Voice control system, general 

The individual functions of the driver information system are called up and operated via the voice control system (VCS [SBS]). The VCS [SBS] is integrated into the COMAND controller unit (A40/3). The voice control system can be operated by spelling out or entering complete words.

The voice control system is activated or deactivated via the following buttons on the multifunction steering wheel (MFL):

• Voice control system ON button (S111s4)
• "Back" and voice control system OFF button (S110s4)

The voice control system button control signal is forwarded via the following components to the COMAND controller unit:

• Direct line
• Steering wheel electronics (N135)
• Steering LIN (LIN E1)
• Steering column tube module control unit (N80)
• Chassis CAN 1 (CAN E1)
• Electronic ignition lock control unit (N73)
• Chassis CAN 2 (CAN E2)
• Instrument cluster (A1)
• Interior CAN (CAN B)

The voice input takes place via the hands-free system microphone group (A67b1), which is connected to the COMAND controller unit via a direct line. The words spoken into the hands-free system microphone group are converted into an electrical signal and forwarded to the COMAND controller unit.

Voice recognition by the processor integrated into the COMAND controller unit requires the driver's voice to be taught in beforehand.

If the driver's voice or the message of the voice command cannot be uniquely identified, the VCS [SBS] issues a query. The audio signals are generated by the COMAND controller unit and output over the speaker system, in vehicles with CODE 810 (Sound system) or CODE 811 (Advanced sound system), over the Media Oriented System Transport (MOST) and the sound system amplifier control unit (N40/3).

More detailed information on the speaker system is available in the Speaker output function documentation.
