BLIND SPOT DETECTION

BLIND SPOTAblind spotin 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 thewindow pillars, headrests, passengers, and other objects.

CONSEQUENCES OF BLIND SPOTvehicular blind spot exists in the space between the driversperipheral visionand 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 accidentsThe 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 DETECTIONBlind 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 drivers view. So that accidents can be avoidedAnd 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 drivers seat.

WORKING OF SENSORSThese 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 drivers attention and judgement.Do not rely solely on the system. Always be vigilant when driving.Drivers are encouraged to read the owners manual to become familiar with the system and the conditions when system operation is different or is not guaranteed.

Does Blind Spot Detection Really Work?

According to the HighwayLoss Data Institute, there isnt 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 doesnt 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 backup sonar.

Annoying? Then turn it off

As for the complaint about annoying blinking lights, on most cars thats only when you have your directional on; when its 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 youve 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
