Advantages

Disadvantages

Driver error is the most common cause of traffic accidents

India contributes 6 % of the world's road accident deaths

Cell phones in-car ,entertainment systems, more traffic and more complicated road systems making it more frequent

Drowsiness of the driver and failure in taking sudden decisions adds up to the factors .

The fully autonomous cars posses the technology which drives it the safest way possible and have been proved successful in this context till now

The first known worthy attempt to build an autonomous vehicle was in 1977.

The project research was carried out by Tsukuba “Mechanical Engineering Laboratory” in Japan.

The breakthrough in the development autonomous vehicles came in the 1980’s with the work of “Ernst Dickmanns” and his team at Bundeswehr Universitäty.

An autonomous car is also known as autonomus car , Self-Driving Car & Robot Car.

It is a vehicle that can drive itself from one point

to another without Assistance from a driver.

in other words, It is operated by an autopilot system.

The passenger just has to feed in the destinations

he want to reach and the car will take him to the

destination .

Google MapsProvide the car road information SensorProvide the car with real time environment conditionArtificial IntelligenceProvide the car with real time decisionRadaris 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.Lidaris a remote sensing technology that measures distance by illuminating a target with a laser and analyzing the

reflected light.

Working:

Sensors

Navigation

Motion planning(traffic)

Actuation(operates the mechanics of vehicle)

Sensors employed in driverless cars are called mobileye N.V

Mobileye offers a wide

range of driver safety

solutions combining

artificial vision image

processing, multiple

technological applications

and information technology

Wheel speed sensors

Steering-angle sensors

Rotational-speed sensor

A sensor “actinometer “ is used to detect the intensity of radiation

Light of different colors will radiate different -2-intensity of radiation

Which will be detected by the sensor

If the detected intensity is of red color or yellow color

The controller will send a command to stop the vehicle

The command will be followed by robot(to convert the computer command into mechanical input)

Anti-lock brakes(ABS)

Cruise control

Self Parking

Automated Guided Vehicle Systems

While braking hard without anti-lock brakes, the wheels

can lock up, sending the car into an out-of-control skid.

and the driver has to pump the brake pedal to keep the

wheels from locking up

With anti-lock brakes, the system does the pumping for

the driver - and does it better than the driver. The system

can read the wheels and knows when they are about to

lock and react faster

Autonomous cruise control is an optional cruise control system appearing on some more upscale vehicles. These systems use either a radar or laser setup allowing the vehicle to slow when approaching another vehicle and accelerate again to the preset speed when traffic allows

It also maintain a set distance between it and the car in front of it

Cruise control keeps the car at a constant speed

Automated Guided Vehicle Systems

Uses FROG (Free

Ranging On Grid)

technology

FROG vehicles are

equipped with a

computer that

contains a map of

the area

The ability to plot the rout from where the vehicle is to where the user wants to be has been available for several years

the more sophisticated system also receives radio updates on road blockages, and adapt accordingly

is a term used in robotics for the process of detailing a task into discrete motions.

It should execute this task while avoiding objects like other cars.

managing traffic flow to increase road capacity.

relieving vehicle occupants from driving and navigating chores, so allowing them to concentrate on other tasks or to rest during their journeys.

to avoid accidents

increasing roadway capacity by reducing the distances between cars

The current location of vehicle can be determined using global positioning system(G.P.S)

If the vehicle is using internet which is have less security then From the hackers point of view in some cases the vehicle can be switched off on the road(in rare cases)

Hackers can change the rout which is plotted in the system(in rare cases)

In case of failure of main sensor and backup sensors the vehicle can create a chance of accident
