BMW 7 Series: Introduction
History
Voice-activated control was offered for the first time as an option for the E38. The system enabled the driver to operate the telephone and the navigation system without taking his or her eyes off the road and the traffic situation.
As the voice recognition system evolved, the number of spoken command the system could recognize increased by leaps and bounds from the initial 30 to the current figure of about 470 (CCC with the "Voice Activation" option in the E60, E90). This means that in the current models, voice control can be used not only for the telephone and the navigation system, but also for entertainment, the address book, the air-conditioning functions and vehicle individualization settings.
Voice Activation is standard equipment on the F01/F02 and it is always combined with the "Navigation System".
NOTE: The Voice Activation System and the "Navigation System" are both standard on the F01/F02.
The Voice Activation system has been further enhanced.
There is now an even larger range of spoken commands and for the first time the user has the option of individualizing the voice recognition system in accordance with specific needs and preferences. For example, users can match the voice recognition system to their own knowledge base and use the controller to change the spoken-language setting.
Other innovations of the voice activation system include:
- Visual feedback in the instrument panel.
- No audible beep signal during a dialog with the system.
- Combined mode with both voice inputs and controller inputs.
- Intersections and zip codes can be entered as destinations.
- Voice control of contacts, phone book and address book with up to 3000 entries.

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.
