Functional networking
WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2017 BMW X3, 2016 BMW X3, 2015 BMW X3, 2014 BMW X3, and 2013 BMW X3. However, it is still accessible from the selected car via links, so may be relevant.
A complex system network with distributed functions in other control units is necessary for implementation of the lane departure warning as well as the high-beam assistant.
The following graphic shows the system network of the lane departure warning and the high-beam assistant using the example of the F2x, F3x, F15.
