HYBRID VEHICLE CONTROL DEVICE

The purpose of the present invention is to provide a hybrid vehicle control device with which it is possible to prevent a delay in transmission response if a mode switch request and a downshift request have been generated. Provided is a hybrid vehicle control device, in which an engine (2), a motor (4), and an automatic transmission (6) are provided to a drive system, and in which when there is a mode switch request during an EV mode where only the motor (4) is a drive source, a shift is made to an HEV mode where the engine (2) and the motor (4) are drive sources, wherein if a mode switch request and a downshift request for the automatic transmission (6) are generated, mode switch control is immediately started first. The configuration is also such that downshift control is started once the rotational speed of the engine (2) has reached a combustion possible rotational speed, and the transmission speed at this time is made to be faster than an ordinary transmission speed.
