<p>In a controller of a vehicle transmission, the transmission includes a continuously variable transmission 3 and a planetary gear mechanism 4 and is coupled to an output of an engine 1. The transmission includes a first shift mode using only the continuously variable transmission 3 and a second shift mode using in combination the continuously variable transmission 3 and the planetary gear mechanism 4.The controller determines the shift mode based on load of the engine 1 according to a required output and an input/output revolution speed ratio gamma of the continuously variable transmission 3, and switches between the above two shift modes at the predetermined input/output revolution speed ratio.</p> |
