Transmission Control System

A method (200) for open-loop control of a gearbox (100) that includes a first proportionally controllable shift element (A-F) and a second proportionally controllable shift element (A-F), the method (200) comprising:

• disengaging the first shift element (A-F) of the gearbox (100) according to a first control profile;
• and
• engaging the second shift element (A-F) of the gearbox (100) according to a second control profile,
• wherein the first control profile comprises a variable portion (330) which increases between a first point in time (t4) and a second point in time (t5), a gradient (335) of a rotational speed of an input shaft of the gearbox (100) reaches a predetermined threshold value at the first point in time (t4), and the gradient (335) flattens at the second point in time (t5).

A device (125) for open-loop control of a gearbox (100) that includes a first proportionally controllable shift element (A-F) and a second proportionally controllable shift element (A-F), the device comprising:

• a first interface for connection to the first shift element (A-F);
• a second interface for connection to the second shift element (A-F);
• a processing unit (125);
• and
• a memory storing computer-executable instructions that, when executed by the processing unit (125), cause the processing unit (125) to perform operations comprising
• disengaging the first shift element (A-F) according to a first control profile;
• and
• engaging the second shift element (A-F) according to a second control profile,
• wherein the first control profile comprises a variable portion (330) which increases between a first point in time (t4) and a second point in time (t5), a gradient (335) of the rotational speed of an input shaft of the gearbox (100) reaches a predetermined threshold value at the first point in time (t4), and the gradient (335) flattens at the second point in time (t5).
