Function sequence for navigation mode
The data for reaching the destination (destination-oriented navigation) is calculated via the navigation system integrated into the radio with auto pilot system (A2/56) from the data entered.
To this end, the navigation system is equipped with the following functions, which are described in separate documents:
^ Position finding and destination-oriented navigation, function
^ Route guidance through voice output, function
The route is calculated in accordance with the options set. If it should not be possible to adhere to the options, then the configured options are ignored for the stretch in question and a corresponding message is output visually as well as acoustically.
The set criteria and options can be displayed and changed at any time. After a successful route calculation, the route is displayed by arrow pictograms and there is an acoustic message output stating "the route is calculated". If the vehicle is no longer moving on the precalculated route, the route is recalculated.
If the recalculated values are plausible for the navigation system, then the modified route is displayed.
Dynamic route guidance
The dynamic route guidance considers the current traffic situation.
The control signals of the left multifunction steering wheel button group (S110) and right multifunction steering wheel button group (S111) are provided via the following route:
- Steering wheel electronics (N135)
- Steering LIN (LIN E1)
- Steering column module control unit (N80)
- Chassis CAN (CAN E)
- Instrument cluster
- Interior CAN (CAN B)
- Radio with auto pilot system
If entered via the Audio/COMAND control panel (A40/9), the control signals are read in via telematics CAN (CAN A) by the radio with auto pilot system.
If the signals are entered directly using the control buttons on the radio with auto pilot system, the control signals are processed within the radio with auto pilot system.
Voice input (with code (511) Audio 50 APS incl. DVD changer) is conducted using the hands-free system microphone (A67b1). The spoken word is converted into an electrical signal via the hands- free system microphone and forwarded to the radio with auto pilot system via a direct line.
For the voice control (in particular entering a destination) of the navigation (with code (511) Audio 50 APS with DVD changer) lists of names are also provided in the system.
The following lists are available for the voice control system:
- List of place names for selected towns on the data storage device
- Street name list for all towns/villages
- List of the relevant intersecting street
- Town center list
