Adaptive control

The TCM  monitors each gearshift in order to enable smooth gearshifting under all driving conditions. To do this, the control unit controls the brushless DC motors for the clutch and gearshift system via an open-loop control system.

Adaptation of the following is performed: 

• Clutch engagement points
• Clutch friction coefficient
• Individual positions of the synchronizer assembly

The adapted values are stored in the non-volatile RAM (read/write memory) of the control unit. This permits improved shifting smoothness and increases transmission service life.
