INTRODUCTION
A driverless car are also called automated car or robotic vehicle or self-driving car .
That is designed to travel between destinations without a human interaction.
To qualify as fully autonomous, a vehicle must be able to navigate without human intervention to a predetermined destination over roads that have not been adapted for its use.

COMPONENT USE
Google Maps
Provide the car road information
Sensor
Provide the car with real time environment condition
Artificial Intelligence
Provide the car with real time decision
Radar
is an object-detection system that uses radio waves to determine the range, altitude, direction, or speed of objects
Global Positioning System
GPS) is a space-based Satellite navigation system that provides location and time information in all weather conditions.
Lidar
is a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the reflected light.

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.
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 signals and lights.

The would eliminate accidents caused by driver error
The greater precision of an automatic system could improve traffic flow.
Dramatically increase highway capacity and reduce or eliminate traffic jams.
Finally, the systems would allow commuters to do other things while traveling, such as working, reading or sleeping.
