Gearbox management system
Gearbox input speed sender G182
The gearbox input speed sender is inserted into the
gearbox housing.
The gearbox input speed is identical to the engine
speed.
It is the only sensor located outside of the mechatronic
unit.
The sender operates according to the Hall principle.
It electronically scans the starter ring gear and
thereby records the gearbox input speed.

Signal use
Effects of signal failure
The control unit requires the gearbox input speed
signal to control the clutches and to calculate slip.
To do this, it compares the signals from the gearbox
input speed sender G182 before the clutches with the
signals from senders G612 and G632, which transmit
speed signals from the drive shafts.
In the event of signal failure, the control unit uses
the engine speed signal as a substitute signal.
It obtains this signal from the engine control unit
via the CAN bus.
