An important part of the DSG-transmission is the mechatronic. This is the electronic command centre, and engages clutches and selector forks (gears) by electro hydraulic actuators.
The mechatronic evaluates a selection of data:
- Gearbox input speed
- The speed of both driveshafts
- The wheel speed (Through ABS sensors), to calculate the road speed
- Accelerator pedal position sensor, to see if the driver wants to accelerate or decelerate.
From this data, the mechatronic recognizes whether the gearbox needs to up or downshift. And therefore, knows which gear needs to be pre-selected.
