230,000 km without any incidents .In 2008, begin testing driverless cars and they could be on the road by 2018.
