, audible, vibrating, or tactile. Blind spot monitors may do more than monitor the sides and rear of the vehicle. They may also include "Rear Cross-Traffic Alert", "which alerts drivers backing out of a parking space when traffic is approaching from the sides."

History

If side view mirrors on a car are adjusted in a particular way, there is no blind spot on the sides. This method was first revealed by George Platzer in a 1995 paper presented to the

classes and takes some getting used to. Calculated elimination of blind spots by trained drivers is inexpensive and obviates the need for expensive technological solutions to that problem, provided drivers take the time to set up and use their mirrors properly. Platzer received a patent for his blind spot monitor, and it has been incorporated into various products associated with Ford Motor Company. The blind zone mirror has been touted as "an elegant and relatively inexpensive solution" to this recognized problem.

This system was first introduced on the 2001 Volvo SCC concept car, then placed into production on the 2003 Volvo XC90 SUV and produced a visible alert when a car entered the blind spot while a driver was switching lanes, using cameras and radar sensors mounted on the door mirror housings to check the blind spot area for an impending collision. Volvo won an AutoCar Safety and Technology award for the introduction of this feature.

was the first Japanese automaker to offer a blind spot monitor, which they refer to as "BSM" (Blind Spot Monitoring). It was initially introduced on the 2008 Mazda CX-9 Grand Touring and remained limited to only that highest trim level through the 2012 model year. For 2013, BSM was standard on both the CX-9 Touring and Grand Touring models. Mazda also added BSM to the redesigned 2009 Mazda 6. Blind spot monitoring was standard equipment on the 6i and 6s Grand Touring trim levels, and was an available option on some lower trim levels. Mazda has since expanded the availability of BSM, having added it to the feature list of the Mazda2, Mazda3, CX-3, CX-5, MX-5 Miata, and the upcoming CX-30, often as part of an option package.
