Blind-spot monitoring (BSM) is just what its name implies: It keeps an eye on the space just off the rear quarter areas of your vehicle. These blind spots can hide a vehicle approaching in an adjacent lane because many drivers improperly set their car’s outboard mirrors. Consequently, merging into that lane often results in a crash.Get more news about blind spot sensor,you can vist our website!
In fact, according to the National Highway Traffic Safety Administration (NHTSA), roughly 9% of all reported vehicle crashes each year result from changing lanes or merging.
BSM is an active driver aid/safety device with the ability to detect what your eyes may miss, issuing a warning as a vehicle approaches in an adjoining lane.Once only found in high-end luxury cars, blind-spot monitoring eventually trickled down to even economy cars. If BSM isn’t standard on a vehicle, it’s probably available as a stand-alone option or in an option package.
The larger your vehicle, the bigger the blind spot. The bigger the blind spot, the more BSM can help prevent you from changing lanes into another vehicle.As far as today’s crop of driver-aid technologies goes, blind-spot monitoring is quite simple. The least sophisticated examples use radar or ultrasonic sensors embedded in each side of the vehicle’s rear bumper. These sensors detect a vehicle approaching the rear of your car in an adjoining lane. More sophisticated BSM systems also employ side-mounted cameras.
When BSM recognizes a vehicle about to enter a blind spot, it warns you that a particular adjoining lane is not clear. Commonly, the alert comes in the form of a yellow warning light somewhere on the outboard rearview mirror on whichever side of the oncoming car is involved. It may, instead, appear on your vehicle’s A-pillar (the pillar between the windshield and either front door), driver-information display, or head-up display.
A few brands, such as Honda and Kia, provide an audible alert in some models. Often, audible alerts will sound if you use your turn signal, indicating you will merge into an occupied lane.Blind-spot monitoring eliminates some of the guesswork from effectively positioning your outboard mirrors because it acts as an early warning system for vehicles about to pull alongside you.
It uses a combination of sensors and sometimes side-mounted cameras to track approaching traffic in adjoining lanes. You can often spot the sensors. They are usually quarter-size round indentations in the bodywork or fascias.
Once BSM senses an advancing vehicle, it springs into warning mode. Some blind-spot monitoring systems are so sophisticated that they will nudge you away from the lane marker on that side. The system may even steer you back to the center of the lane.As technology tends to do, blind-spot monitoring continues to evolve. When first introduced fewer than 20 years ago, BSM was a novelty reserved for premium and luxury cars. Today we find it on the most affordable of models. For example, it’s standard on the $19,500 Nissan Kicks S and comes with the $500 Technology Package for the $19,590 Kia Forte LXS.
As already mentioned, cutting-edge BSM versions that either nudge you away from the lane marker or steer you back to the lane’s center are also available in many cars. They accomplish this through steering or by applying brake pressure to one or more wheels.
Even full-size pickup trucks are getting into the act. No matter the brand, every full-size pickup has blind-spot monitoring either standard or available. The Ford F-150 and Ram 1500 pickup trucks take it even farther. They offer BSM that extends to the trailers they are towing.
