Development & Test Tool CANoe.Car2x

Functions

Option .Car2x extends CANoe by adding WLAN-specific functions as well as a WLAN channel per IEEE 802.11p:

• Configure up to 8 WLAN channels for simultaneous analysis and stimulation of control and service channels. Up to 8 WLAN radio adapters are supported.
• Use a WLAN radio adapter in parallel as a communication module in the test vehicle and for analyzing the data traffic
• Display of protocol header information incl. decoding of ASN.1-based data descriptions in the Trace Window
• Display multiple Car2x objects such as ITS Vehicle Stations or ITS Roadside Stations on map media, e.g. Google Maps or Microsoft MapPoint
• Use the WLAN Packet Builder to create and interactively send WLAN packets.
• Nodelayer.DLL for access to WLAN packets incl. encoding and decoding of ASN.1-based data descriptions

Application Areas

Option Car2x is especially well suited for developing ECU applications inside the vehicle which communicate over the WLAN channel. CANoe.Car2x simulates the environment with other vehicles (ITS Vehicle Station) or the infrastructure (ITS Roadside Station) as well as its own on-board networks such as CAN, LIN, FlexRay, Ethernet, etc. (this requires the use of other bus-specific CANoe options).

For analysis, CANoe.Car2x exclusively utilizes a dedicated radio adapter or a radio adapter already installed in the vehicle together with other applications. It is especially advantageous if a test platform is already equipped with a radio adapter, eliminating the need to install additional wiring for a voltage supply and an antenna.

It is easy to evaluate the communication by interpreting data packets and displaying packet properties such as the radio channel and reception strength. It is possible to log the WLAN packets for later analysis, for documentation purposes or for replaying the packets to stimulate ECUs.

The Test Feature Set can be used to conduct extensive automated tests. For example, it lets you test for interoperability very quickly. In addition, complex scenarios can be created, analyzed, and if necessary reproduced in the same or modified form.
