BMW 7 Series: Introduction
F01/F02 Available with Automatic Soft Close Function
The Automatic Soft Close function (SCA) is available and can be ordered as of volume production launch.
The Automatic Soft Close function requires the installation of suitable door locks with drives for Automatic Soft Close (SCA drives).
The particular feature of this Automatic Soft Close function is that the door lock and the Automatic Soft Close drive unit are no longer a single unit. The Automatic Soft Close drive unit is separate and controls the door lock by way of a cable.
This means that the lock and the drive can be fitted separately and the installation space available can be used to the best effect.
The Automatic Soft Close option is only available for all doors on the vehicle.
The benefit of the Automatic Soft Close function is that the doors only have to be pushed or pulled lightly into the lock. This action starts the Automatic Soft Close function which closes the doors fully.
NOTE: The Automatic Soft Close function for the trunk is standard equipment and thus is not part of this option.

Operating Principle Of Optical Steering Angle Detection
Steering angle detection
The code disc enables a 4-digit digital code to be generated for each light
field. The 12- digit digital code is
formed by lining up the 4-digit digital codes. The steering-angle speed can be
ascertained from the changes to
the individual digital codes.
