Traction Regulation
The traction target value is divided in the front and rear as a function of the support roller RPM.

RPM Regulation
The variable (control of the eddy current brake) is divided between the front and rear axle. This
happens again as a function of the support roller RPM.

Road Load Simulation
The traction target value which is calculated from the individual Road Loads, is divided between
the front and rear axle as with the normal traction regulation.
