The system uses a camera mounted near the interior mirror to read the roadsigns. It then compares them with the data already stored in the car's navigation system and relays the information to the driver.
This dual mode of operation allows Speed Limit to be accurate even if, on some roads, the speed limit has changed for one reason or another. If so, all the driver has to do is comply with the information relayed by the camera.
The data provided by the system is being displayed either in the instrument cluster or on the Head-Up Display (HUD), minimizing the risk that comes with taking the eyes off the road.
“This technology is a first for the Australian market, and typifies the approach BMW takes in respect to development of cutting-edge technology solutions,” Stavros Yallouridis, BMW Australia managing director said in a statement cited by BMWblog.
“The ultimate driving machine must offer unrivalled performance capabilities, as well as the most advanced safety systems available in the world today.”
According to BMW, the system will become available on the BMW 760Li, 750Li and 750i later this year as a standard feature. The rest of the 7 Series range, as well as the 5 Series Gran Turismo, 5 Series Sedan and 5 Series Touring will get Speed Limit technology as an option, for AU$700.
