Universal Gateway

Routing between different Automotive Bus Systems in Real-Time

The number of electronic devices in vehicles integrated in different bus systems is rising constantly. To assure a flexible and reliable complete system for a comfortable driving experience information must be routed between the respective field buses in real-time. This challenge is easily met by integrating the K2L Universal Gateway (UGW) library in your product. UGW is scalable in number and type of connected buses while it is fully configured in a tool driven way without any recompilation of source code.

The K2L Universal Gateway (UGW) routes information between automotive devices connected to different field buses in real-time, converts different signals and units and handles buses with different speeds.
UGW realizes an abstraction of the different physical layers as well as an abstraction of different protocols.
Due to the flexible software design all automotive buses like CAN, MOST®, LIN and FlexRay™ can be added easily. Also an internal application bus has been integrated to allow 3rd party application to send and receive messages on the buses via UGW (a native connection to the very field bus driver is also possible).
For applications like flashing or diagnostics a high bandwidth access to the UGW and the connected automotive buses can be realized by an application connected to Ethernet.
UGW includes a bus independent gateway core to perform the message and signal conversions. The set of available routing and conversion rules can be adjusted according to the OEM specific project requirements.
The K2L-Composer tool enables creating and processing a gateway table to export the gateway configuration as binary data file and as C-header-file containing the configuration as C-structure. Furthermore many OEM specific gateway table formats, from formatted text files to several flavors of Excel tables up to XML based formats like FIBEX are supported as input.
