Patent number: 10626968Abstract: A motor vehicle drivetrain features an input shaft, an output shaft, a continuously variable transmission for coupling the input shaft to the output shaft with a variable transmission ratio between the input shaft and the output shaft, and a bypass transmission with at least one bypass gearing, which has a fixed transmission ratio, in order to couple the input shaft to the output shaft. A value of a transmission ratio of the bypass gearing is less than or equal to half the sum of a value of the maximum forward motion and a value of the minimum forward motion of the variable transmission ratio between the input shaft and the output shaft driven of the continuously variable transmission and/or less than or equal to 1.0. The bypass transmission is configured for driving the motor vehicle with a driving speed of at least 50 km/h or 31 mph.Type: GrantFiled: February 27, 2017Date of Patent: April 21, 2020Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Julian Heinz, Martin Gentile, Matthias Urban, Markus Steckhan

Patent number: 10619724Abstract: A method of adjusting deceleration dependent shift points to maintain a target minimum turbine speed includes calculating a vehicle speed offset based on vehicle acceleration rate a predicted downshift delay for the target minimum turbine speed and converting the target minimum turbine speed to a target vehicle speed based on the deceleration condition. Thereafter, the method continues with determining a target gear based on the vehicle speed offset and the target vehicle speed, and downshifting to the target gear having vehicle speed less than or equal to a vehicle speed corresponding to the current turbine speed. The method ends with maintaining the target gear until a shift delay period is greater than a predetermined delay threshold.Type: GrantFiled: August 2, 2017Date of Patent: April 14, 2020Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Henry R Wright, Brandon M Fell, Martin Gentile, Rainer Kloesel, Falko Hendrischke, Julian Heinz, Marcel Wachtel

Publication number: 20110035124Abstract: A method is provided for operating an automatic transmission for a vehicle, that includes, but is not limited to detecting whether a target speed of the vehicle is set, calculating an optimum acceleration gear in dependence of an actual virtual accelerator pedal position, and, if the optimum acceleration gear differs from a current gear, storing the actual virtual accelerator pedal position, shifting to the optimum acceleration gear and ignoring newly calculated actual virtual accelerator pedal positions for an acceleration period of time. Since the actual virtual accelerator pedal position is stored in the case of a detected necessary gear shift and further calculated actual virtual accelerator pedal positions are ignored for a time, the operating of the transmission is based mainly on the value of the actual virtual accelerator pedal position at the time, when a necessary gear shift is detected.Type: ApplicationFiled: July 13, 2010Publication date: February 10, 2011Applicant: GM GLOBAL TECHNOLOGY OPERATIONS, INC.Inventors: Martin GENTILE, Gernot BECKER
