Zugriff:
When all conditions for increasing a regeneration amount are established, and when a motor temperature Tmg is lower than a predetermined temperature, and a rotation speed Nm1 of a motor MG1 is lower than a predetermined rotation speed, a motor requirement upper limit value VHlimmg is set by imposing a limit for reducing a drive voltage system voltage VH (S130). In so doing, the regeneration amount can be increased by suppressing heat generation by a diode of a lower arm of a step-up converter. When, on the other hand, the motor temperature Tmg equals or exceeds the predetermined temperature or the rotation speed Nm1 of the motor MG1 equals or exceeds the predetermined rotation speed, the motor requirement upper limit value VHlimmg is set by relaxing or canceling the limit for reducing the drive voltage system voltage VH (S130).
