BLIND SPOT DETECTION

PRESENTED BY:

MUMAL RATHORE

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.

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

accidents

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.

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.

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

.

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

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.

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.

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.

RANGE OF BLIND SPOT

DETECTION

This is much easier to explain

through a visual than through

words alone

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.

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

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.

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

and more insistent that

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.

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.

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
