Abstract: The present invention executes a desired gear shift of an automatic transmission using gear shift modeling even when there are three control inputs to two target gear shift values. Setting torque share ratio as a constraint on the equation of motion for the automatic transmission is suitable for controlling the transfer of engaging unit torque, which is considered to be difficult in variable speed control, and allows solving of the equation of motion. Viewed from a different angle, because the torque share ratio, which represents the torque transfer, has been set as a constraint, any gear shift pattern can be handled with a single gear shift model.
