发明名称 METHOD FOR ACTUATING A SHIFTING OPERATION IN AN AUTOMATIC TRANSMISSION OF A UTILITY VEHICLE
摘要 <p>A method of controlling a shifting operation in an automatic transmission of a commercial vehicle. A targeted gear and an associated target rotational speed are determined, via a transmission control, depending on predetermined parameters, and the shifting operation is executed upon reaching a determined shifting rotational speed. A shift interlock is activated, at least temporarily, during a downshifting operation when, upon reaching the shifting rotational speed, the determined target rotational speed lies below a predetermined rotational speed limit.</p>
