<strong>Final</strong> Report <strong>PRE</strong>-<strong>DRIVE</strong> <strong>C2X</strong> 29.9.2010<br />
The hardware architecture in both cars is similar. The application host is a Linux<br />
system running a Knopflerfish-Framework in both cars, which are a car-pc in the<br />
Audi A6 and a laptop in the Volkswagen Scirocco. As communication device we<br />
installed a LinkBird-Router v3 from NEC is installed in both cars.<br />
To display the Use Cases we use two different systems, whereby the activation<br />
occurs via specific hardware. In the Audi we use the original MMI-display with an<br />
additional adapter. As Onboard-HMI in the Volkswagen we use a common<br />
Volkswagen navigation system (RNS 510) with some minor hardware changes to<br />
enable an easier access by <strong>PRE</strong>-<strong>DRIVE</strong> <strong>C2X</strong> applications. This interface enables<br />
the display of application output as well as the touch screen input for the control of<br />
the main unit for the Scirocco. These two units are connected via LVDS (Low<br />
Voltage Differential Signaling).<br />
The positioning occurs over uBlox GPS receivers, which are connected with the<br />
Volkswagen CarGate.<br />
It includes both, LLCF and VAPI and is connected to the vehicle buses to deliver<br />
event messages from the vehicle system to the <strong>PRE</strong>-<strong>DRIVE</strong> <strong>C2X</strong> applications.<br />
Actually it represents the "Vehicle-Gateway". It also gets the NMEA stream from the<br />
GPS receiver.<br />
The only difference between the Volkswagen and the Audi is in the format of the<br />
CAN bus messages to access in-car information, which is thanks to the VAPI easy<br />
to accommodate.<br />
A new roof antenna is suitable for UMTS, GPS, WLAN 2.4 GHz and WLAN 5.9 GHz.<br />
BMW vehicle<br />
Figure 35: <strong>PRE</strong>-<strong>DRIVE</strong> <strong>C2X</strong> demonstration vehicle of BMW base on BMW X5<br />
The BMW test vehicle follows the hardware and software architecture defined for the<br />
whole project. The differentiation from other test vehicles lies primary at the<br />
presentation of each use case. The BMW test vehicle uses both the standard in-car<br />
display and a separate programmable display in the dash area, in order to display all<br />
relevant information to the driver.<br />
