Abstract
Official abstract text for this publication.
A vehicle transmission apparatus configured such that when transitioning to an actual traveling state by forming one of the shift speeds from a free running state in which a vehicle is in a traveling state and the speed change mechanism is in a neutral state with none of the shift speeds formed, the control device performs a control to determine from the plurality of shift speeds one final target shift speed according to at least a vehicle speed and a driver request, and an intermediate target shift speed with a speed ratio smaller than that of the final target shift speed, and to form the final target shift speed after formation of the intermediate target shift speed.
First claim
Opening claim text (preview).
What is claimed is: 1. A vehicle transmission apparatus comprising: an input member drive-coupled to an engine; an output member drive-coupled to a wheel; a speed change mechanism that includes a plurality of engagement elements and forms a plurality of shift speeds by engagement and release of the plurality of engagement elements, each of the plurality of shift speeds having a speed ratio, respectively, and each of the speed ratios being fixed and unchanging in value, the spe…
