BLIND SPOT DETECTION

1. BLIND SPOT DETECTION

2. BLIND SPOT
 A blind spot in a vehicle is an
area around the vehicle that
cannot be directly observed
by the driver while at the
controls, under existing
circumstances.
 Blind spots exist in a wide
range of vehicles: cars,
trucks, motorboats, sailboats.
and aircraft.
 Blind spots can be caused by
the window pillars, headrests,
passengers, and other
objects.

3. CONSEQUENCES OF BLIND SPOT
 vehicular blind spot exists in
the space between the
driver’s peripheral vision and
the area reflected by the
rear-view mirrors.
 This type of blind spot can
swallow up entire vehicles,
which is why it's so
dangerous to change lanes
without looking to the left or
right.
 And finally leads to

4.  Every year, a large number of
accidents take place due to blind
spots.
 Although the mortality rate of these
accidents is just 1% which is low
compared to other accidents
 The extent of injury and property
damage is high.
 Therefore, lane-change blind-spot
accidents remain a cause of great
concern.

5. How Can Technology Help Remove
Blind Spots?
 Mirrors can help remove blind spots behind a
driver, but they typically leave large dead areas
to both sides of a vehicle.
 The addition of a convex blind spot mirror can
allow a driver to see objects that fall into that
type of blind spot, but those images are
distorted and can make it difficult to judge
distances.
 It is also illegal to even install a blind spot mirror
in some jurisdictions.

7. Due to the errors caused by
humans in arranging the mirrors
,and distorted images obtained
by the convex mirrors leads to a
new technology called BLIND
SPOT DETECTION
.

8. BLIND SPOT DETECTION
 Blind Spot Detection
systems warn a driver
that a vehicle is in his or
her blind spot –areas to
the side and rear of the
vehicle outside the
driver’s view.
 So that accidents can
be avoided
 And due to it changing
of lane will be easier
and safetly

9.  Sensors (camera,
ultrasonic, or radar)
monitor the sides and
rear of the vehicle for
vehicles (including
motorcycles)
approaching from
behind and alert the
driver with lights
mounted in either the
side-view or rear-view
mirrors, or the door.

10. If you switch on a turn signal showing intent to
make a lane change, and a vehicle is present in
the blind spot, the system may warn you with red
or yellow flashing icons and/or audio alerts, or by
vibrating the steering wheel or the driver’s seat.

11. WORKING OF SENSORS
 These sensors continuously monitor the
velocity and direction of the vehicle to
obtain a digital picture of the vehicle's
environment. The warning indicator is
switched on when the vehicle
approaches the blind spot. The system
also emits an audio alarm to give an
additional warning.

12. RANGE OF BLIND SPOT
DETECTION

13. This is much easier to explain
through a visual than through
words alone

14. Things to keep in mind
 These systems are designed to aid in the driving task.
They are not intended to replace the driver’s attention
and judgement.
 Do not rely solely on the system. Always be vigilant
when driving.
 Drivers are encouraged to read the owner’s manual to
become familiar with the system and the conditions
when system operation is different or is not
guaranteed.

15. BLIND SPOT MONITOR
 A blind spot monitor is a vehicle-based sensor device
that detects other vehicles located to the driver’s side and
rear. Warnings can be visual, audible, vibrating or tactile

16. Does Blind Spot Detection Really
Work?
 According to the Highway Loss Data Institute,
there isn’t enough data to determine whether
blind spot detection results in fewer accidents.
 Common sense indicates that the technology
should help drivers avoid accidents, but real life
data doesn’t always line up with expectations.
 As only few cars are having this technology.

17. What else can blind spot detection do?
 If you have blind spot
detection, the sensors
may also provide
cross-traffic alert.
 When you start to back
out of a head-in
parking spot with cars
on either side, the
sensors will notice
traffic on either side
heading in your
direction and sound an
alert, usually louder

18. Annoying? Then turn it off
 As for the complaint about annoying
blinking lights, on most cars that’s only
when you have your directional on;
when it’s off, you got a non-blinking
light that is no more distracting than
others on the dash or instrument panel.

19. Should you buy? Yes, if you can afford
the package
 Safety groups almost all believe you
should have blind spot detection. Between
blind spot detection and lane departure
warning, if you’ve only got money for one,
you may find more safety group preference
for BSD.

20. FUTURE DEVELOPMENT
The blind-spot detection device developed by
Advanced technology products of Toronto,
Ontario, employs a patented passive infrared
sensor technology that can sense thermal energy
released from the tires of the vehicle while
moving.
 The temperature difference is used for turning on
the red light to warn the driver. Most of the
automobile manufacturers consider employing
radar-based sensors as these radars cover a
wide area from the vehicle's side to the rear and
have the potential to differentiate mobile and
stationary objects
