Patent number: 11619299Abstract: A method for operating a hybrid transmission includes monitoring the surroundings of a motor vehicle and, based on the data ascertained within the scope of the monitoring, determining a probability of occurrence of a driving situation to be anticipated, which, upon occurring, results in a deceleration of the motor vehicle. Based on the determined probability of occurrence, it is decided whether to carry out an electrodynamic gear shift or an output-assisted gear shift in order to transfer the hybrid transmission out of an operating condition, in which a gear is engaged, into a shift condition.Type: GrantFiled: October 16, 2018Date of Patent: April 4, 2023Assignee: ZF FRIEDRICHSHAFEN AGInventors: Uwe Griesmeier, Johannes Kaltenbach
