A vehicle drive device includes a control portion that is allowed to execute a control mode that controls multiple hydraulic elements to cause a vehicle in a stop state of an engine to start moving. The control mode starts controlling part of the multiple hydraulic elements before the engine is started, by using oil pressure accumulated in an accumulator (S). The control mode starts controlling the rest of the multiple hydraulic elements by using oil pressure that is provided after the engine is started (S).

Vehicle drive device and method of controlling vehicle drive device

A control device that controls an inverter interposed between a DC power source and an AC rotary electric machine to perform power conversion between DC power and AC power, wherein the inverter includes a plurality of sets of an upper switching element and a lower switching element connected in series with each other between positive and negative electrodes on the DC side and controlled so as to be turned on and off in a complementary manner; and the control device executes short-circuiting processing, in which all the upper switching elements or all the lower switching elements are controlled so as to be turned on, while the AC rotary electric machine is stationary.
