•
The AWD CM calculates the optimal amount of torque distribution for the rear wheels and outputs a
corresponding electric current to the electronic control coupling (AWD solenoid). This calculation is based on
the accelerator pedal angle, four-wheel speed, engine speed, and other related input signals, matched with the
vehicle driving and road surface conditions.
