9.5 Load Adaption (Optional)
Use this menu point to do various adaptions; e.g. dyno coefficients can be determined here. The
iterative coefficient adaption can be done based on the following standards, whereby the
vehicle must be defined in the vehicle database before doing the adaption.
→ After the menu point LOAD ADAPTION the following function selection appears:
ECE / SAE J2264
9.5.1 Coefficient Adaption based on ECE
1 Position the vehicle on the dyno and fix it.
2 Call up the menu LOAD ADAPTION and then
the menu item ECE.
→ The following screen appears:
3 Enter the parameter in the boxes using the
digit keys or, if available, load these from
the database with the <F6 DATABASE> key.
4 Use the button<F8 CONTINUE>.
→ The measurement screen appears.
Use the cursor keys <

> and <

> to change between the values. Delete erroneously entered
characters using the <BACKSPACE> key. Delete a complete box with the <DELETE> key.
5 Accelerate the vehicle up to 110 km/h.
6 Once the displayed target speed is reached,
the roll out trial is initiated (release gas and
disengage clutch).
The dyno is braked based on the preset
simulation model. The actual time (ECE) is
measured and displayed at each interval.
7 Repeat steps 5 and 6 until all intervals are in the green range.
With the iterative coefficient adaption based on ECE Standard the evaluation is done per
interval. Referring to the target time, the time error is calculated and issued. If the time error is
within the tolerance range, the line is showed in green. If the time error is outside of the
tolerance range, the line is shown in red. The dyno repeats the coefficient adaption
automatically until all set intervals are within the green range and/or the max. set number of
runs (standard is 6) are done.
