Blind spots are one of the main reasons of accidents these days. Practically, a blind spot is an area around the vehical which can’t be observed or seen directly by the driver he is driving the car. In other words, blind spots are the different areas in the lane of traffic beside our vehicle which are hidden by different structures of the vehicle. Almost all the vehicles have blind spots including trucks, cars, motorboats and aircraft etc. There are three major kinds of blind spots in an automobile. First is between the front door and the windshield, second is behind the front door and third is the area ahead of the windshield on the rear side of the vehicle.
BSD (Blind spot detection systems) began to appear for the first time in top-most-line consumer vehicles in the year 2005 with Volvo initiating and leading the way. Such systems became available in the high-volume models of Mercedes Benz E-Class and 2012 Ford Focus from previous year onward. In its early days this technology has struggled a lot for recognition as a standalone gadget, more or less because it was being said that this feature is for drivers who are less competent. Something same like so call “cool” riders never wear helmet and show off their riding skills or wear a no-grade helmet which is not at all good for safety. However, now this feature is more popular because it has been better understood that this is a device which is necessary for safety of life, health and vehicle.
Now in the modern era the BSD has come in a combined package of camera, ultrasonic systems and radar sensors to feed information to the warning systems. Cameras fitted in the front bumper of the vehicle send live feed inside the vehicle to the display screen. In case of an approach by any object from any side that is not visible from driver’s view, the whole thing will be shown up on the screen which will let driver enough time to slow down and let the object go before it passes a tight parking spot or a narrow alley-way. Cameras on the rear bumper of the vehicle also help when the vehicle is reversing with a live feed of angles which may not be seen by the driver. Reverse parking sensors generate audible beeps in different frequency to let the driver know how close the vehicle may be to an object which is behind it. Radar or ultrasonic sensors are placed on the sides of the vehicle in the rear and front bumpers. When a vehicle is detected close on the rear of the vehicle by the sensors it warns via a light signal blinking on the rear view mirror, but when the warning is ignored, and audible strong warning is played out loud to further announce the increased danger to the driver.
Most of the BSD systems only identify the moving vehicles but they do not react to objects which are fixed like lamp-post or a signal on the crossroads which the subject vehicle passes by. A bit expensive at first, but then it is a huge trouble and money saver in terms of insurance and legal litigations filed against you if any accidents happen on the road because of the BSD.
