Transmission Mechanism

A transmission mechanism for a transmission, the transmission mechanism comprising:

• a transmission shaft;
• a further transmission shaft;
• at least two gearwheels that can be brought into form-fitting engagement with one another, one of the gearwheels designed as a movable gear and, in a disengaged position, arranged in a freely rotatable manner on the transmission shaft, the other one of the gearwheels designed as a fixed gear and arranged non-rotatably on the further transmission shaft, the movable gear connectable non-rotatably to the transmission shaft by a clutch unit and at least one transmission gear can be engaged if a clutch toothing of the clutch unit engages in a form-fitting manner in a toothing of the movable gear in a tooth-on-tooth-gap position;
• a sensor device detecting a rotational speed signal incoming into the transmission shaft and a rotational speed signal outgoing from the other transmission shaft;
• a control unit coupled to the sensor device, the control unit:
• determining and storing a time stamp for each detected edge in the respective rotational speed signal,
• after an initial engagement of the at least one transmission gear, determining an angular position of the toothing of the movable gear relative to the transmission shaft, and assigning the angular position to the time stamp, and
• determining an absolute angular relationship between the toothing of the movable gear and the clutch toothing based on the time stamp and the angular position assigned to the time stamp.
