    Abstract: When a power transmission path of a power transmission system is set to a second power transmission path, a continuously variable transmission is controlled at a speed ratio (γ) that provides a higher vehicle speed in the case where an input shaft angular acceleration (dωi/dt) is small than in the case where the input shaft angular acceleration (dωi/dt) is large. Therefore, it is possible to control the speed ratio (γ) of the continuously variable transmission to a speed ratio (γ) that reflects an inertial loss (Tli) of the continuously variable transmission. The inertial loss (Tli) changes with the input shaft angular acceleration (dωi/dt). Thus, in a vehicle in which the continuously variable transmission and a gear mechanism are provided in parallel with each other between an input shaft and an output shaft, it is possible to appropriately reduce a loss of the idling continuously variable transmission.
