Abstract: An electronic control unit sets a drivability target engine speed, sets upper limit engine power on the basis of the drivability target engine speed, and sets upper limit drive power by dividing the upper limit engine power by a rotational speed of a driveshaft. Then, the electronic control unit compares accelerator requested drive power with the upper limit drive power, sets target engine power such that lower one of the accelerator requested drive power and the upper limit drive power is output to the driveshaft, and controls an engine, a first motor, and a second motor such that the target engine power is output from the engine. In this way, a driver can receive further favorable drive feeling.

Abstract: A plurality of virtual gear positions are established by an electric continuously variable transmission, and the number of speeds of the virtual gear positions is equal to or larger than the number of speeds of mechanical gear positions of a mechanical stepwise variable transmission. One or two or more virtual gear positions is/are assigned to each mechanical gear position, and shifts among the mechanical gear positions are performed in the same timing as the shift timing of the virtual gear positions. Thus, shifting of the mechanical stepwise variable transmission is accompanied by change of the engine speed Ne, and the driver is less likely to feel uncomfortable even if shift shock occurs during shifting of the mechanical stepwise variable transmission.
