Abstract

A hybrid vehicle control device is provided with at least one controller that controls the outputs of the engine and of the motor according to the driving state, the engagement and disengagement of the clutch, and the transmission ratio of the continuously variable transmission. The at least one controller is programmed to start the engine and forcibly downshift the continuously variable transmission to a transmission ratio with which it is possible to start on an uphill road upon determining that the vehicle is on an uphill road while in an electric vehicle mode in which it is possible to travel by the drive force of the motor with the clutch released and the engine stopped.
