A vehicle driving device includes a high-voltage battery (B1), a voltage converter (12) capable of converting a voltage of the high-voltage battery (B1) to a voltage ranging from the voltage of the high-voltage battery (B1) to a predetermined upper limit voltage, an inverter (22) supplied with a power-supply voltage from the voltage converter (12), a driving motor (MG2) driven by the inverter (22), and a control device (30) for controlling the voltage converter (12) and the inverter (22). The control device (30) determines whether or not to limit an upper limit voltage of the voltage converter (12) smaller than the predetermined upper limit voltage on the basis of a usage environment or usage load of a vehicle. In the case where the upper limit voltage of the voltage converter (12) is limited smaller than the predetermined upper limit voltage, the control device (30) drives the inverter (22) after limiting a request torque on the basis of an accelerator pedal operation performed by a driver. |
