Report on Driverless Cars: Technology, Safety, and Navigation - VIT

This report provides an overview of driverless car technology, emphasizing safety and navigation systems. It highlights the role of driver errors in road accidents and how driverless cars can mitigate these risks. The report details the necessity of systems like Mobileye NV sensors, wheel speed control, and steering-angle sensors. It also explains how driverless cars detect traffic lights using actinometers and radiation intensity. Furthermore, the report discusses key technologies such as anti-lock brakes, cruise control, self-parking, electronic stability control, and automated guided systems, explaining how each contributes to the safe and efficient operation of autonomous vehicles. The report concludes by emphasizing the importance of navigation systems in plotting routes and adapting to traffic conditions. This student contributed the document to Desklib, a platform offering a variety of study resources.

Driver less Cars

Introduction
Driver errors are the basic cause of road
accidents.
Approximately 6% of world’s people die
in road accidents annually.
Factors like entertainment systems, cell
phones, complicated road systems make
road accidents very frequent.
With the help of this technology cars are
able to concentrate for people.

Driver less cars
They can drive without any assistance.
It can drive safely by avoiding obstacles
on road.
It can move or stop according to the
traffic condition.
It accelerates to the appropriate speed
limit.

Necessity of the system
Sensors called mobileye NV
Sensors to control speed of wheels
Rotational-angle sensor
Steering-angle sensor
Operating the mechanics of the vehicle
Planning of motion
Navigation

Detection of traffic lights
A sensor called actinometer helps it to detect
the intensity of radiation
Different colored lights radiate different
radiation intensity
This intensity is detected by the sensor
If the detected color is yellow or red, a
command will be sent to robot to stop the car.

This is an example of
how driverless cars
detect radiations of
various colors and
operate in traffic.
This prevents the car
from facing accidents.

Technologies to be used
Anti-lock brakes
Cruise control
Ability to self park
Control of electronic stability
Guided system that is automated
Self parking

Anti-lock brakes
Brakes may lock up while braking hard,
anti-lock brakes prevent these
Anti lock brakes have
 Speed sensors
Pumps
Valves
Controller

Driverless cars detect
the cars around them
and use their smart
mechanism to avoid
accidents. They
maintain a certain
distance from other
vehicles.

Anti lock braking
system helps the
car to avoid
accidents by
applying brakes
when necessary

Automated cruise control
They use a laser or a radar setup
This allows the car to slow the speed when
in comes near other vehicle
The speed it again normal when the road is
clear
It maintains a safe distance from other
vehicles
Cruise control helps to keep the car a
constant speed

Adaptive Cruise Contro helps the car to
maintain a safe distance from other vehicles
in order to prevent acident.
