The document discusses the key features and technologies of driverless cars. It describes how sensors detect traffic lights and obstacles, allowing the car to brake automatically and park itself without human input. The document also covers potential advantages like increased road capacity and safety, though hacking of internet-connected systems poses rare risks. In summary, driverless cars use sensors and computers and to navigate and brake autonomously, aiming to reduce accidents through features that can replace human control, perception and error.

2.  Introduction
 What is a driverless car ?
 Features of car.
 Technologies making a system fully autonomous.
 Adavantage
 Limitation

3. What is a driverless car ?
It is a vehicle that can drive itself from
one point to another without assistance
from a driver; in other words, with
an autopilot system

5.  Detection of traffic light automatically.
 A.N.V( automated night vision)
 Back up camera & parking sensor
 Automatic brake
 Self parking.

6.  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 colour or yellow
colour then controller will send a command to stop
the vehicle .
 The command will be followed by robot(to convert
the computer command into mechanical input)

7.  increases a vehicle driver's perception and seeing distance
in darkness or poor weather beyond the reach of the
vehicle's headlights.

8.  Special type of video camera attached to the rear of a
vehicle to aid in backing up.
 Parking sensors are proximity detectors which can alert
the driver to unseen obstacles during parking.

9.  Senses an imminent
distance with another
vehicle or a velocity
related danger.
 Responds by either
precharging the brakes or
by applying the brakes to
slow the vehicle without
any driver input.
 Detects by radar, video,
infrared, ultrasonic, GPS
sensors.
 Introduced by Toyota.

10.  System uses sensors all around the car to guide it into a
parallel parking space
 Lexus LS 460 L with Advance Parking Guidance System
 The driver has to find a parking space,
 Position the car next to it, and use the in-cabin navigation
screen to tell the car where it should go.
 The parking space needs to be 6 feet (1.8 meters) longer
than the car

12.  Anti-lock brakes(ABS)
 Electronic stability control
(ESC)
 Cruise control
 Lane Departure Warning
System
 Automated Guided Vehicle
Systems

13.  An ABS generally offers improved vehicle control and
decreases stopping distances on dry and slippery surfaces
for many drivers.

14.  Speed sensors
 Valves
 Pump
 Controller

15.  A computerized
technology improves
vehicle's stability by
detecting and minimizing
skids.
 Automatically applies the
brakes.
 Helps to minimize a loss of
control.
 ESC compares the
driver's intended direction
to the vehicle's actual
direction

16.  Wheel-speed sensors
 Steering-angle sensors
 Rotational-speed sensor

18.  Cruise control keeps the car at a constant speed by taking
over the throttle of the car
 It also maintain a set distance between it and the car in
front of it

19.  A mechanism designed to
warn a driver when the
vehicle begins to move out
of its lane
 Designed to minimize
accidents by addressing
the main causes of
collisions: driving error,
distraction and
drowsiness.

20.  Uses FROG (Free
Ranging On
Grid) technology
 FROG vehicles
are equipped
with a computer
that contains a
map of the area

21.  Managing traffic flow to increase road capacity.
 Keeping the driver relax.
 To avoid accidents .
 Increasing roadway capacity by reducing the distances
between cars.
 The current location of vehicle can be determine using
global positioning system (G.P.S) .
 Providing high security to vehicles

22.  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

23.  The driver less car’s technologies improves vehicle's
stability helps to minimize loss of control.
 Driver less cars are designed to minimize accidents by
addressing the main causes of collisions: driving error,
distraction and drowsiness.
