BLIND SPOT DETECTION

While changing lanes on highways, we see the ORVMs of the required side. But, it isn't always enough. There is a spot behind your vehicle in which, if any vehicle is present, is not visible in the rear view mirror and this blind spot leads to many accidents and the driver of either vehicle can't be blamed for that. It's just a spot where ,if anything is present, is not visible to us, and interesting fact is that not many people are aware of that. Still, If side view mirrors on a car are adjusted in a particular way, there is no blind spot on the sides. But, most of the drivers aren't aware of this adjustment, infact, most of us don't even adjust our mirrors which clearly isn't a good practice.

Working:

Blind spot detection (BSD) was developed by Volvo a decade ago. BSD tracks traffic just behind you as well as what’s coming alongside. The alert stays active until the car in the adjacent lane is in front of you, or at least directly alongside and you’d have to be blind not to see it. It doesn’t care if you are in your lane or have drifted a bit into the next and are at risk of sideswiping another car. BSD uses ultrasonic or radar sensors on the side and rear of the car.

The visual alert is a yellow (usually) indicator in the side mirror glass, inside edge of the mirror housing, or on the A pillar inside the car. It lights when it senses a car in the blind spot and flashes if the turn signal is flashing. You’ll also get an audible alert (beeping) or an induced vibration or light shake of the steering wheel if the turn signal is flashing.

Is it worth?

Blind-spot monitoring is one of the most useful tools for keeping safe. If you pay attention to the audible or visual warnings, they can minimize your changes of merging into another vehicle. Systems with collision prevention functionality add further value to blind-spot monitoring because they actively steer or brake, adding another layer of security during your drive.
