The Telematics services are part of the Online Car project. Technical requirements for the use of the Telematics services are:
The basis of the Telematics scope of functions in the E65 is identical to that in the E38. The following functions have been added
The navigation computer is located in the trunk on the left-hand side under a flap; it is cooled by an integral fan. If there is insufficient cooling, excess temperature leads to deactivation. The deactivation is indicated with a signal on the Control Display.
The control module is connected to the MOST bus. In the MOST framework, the navigation computer also performs controller functions.
The telephone module (transmit-receive unit) is connected to the MOST network so as to integrate the telephone in the communications network.
The video module contains a TV receiver and the switchover facility for the video, audio and RGB signals. The video module controls the control display via RGB lines. After ”ignition ON”, the video module automatically recognizes whether a navigation system is a component part of the overall system and responds accordingly. The video module is a self-diagnostic control module in the MOST network. The video-module outputs are monitored by fault memories.
The RGB lines (red/green/blue lines) serve to transmit the image signals from the video module to the Control Display.
The CVBS (Composite Video Burst Sync) signals are bus signals that contain all the image information.
Control Display Apart from a few exceptions, the Control Display incorporates the controls and displays for the vehicle electronics. The Control Display coordinates the function requests from the system and assigns them to the relevant functions.
The functions of the Telematics services navigation are operated from the Control Display.
If the special equipment 'voice input system' and 'telephone' are fitted, it can be operated by voice input.
Controller: The Control Display is operated by means of the Controller located at the front in the center armrest.
The instrument cluster can also display navigation system information in conjunction with the Control Display.
The K-CAN SYSTEM data bus is the data connection between the instrument cluster and the control modules in the chassis and suspension, drive and body sections. Information is exchanged with data telegrams.
The MOST (Media Oriented Systems Transport) bus links the audio, video and navigation systems. Information relating to function requests is transmitted to the relevant control modules by means of MOST bus messages.
In order to display the different functions and information, the shield is divided into three independent windows.
Button bar: The usable functions are displayed on the button bar (left):
The arrow symbols are used for browsing.
After selection of, e.g., V Info Plus, the traffic information announcements are sent by the provider.
After selection of a message, up to two additional information pages can be displayed by browsing with the arrow.
RGB shield: If, for example, a driving route is displayed on the RGB shield (center), the following supplementary information can be shown on the supplementary information pages:
One supplementary information page covers the left and center shield section.
Assistance window: Information from other applications is displayed in the Assistance window (right), e.g. navigation roadmap.
After selection of the BMW menu item, the BMW ASSIST menu is displayed. When BMW Service is selected, the available services are displayed. At the same time, contact to BMW Service is displayed in the Assistance window (right).
Emergency service: When this service is started, unchanged key data and, if possible, the position of the vehicle are transferred. The function is now no longer linked to the GPS data.
Home dealer: When this service is started, the key data is read out of the CAS, Car Access System. The data is transferred to the telephone and converted there into a key data SMS (Short Message Service). The SMS is transferred to the service provider. The service provider sends the information as an e-mail (electronic mail) to the home dealer.
At the same time, the service provider sends an SMS back to the customer. This contains the confirmation and the telephone number of the home dealer. A call is then placed to this telephone number (similar to, e.g., directory information service). If the home dealer does not take the call, the dealer can call the customer back after reading the e-mail.
Nearest dealer: This menu item is omitted if no navigation system is fitted. If there is a navigation system, this function is not a Telematics function because there is no data transmission between the vehicle and service provider. The nearest BMW dealer is only transferred from the navigation CD to the Control Display as a navigation destination with telephone number and displayed there.
Hotline: If this service is started, a call is placed to a programed telephone number.
The automatic configuration update is repeated three times at intervals of two minutes. In the case of roaming (network change), the services configuration runs automatically. The automatic run is necessary because the different providers offer different services.
Make the initial entry of the home dealer on handover inspection using the DISplus. If the data is changed due to vehicle sale or for other reasons, an update can be performed (also by the user) in the BMW portal (my BMW).
