10 - VB3i Dynamic Modes

Table of contents
No headers

The VBOX has three dynamic modes. These dynamic modes directly change the SMI smoothing index applied by the GPS engine to all Doppler-derived data, notably speed and heading. The lower smoothing levels have a higher dynamic response but are adversely noisier.

The three options are:

  • High dynamics: The ‘High dynamics’ setting should be used for high accuracy trigger brake stops or any test where time and distance are critical and the vehicle test incorporates highly dynamic manoeuvres.
  • Medium/ Normal dynamics: The 'Medium' or ‘Normal’ mode should only be used for any testing that does not involve any high dynamic manoeuvres.
  • Low dynamics: The ‘Low dynamics’ mode can be used for smoother velocity and heading data and less acceleration noise only in lower dynamic tests.
