Analysis of 802.11p-based Communication Applications

CANalyzer.Car2x

Option Car2x is especially suitable for analysis of ECUs which exchange information with other vehicles or the traffic infrastructure based on V2X application messages. Domain-specific measurement windows enable the effective analysis of communication across all protocol levels.

CANalyzer.Car2x is designed to meet your requirements in an optimum way. You get a fully developed tool which is adapted to the requirements of the V2X domains from the ground up. CANalyzer.Car2x supports standards and protocols from the regions of China, the EU and the US released by GB/T (China), ETSI (EU) and IEEE (US). This includes application messages such as CAM, DENM, SPaT, MAP, BSM, IVIM, SREM and SSEM, as well as subordinate protocols such as DSMP in China, GeoNetworking in the EU and IEEE 1609 (WAVE) in the US. For the wireless standard, you can choose whether communication is to occur over WLAN IEEE 802.11p or 3GPP C-V2X PC5, where there are hardware solutions for both versions.

In addition, all the powerful functions you’re familiar with from CANalyzer are available. This makes CANalyzer with the Option Car2x the ideal expansion of your multibus analysis tool for getting your V2X-based ECUs on the path to readiness for serial production. 

Advantages

  • CANalyzer.Car2x supports the wireless standards WLAN IEEE 802.11p and 3GPP C-V2X PC5.
  • Protocols and application messages of the China, Europe and US regions are supported.
  • The management of ASN.1-based application messages in a flexible database ensures supplementation with additional application messages by the user.
  • Domain-specific measurement windows for V2X, such as the Map Window, enable efficient analysis of communication.
  • Synchronization of the Map Window with other measurement windows simplifies subsequent analysis.
  • Security mechanisms are supported for all regions (China, EU and US), including importing and management of a PKI with its certificates and private keys.

Application Areas

  • Analyze the V2X-specific communication protocols in the Trace Window, access application messages described in a database (CAM, DENM, BSM...) and configure your individual measurement desktop.
  • Log the communication of ECUs in the vehicle or the infrastructure that communicate via IEEE 802.11p according to ETSI ITS-G5 or IEEE 1609 – WAVE or 3GPP C-V2X PC5.
  • Manage certificates required for validation of signed packages.
  • Visualize the position and direction of several objects as well as occurring events on a road map in the map window. In addition, synchronization with other windows enables subsequent analysis. 
  • Access data from different networks. Complete the toolchain seamlessly with Option Car2x and check gateway functionalities. 
  • Configuration of several 802.11p WLAN channels for simultaneous analysis of control and service channels. The new 802.11p measurement interface VN4610 is fully integrated and features intuitive configuration options.

Functions

Application messages

With CANalyzer.Car2x, you can use any application messages, like CAM/DENM (ETSI) and BSM (C-SAE and SAE), which are defined in ASN.1.

 

Car2x Network Explorer

Network Explorer

The Car2x Network Explorer is a viewer for Car2x databases. It offers a clear depiction of the data structure of the messages and makes it possible to quickly locate the signals being searched for.

Car2x Database

Simulation Setup

To decode and interpret V2X messages, CANalyzer.Car2x requires a description of the application message. These messages are made available to CANalyzer by the Car2x databases and contain all the information necessary for decoding and converting the raw values into physical values.

Analysis

Map Window

Map Window

The Map Window provides you with a quick overview of your traffic scenario. Here, the locations of all received V2X objects (ITS vehicle stations, ITS roadside stations) and the received events are also visualized automatically on the map.

Window synchronization also makes it possible to – when measurement is stopped – go through the messages step by step and analyze the data in the Map Window with the data of other measurement windows, such as the Trace Window.

Protocol Analyzer

Protocol Analyzer

Using the Protocol Analyzer, you execute V2X protocol checks automatically. You can check protocol-specific content individually for various protocols, such as DSMP, GeoNetworking, IEEE 1609.3 and security (China/ETSI/IEEE 1609.2). If an error is detected, warning and error messages are displayed in the Trace Window and in the detailed view.

Trace Window

Trace Window

The Trace Window provides extended functionality for evaluating V2X packets, protocols (GB/T DSMP, ETSI and WAVE 1609.x) and the application messages (C-SAE, ETSI and SAE).

In addition to the general functions in CANalyzer, you can adapt the window in a domain-specific way, where application messages are decoded according to the definition in the database. You can configure columns, highlight packets/protocols/ITS stations in color or analyze error messages of the Protocol Analyzer. In addition, messages from a sender can be displayed on a line, which increases clarity considerably.

Data Window/Graphic Window/State Tracker

Select signals from vehicles which you would like to monitor. The Data Window displays the resolved values, including the units defined in the database. If you would like to display these signals graphically, the Graphics Window can be used as an alternative.

Car2x Station Manager

Station Manager

The Car2x Station Manager is the main unit for managing ITS stations. Using the Car2x Station Manager, you can assign received packets to the ITS stations managed in CANalyzer manually or automatically.

This means that CANalyzer.Car2x not only offers a packet-based view of communication, but an ITS station-based view as well. You can define individual colors for ITS stations for a clear overview.

VN4610

VN4610 Network Interface with GNSS receiver

The VN4610 is a powerful interface with a host connection over USB or Ethernet for accessing IEEE 802.11p and CAN(FD) networks. IEEE 802.11p-based Dedicated Short Range Communication (DSRC) communicates in the 5.9 GHz range.

The VN4610 supports the unfiltered reception and sending of IEEE 802.11p frames used to implement V2X applications. The received IEEE 802.11p wireless frames are transferred to the application time-synchronized with the CAN(FD) messages.

The built-in GNSS receiver provides the GNSS time and the current GNSS position here.
