摘要： The invention relates to the actuation of a converter lock-up clutch (44) of a hydrodynamic torque converter (4) in a vehicle drive-train by means of a safety function where, in addition to a driving strategy function, the safety function can actuate the converter lock-up clutch (44) by issuing a clutch actuation command. For this purpose, at least one rotation speed at the torque converter (4) is monitored. If the monitored rotation speed is below a rotation speed threshold, the safety function commands an actuation of the converter lock-up clutch (44) in its opening direction.

摘要： A method for calibrating an actuation of a converter lock-up clutch of a hydrodynamic torque converter having a pump wheel and a turbine wheel connected to a power-split transmission. The transmission has at least two clutches each connected to a respective power-split shaft assembly and each configured be actuated separately to close and open in order to apply a clutch torque to the turbine wheel so that a rotation speed difference between the pump wheel and the turbine wheel changes. The method includes opening the converter lock-up clutch and the at least two clutches each connected to a respective power-split shaft assembly of the transmission, rotating the pump wheel with a specified rotation speed, and applying a clutch torque to the turbine wheel as a function of an actual rotation speed difference. Clutches connected to a different respective power-split shaft assembly of the transmission are actuated in the closing direction.

摘要： A differential lock is configured for locking compensation movements between drive output shafts (4) in a differential gearbox of a vehicle. In the locking condition, at least one of the drive output shafts (4) is connected with interlock to a differential cage (2) connected to a drive input, by means of a sliding sleeve (5) which is connected rotationally fixed to the drive output shaft (4) and can be displaced axially. For axial movement of the sliding sleeve (5), which is prestressed against at least one spring element (7), the action of a pressure (6) is provided. The spring element (7) is arranged, at least partially, radially inside the sliding sleeve (5). In addition a differential gearbox with the differential lock is proposed.

摘要： A method for preventing an unintentional start of a work-performing machine, wherein the work-performing machine includes an electric machine for propelling the work-performing machine, the method including checking whether there is a driving request from a driver of the work-performing machine and detecting information relating to an operating mode of the electric machine. The method further includes determining, based on the checking in relation to the driving request and the detected operating mode of the electric machine, whether the electric machine is in a safety-critical state and, if it is determined that the electric machine is in the safety-critical state, sending a signal to the electric machine to transition the electric machine to a state not suitable for propulsion.
