Publication number: 20230046052Abstract: 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.Type: ApplicationFiled: August 1, 2022Publication date: February 16, 2023Applicant: ZF Friedrichshafen AGInventors: Christoph Hess, Jörg Arnold, Jens Weller

Patent number: 9574585Abstract: A method is provided for the operation of an assembly of a vehicle, whereas the assembly is transferable from an unactuated position into an actuated position by a pressure medium-actuated actuator if two redundant pressure medium valves both occupy a pressure supply position. For the functional test of one of the valves, a first valve is controlled to occupy the pressure supply position, and the second valve is controlled so as not to occupy the pressure supply position. If, upon this control of the two valves at the pressure medium-actuated actuator or at the assembly to be operated by the pressure medium-actuated actuator, no reaction is detected, there is a correct operation at a proper second valve. If, despite this control of the two valves, at the pressure medium-actuated actuator or at the assembly to be operated by the pressure medium-actuated actuator, a reaction is detected, there is an improper operation at a defective second pressure medium valve.Type: GrantFiled: August 12, 2014Date of Patent: February 21, 2017Assignee: ZF Friedrichshafen AGInventors: Jörg Arnold, Thilo Schmidt, Klaus Steinhauser

Patent number: 9354140Abstract: A method of determining a fill current value of a converter lock-up clutch of an automatic transmission. The automatic transmission comprises a hydrodynamic converter, at which a speed ratio arises, and an output shaft. In a control sequence with the output shaft being stationary, the speed ratio is influenced by changing the control current, and the fill current value is determined from the progression of the speed ratio arising, during the control sequence, in conjunction with the progression of the control current.Type: GrantFiled: April 5, 2012Date of Patent: May 31, 2016Assignee: ZF Friedrichshafen AGInventors: Jörg Arnold, Thilo Schmidt, Valentine Herbeth, Klaus Steinhauser

Patent number: 9169925Abstract: A method for terminating a gearshift for an automatic transmission for a motor vehicle is provided, wherein a positive-locking shifting element is involved. After the initiation of the gearshift, there is an evaluation of the continuous signals of at least one control unit of the vehicle, which affect the engine torque and thus the turbine speed gradient. Based on the evaluation of the signals, an upcoming change to the turbine speed gradient that exceeds a first predetermined threshold value or falls short of a second predetermined threshold value is detected, and, upon such detection, the gearshift is terminated.Type: GrantFiled: August 21, 2014Date of Patent: October 27, 2015Assignee: ZF Friedrichshafen AGInventors: Jörg Arnold, Andreas Schmidt, Johannes Brockmann
