Working Principle of Blind Spot Detection
Technology in Cars
2
While driving a car, one of the most difficult
things is dealing with blind spots.
3
We all have side mirrors and rear view mirrors on
our cars, but these mirrors only give us a
limited vision of the other vehicles around us.
4
The drivers are forced to turn their heads
whenever theyre making a turn or changing lanes
to make sure that no other vehicles are
approaching from the side.
5
In order to avoid such inconvenience, blind spot
detection technology, is being integrated into
newer models to have complete 360-degree
detection around the car.
6
Working Principle
7
This technology contains sensors and cameras that
will detect when another vehicle is entering any
blind spot around your car.
8
For instance, if a vehicle approaches a blind
spot on the left side of your car, then the light
on your left side view mirror will start flashing.
9
And when you are attempting to change lanes, this
technology may warn you by vibrating your
steering wheel or causing a beeping sound to go
off.
10
Here are the important components of the blind
spot detection technology integrated into cars.
11
Rear View Cameras
12
The drivers mainly have problems with rear blind
spots when they try to back up or park in a space
behind them.
13
Some cars have rear-view cameras which provide a
video feed from directly behind the car and the
dashboard has a screen which shows you the video
in real time.
14
This means that you can just watch the screen in
front of you to check the rear blind spots.
15
Sensors and Sonars
16
The front and back of a car feature
electromagnetic sensors that can detect how close
other objects are to your vehicle.
17
Some versions of blind spot detection technology
use ultrasonic waves, which is referred to as
parking sonar to detect these objects.
18
Once an object is detected from these sensors or
sonars, you will be alerted through a light or
sound turning on.
19
Lane Departure Warning Systems
20
A lot of accidents occur because drivers weave in
and out of their lanes because theyre
intoxicated or simply distracted on their mobile
phone.
21
The latest blind spot detection technology has a
lane departure warning system as it is dangerous
on the interstate roads where driving speeds are
faster.
22
This features cameras that are placed on the side
view mirrors which can detect how close the
vehicle is to the white line on the side and if
it gets too close, the driver gets alerted.
