CANalyzer.Car2x - Analysis of embedded systems with ITS-G5/IEEE802.11p

Analysis Tool CANalyzer.Car2x

Functions

Option .Car2x extends CANalyzer by adding WLAN-specific functions including a WLAN channel that complies with IEEE 802.11p:

  • Configure up to 8 WLAN channels for simultaneous analysis and stimulation of control and service channels
  • Interpretation and display of protocol header information, including validity check of secured packets as well as decoding of application messages (defined in ASN.1)in the Trace Window
  • Signal analysis of application messages in Graphics and Data Window
  • Display multiple Car2x objects such as ITS Vehicle Stations or ITS Roadside Stations on map material. This includes synchronization with other windows for later analysis.
  • You can configure analysis filters for the desired ITS objects by drag & drop from the Map Window to the Trace Window.
  • Use the WLAN Packet Builder to create and interactively send WLAN packets.
  • The Car2x Station Manager is the central unit to manage ITS Stations. With the help of the Car2x Station Manager, received messages are assigned to ITS stations that are managed in CANoe. This way, CANoe.Car2x offers not only a message based view but also an ITS station based view on the communication.
  • You can use the Car2x Network Explorer to search for specific elements within the complex structure of an application message.
  • If available, the GPS time from the WLAN device is displayed with the WLAN packets and recorded
  • Replay and offline analysis of recorded measurement data

Application Areas

Option .Car2x is especially well-suited for analyzing and logging communication of ECUs in the vehicle or in the infrastructure, which communicate using IEEE 802.11p in conformance with ETSI ITS-G5 or IEEE 1609 - WAVE.

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). 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. For the analysis of recorded WLAN packets, synchronization of the Map window with the other windows is particularly useful. It allows you to quickly locate certain traffic situations and analyze the related communication.
