GOOGLE SELF DRIVING CAR TECHNOLOGY PRESENTED BY : AKHIL SAJU S5 CT ROLL NO. - 09

INTRODUCTION • D.L Hendricks for National Highway traffic Safety Association

• To determine the specific driver behaviours • Out of 723 crashes investigated, driver behavioural error caused or contributed 99% (717) to the crash. They are

• DRIVER INATTENTION - 22.7%, • VEHICLE SPEED - 18.7%, • ALCOHOL IMPAIRMENT - 18.2%, • PERCEPTUAL ERRORS (e.g. looked, but didn’t see) - 15.1%, • DECISION ERRORS (e.g. turned with obstructed view) 10.1%, • INCAPACITATION (e.g. fell asleep) - 6.4%.

INTRODUCTION (CONTD..) •GOOGLE SELF DRIVING CAR

•project by Google - involves developing technology

for autonomous cars. •Software powering Google's cars - Google Chauffeur. •currently led by Google engineer Sebastian Thrun. •Thrun's team at Stanford created the robotic vehicle Stanley which won the 2005 DARPA Grand Challenge and its US$2 million prize from the United States Department of Defense .

WHAT KIND OF CARS HAS GOOGLE BEEN USING?

Toyota Prius

Audi TT

Google Car

Lexus RX 450h

WHAT ARE THE PARTS? • LIDAR • Video Camera • Position Estimator • RADAR

WHAT DOES THE CAR LOOK LIKE?

LIDAR • also written LIDAR, LiDAR or LADAR • remote sensing technology that measures distance by illuminating a target with a laser and analysing the reflected light.

• Lidar

is popularly used as a technology to make high-resolution maps.

HOW TO OPERATE SELF DRIVING CAR? • The “driver” sets a destination. The car’s software calculates a route and starts the car on its way.

• A rotating, roof-mounted LIDAR (Light Detection and Ranging - a technology similar to radar ) sensor monitors a 60-meter range around the car and creates a dynamic 3D map of the car’s current environment.

• A sensor on the left rear wheel monitors sideways movement to detect the car’s position relative to the 3-D map.

• Radar systems in the front and rear bumpers calculate distances to obstacles.

HOW TO OPERATE SELF DRIVING CAR? • Artificial intelligence (AI) software in the car is connected to all the sensors and has input from Google Street View and video cameras inside the car.

• The AI simulates human perceptual and decision-making processes and controls actions in driver-control systems such as steering and brakes.

• The car’s software consults Google Maps for advance notice of things like landmarks and traffic signs and lights.

• An override function is available to allow a human to take control of the vehicle.

ARE THEY BETTER THAN REGULAR CARS? • React faster than humans • 360 degree perception • Cannot get distracted, sleepy, or intoxicated • Actively engage the driver (announcements like “approaching a crosswalk” or “turn ahead”)

• Driver could regain power by hitting a red button (override) on dashboard, touching the break, or turning the steering wheel

WHERE IT HAS BEEN LEGALISED?

•

Legal to use an autonomous car on public roads

ROAD TESTING • Google's vehicles have traversed  • • • •

San Francisco's Lombard Street through city traffic. over the Golden Gate Bridge and around Lake Tahoe. The system drives at the speed limit it has stored on its maps and maintains its distance from other vehicles using its system of sensors. 4,82,803 kms - just 2 accidents – minor intensity

IS IT WORTH IT? ADVANTAGES
