Abstract:
1. A controller including an internal combustion engine and a continuously variable transmission, wherein a transmission coupled to an output of the internal combustion engine includes the continuously variable transmission and a gearshift mechanism, and the controller is capable of selectively setting a first shift mode in which a gear ratio increases with increase in an input/output revolution ratio, that is, a ratio between an input revolution speed and an output revolution speed of the continuously variable transmission, and a second shift mode in which the gear ratio decreases with increase in the input/output revolution ratio, the controller comprising: an internal combustion engine control means for obtaining target torque based on control data including a required output, and controlling load of the internal combustion engine so as to achieve the target torque; an input/output revolution ratio calculating means for obtaining a target input revolution speed based on the control data and calculating the input/output revolution ratio of the continuously variable transmission so as to achieve the target input revolution speed; and a shift-mode determining means for determining a shift mode to be set from the first shift mode and the second shift mode based on the input/output revolution ratio calculated by the input/output revolution ratio calculating means.
