<p><P>PROBLEM TO BE SOLVED: To provide a transmission and a method of shift control for the transmission, capable of reducing the unpleasant feeling to a driver by enabling completion of a pre-shift to a suitable change-speed stage when the change-speed is requested. <P>SOLUTION: The transmission 1 includes a change-speed stage anticipating means. A gear mechanism selection means requires a time in shifting a current change-speed stage, as a pre-shifting time for selecting the latter change-speed stage to another change-speed stage. The change-speed stage anticipating means operates the gear-mechanism selecting means while adopting a temporary change-speed stage as a subsequent change-speed stage when the temporary change-speed stage, which is estimated from a state of vehicle after the pre-shift time, the state of vehicle being relevant to each element of an anticipated change-speed stage group that is made up of one or more of a plurality of the change-speed stages that can be selected by the one of the gear-mechanism selecting means being set on one of the input shafts out of first and second input shafts, that is disconnected from a power source, coincides with an anticipated change-gear stage which corresponds to the pre-shift time. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
