Transmission control system

A gearbox (100) includes an input shaft (105) and a first and a second proportionally controllable shift element (A to F). The shift elements (A to F) are configured to control, by way of an open-loop system, engagement or disengagement of a gear ratio in the gearbox (100). A method (200) for the op...

Beschreibung
Zusammenfassung:	A gearbox (100) includes an input shaft (105) and a first and a second proportionally controllable shift element (A to F). The shift elements (A to F) are configured to control, by way of an open-loop system, engagement or disengagement of a gear ratio in the gearbox (100). A method (200) for the open-loop control of the gearbox (100) includes: determining a specified differential speed profile that is a profile of a difference between a rotational speed of the input shaft (105) and a synchronous speed of a gear ratio to be engaged; and determining a torque demand of a drive source connected to the input shaft (105) or determining a control profile for the one of the first and second shift elements (A to F) to be engaged in the gear ratio on the basis of the specified differential speed profile.
