ConfiguringTheBRAKEBOX / VariablesToShow

Variables to Show

Whilst speed, path distance and time results are always shown, there are also another six variables that are optional:

• Forward distance. This is the distance that the vehicle has travelled during the test in the direction of the initial heading.
• Deviation distance. This is the deviation laterally from a straight line in the direction of the initial heading. Note that this is the deviation at the end of the test, NOT the maximum deviation recorded. Deviation during the test may be seen using the tables. The sign convention is that deviation to the right is positive, and to the left is negative.
• Direct Distance. This is the distance directly from the start point of the test to the end point of the test.
• Average Acceleration. The sign convention used is that acceleration is positive, and deceleration is negative.
• MFDD (Mean fully-developed deceleration). This is the average deceleration recorded between 80 and 20% of the test start speed
• Initial Heading. This is the heading recorded at the start of the test.

Each of these variables can be used or hidden. If they are used then they will be displayed on the screen immediately following a braking test and included in the printed tables of results, if printing is enabled. A more detailed explanation of the various distance metrics used can be found in the “Explanation of Results” section later in the manual.
