Abstract:
A method (200) for the open-loop control of a gearbox (100) that includes a first and a second proportionally controllable shift element (A-F) is provided. The method includes disengaging (215) the first shift element (A-F) according to a first control profile and engaging (220) the second shift element (A-F) of the gearbox (100) according to a second control profile. The first control profile includes a first variable portion which is determined as a function of a temperature of the gearbox (100).
