VBOX Touch - Accel Mode

The Acceleration Mode allows you to perform acceleration tests using pre-defined configurations, or using your own specified values. It is also possible to display up to 4 concurrent test results on the screen. It is accessed by pressing the Mode Button Mode.png at the bottom of the screen and selecting Accel.

The last selected Acceleration test will be displayed after each power cycle. It is possible to choose from either Speed or Distance parameters to start and end the test. Test results displayed on the screen of the VBOX Touch will remain on screen at the end of the test until the next start condition is met.

Speed units used are dependent on what is selected within the General Settings area.


Note: If the start condition is 0 km/h, VBOX Touch will use the Smoothed Speed Value to reset the test to avoid a test incorrectly resetting within noisy satellite reception areas.

Accel Mode Overview

There are 3 different Acceleration screens which can be accessed by selecting the Forward Forward Arrow.png and Back Backwards arrow.png arrows on the bottom right of the screen or by swiping the screen left or right.

Accel - Primary Screen

This is the default acceleration screen and displays current/completed test information. If One Foot Rollout or Slope Correction is enabled within the Accel Settings, the test header text will reflect the options.

The screen is split in two halves:

  • Left hand side: This includes a live speed display which will always show the current speed of the vehicle, irrespective of any test start or end conditions. If the vehicle is traveling less than 0.5 km/h or satellite lock is lost (less than 4 sats), the value will display as 000.0.
  • Right hand side: This contains test information: time taken, run number, distance travelled, maximum speed achieved (Vmax), maximum acceleration achieved (g) and height difference. These values will start to populate once the start condition of the test is met. When the end condition is met, they will remain on screen until the start condition is met again. A test can be reset by pressing the Reset button at the bottom of the screen.

Accel - Secondary Screen

This screen displays current test information for all ranges. If One Foot Rollout or Slope Correction is enabled within the Accel Settings, the test header text will reflect the options.

The screen is split in two halves:

  • Left hand side: This includes a live speed display which will always show the current speed of the vehicle, irrespective of any test start or end conditions. If the vehicle is traveling less than 0.5 km/h or satellite lock is lost (less than 4 sats), the value will display as 000.0. Maximum acceleration achieved (Peak G) and maximum speed achieved (Vmax) information is also available. These values will start to populate once the start condition of the Primary test is met. When the end condition is met, they will remain on screen until the start condition is met again. A test can be reset by pressing the Reset button at the bottom of the screen.
  • Right hand side: This contains results from the defined acceleration test ranges, either as time, distance or speed. These values will start to populate once the start condition of the test is met. When the end condition is met, they will remain on screen until the start condition is met again. Along with pressing the Settings button, Accel tests can also be defined by double tapping on an existing test range header or result.

    A test can be reset by pressing the Reset button at the bottom of the screen.
