Blind spot monitor

[3] Platzer received a patent for his blind spot monitor, and it has been incorporated into various products associated with Ford Motor Company.

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.

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.

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.

While only a concept car, the Ford GT90 was the first vehicle to be fitted with a modern blind spot monitoring system.
