Abstract
The control procedure of the invention sets a target rotation speed Ne* and a target torque Te* of an engine corresponding to a torque demand Td* required for driving the vehicle (steps S100 to S120). In response to an upshift request for a gear of a transmission, the control procedure sets a positive pre-upshift target rotation speed Nmtag to a target rotation speed Nm1* of a first motor (step S230). The control procedure changes the target rotation speed Ne* of the engine to a specific rotation speed corresponding to the pre-upshift target rotation speed Nmtag of the first motor (step S240) and subsequently implements an actual change of the gear in the transmission (step S310). This arrangement effectively restrains a battery from being overcharged with excess electric power.
