发明名称 Continuously variable transmission and control method therefor
摘要 A transmission controller determines whether or not to downshift a sub-transmission mechanism based on an opening and an opening speed of an accelerator pedal and a torque change rate of an engine, and downshifts the sub-transmission mechanism when a determination is made to downshift the sub-transmission mechanism.

主权项 1. A continuously variable transmission with a variator capable of continuously changing a speed ratio and a stepped sub-transmission mechanism for shifting and outputting output ration of a power source, comprising: a downshift determining unit configured to determine whether or not to downshift the sub-transmission mechanism based on an opening and an opening speed of an accelerator pedal, which is an output adjusting device of the power source, and a torque change rate of the power source; and a shifting unit configured to downshift the sub-transmission mechanism when a determination is made to downshift the sub-transmission mechanism.
