This paper treats about “Line Traction 3” (LT3), which is a mechatronic driveline for heavy
machinery like agricultural tractors, combines, or wheel loaders. LT3 is expected to improve
the performance and augment new functions to the existing ones of conventional drivelines.
For testing and validating this assumption for LT3 and similar driveline systems, we introduce
“MOBiL” , a hardware-in-the-loop method adapted for mobile machinery. The MOBiL method
will be explained to bring out the differences in modelling and test procedures compared to
on-road hardware-in-the-loop methods. Then, we will present the validation of the LT3
driveline in an agricultural context by using the MOBiL method. A discussion of the relevant
results obtained for tractors and wheel loaders will be followed by a final summary.
