Abstract: A method for controlling a gear unit of a motor vehicle having synchronizing devices. When an actuating device of a synchronizing device is controlled in terms of force or travel, strongly differing wear behavior occurs depending on use. The inclination of the travel path or the shifting frequency is detected during operation of the motor vehicle and a characteristic diagram is used in order to adapt the shifting force to the information item obtained.

Abstract: An arrangement with a torque-controlled gearbox, for which the torque present on the transmission driving shaft is measured with a non-contacting torque sensor and the torque sensor supplies a measuring signal, which is fed to the gear control unit as a variable for the correct shifting moment. With a motor vehicle having an internal combustion engine, the drive output of the combustion engine is transmitted to the crankshaft, and the torque present at the crankshaft is transmitted via a clutch and an intermediate gear to the transmission drive shaft, from there to an output drive shaft, and finally via a differential gear to the drive wheels of the motor vehicle. The torque sensor detects the torque actually present at the transmission drive shaft and feeds the measuring signal proportional to this torque to a gear control unit. The arrangement advantageously permits a torque-free shifting of gears in the gearbox, which can thus be carried out comfortably.
