Logging Vehicle CAN Data with Video VBOX

flag-de.png

If your vehicle is not listed in our CAN Database as a supported vehicle, we may be able to determine relevant signals from a log. Listed below are instructions on how to log CAN data from your vehicle using a Video VBOX.

Note: For safety, this procedure should not be carried out on public roads.

Depending on the electrical architecture of the vehicle, CAN may be available via the OBD connector, or a direct connection into the CAN bus wiring may be required. In the first instance, create a log of being connected via an OBD connection unless it is known that CAN information is not available via OBD on your vehicle.

The following steps assume basic knowledge of the Video VBOX products, please consult the support pages for further information. It is most helpful if we have both audio and visual representatives of these steps. This enables us to work through the CAN data. Ideally, a passenger should read aloud each instruction before the driver carries it out.
 

  1. Contact Racelogic Support to obtain a specific CAN logging scene file.
  2. Copy the file on the root directory of the logging media.
    Note: This will overwrite the existing scene on your Video VBOX so ensure you back this up before carrying out the following steps and restore the scene after creating the log.
  3. Power up the Video VBOX unit with cameras connected.
  4. Load the media into the Video VBOX unit when it is powered on, the scene will be automatically loaded onto the units internal memory and deleted from the media.
    • If you are using a Video VBOX Lite or Waterproof, the STATUS LED will flash to show the scene is loading, and the unit will beep when the load is complete. 
    • If you are using a Video VBOX Pro, the MEMORY LED's will count up indicating loading progress.
  5. Place the cameras so that they are recording areas of interest that you require can signals for, e.g. the steering wheel, pedals, gear stick, rev counter.

  1. Press the record button to begin recording - the 'REC' led should turn BLUE or GREEN depending the model.
  2. Carry out a test drive, slowly and steadily varying the signals of interest, suggested actions include:
  • Turn the steering wheel from lock to lock
  • Fully depress each pedal in turn (throttle, brake, clutch)
  • Slowly raise the RPM
  • Cycle through all gears
  • Accelerate to the safest speed possible and hold that speed for as long as possible before decelerating slowly
  • Drive in a figure of eight to help identify individual wheel speeds
  • Turn any switches of interest on and off several times, e.g. lights, traction control
  1. When the test drive is complete, press the record button again to end recording.
  2. Once the 'REC' LED is off, Remove the media and insert it into a PC.
  3. Three new files will have been created within the media folder, save these files to the PC.
  4. Send these files to Racelogic by visiting our WeTransfer page and uploading your files. Ensure you detail the exact make, model and year of your vehicle, how you were connected to the vehicle and what signals you are interested in, an example of the detail that must be included is shown below:

    Vehicle – BMW 5 Series 2009, connected via OBD Connection
  • I turned the ignition ON – the engine remained OFF.
  • I pressed on the throttle pedal, so that it reached 100 % travel and held for 10 seconds.
  • I pressed on the throttle pedal, so that it reached 50 % travel and held for 10 seconds.
  • I turned the steering wheel to full Left-hand lock and held for 5 seconds.
  • I turned the steering wheel to full Right-hand lock and held for 5 seconds.
  • I pressed on the brake pedal so that it went as close down to 100 % travel as possible and held for 10 seconds.
  • I started the engine and allowed it to idle for around 30 seconds.
  • I held the vehicle engine speed at 2000 RPM for 15 seconds.
  • I held the vehicle engine speed at 4000 RPM for 15 seconds.
  • I went for a short drive using all gears incrementing in the correct order (missing no gears).
    Note: High speed/revs is not required.
  • I finished the drive making sure I dropped down all gears, again without missing any.
  • I stopped and allowed the vehicle to idle for another 15 seconds.
  1. A Support representative will contact you about your log.

Note: Ensure you restore your existing scene into your Video VBOX after creating the log.
