Mechatronics - electronics and mechanics in one unit.
Intelligent shifting in all conditions
The clutches and gearbox units in the DSG are operated hydraulically. This function is performed by the gearbox mechatronics module, housed in the DSG. The term “mechatronics” is derived from combining the words “mechanics” and “electronics”. And this is exactly how the mechatronics module is structured with the electronic transmission control unit, various sensors and the hydraulic control unit all forming one compact entity.
The control unit uses information such as engine speed, driving speed, accelerator position and driving mode to select the optimum gear and to determine the ideal shift point. The hydraulic control unit then implements the shift commands in a complex sequence of individual, precisely coordinated actions.
The mechatronics module can perform complex shift operations in a fraction of a second. It consists of a control unit and a control valve assembly together with individual sensors and actuators. The gearbox’s control unit is in constant communication with the engine control unit. This “dialogue” determines the ideal point at which to make a gear change, which means the engine is always only consuming as much fuel as it needs to at that point.
