The mechatronic unit's electronic control unit is the central gearbox control unit. All sensor signals and all signals
from other control units come together here, and all actions are performed and monitored by it.
11 sensors are integrated into the electronic control unit; only the gearbox input speed sender G182 is located
lk
outside of the control unit. The electronic control unit hydraulically controls and regulates eight solenoid valves for
shifting the 7 gears and for actuating the clutch.
The electronic control unit learns (adapts) the positions of the clutches and the positions of the gear selectors when
a gear is engaged and takes what has been learnt into consideration for further operation of these components.
