Network Analysis Tool CANalyzer.Car2x

Functions

Option .Car2x extends CANalyzer 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 adapters are supported.
• Use a WLAN 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.

Application Areas

Option .Car2x is especially well-suited for analyzing and logging communication of ECUs in the vehicle or in the infrastructure, which communicate over the WLAN channel. In this process, CANalyzer.Car2x acquires both its surroundings with other vehicles (ITS Vehicle Station) or the infrastructure (ITS Roadside Station) and its own on-board networks such as CAN, LIN, FlexRay, Ethernet etc. (this requires the use of other bus-specific CANalyzer options). To receive via WLAN, CANalyzer.Car2x uses a dedicated WLAN adapter exclusively, or else it uses a WLAN adapter already installed in the vehicle, sharing it with other applications.

It is especially advantageous if a test platform is already equipped with a WLAN 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 WLAN 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.
