BMW X3 Owners Manual: The concept
Speed limit detection Speed limit detection uses a symbol in the shape of a traffic sign to display the currently detected speed limit. The camera in the area of the interior rearview mirror detects traffic signs at the edge of the road as well as variable overhead sign posts. Traffic signs with extra symbols for wet road conditions, etc. are also detected and compared with the vehicle's onboard data, such as for the rain sensor, and will be displayed depending on the situation.
The system takes into account the information stored in the navigation system and also displays speed limits present on routes without signs.
Hints
Personal judgment
The system cannot serve as a substitute for the driver's personal judgment of the traffic situation.
The system assists the driver and does not replace the human eye.
