Vehicle drive device

A vehicle drive device comprising:

• a wheel drive rotary electric machine and a transmission device on a power transmission path connecting an input member drivingly coupled to an internal combustion engine and an output member drivingly coupled to wheels;
• a pump electric motor that serves as a driving force source of a hydraulic pump;
• a case that accommodates the wheel drive rotary electric machine, the transmission device, and the pump electric motor;
• a motor controller including a first inverter that controls the wheel drive rotary electric machine, a second inverter that controls the pump electric motor, a cooler that cools the first inverter and the second inverter, and a smoothing capacitor that smooths direct-current power to be supplied to the first inverter and the second inverter, wherein
• a rotational axis of the input member and a rotational axis of the transmission device are aligned in a vehicle width direction;
• in the motor controller, an inverter unit and the smoothing capacitor are arranged in a vehicle front-rear direction in an upward direction of the case, the inverter unit including the first inverter, the second inverter, and the cooler;
• and
• one of the inverter unit and the smoothing capacitor having a smaller thickness in a vehicle up-down direction than the other is disposed in an upward direction of a highest located member, the highest located member being a member located at a highest position in a region of the case overlapping the motor controller as viewed in the vehicle up-down direction;
• and
• a through connection terminal that is a relay connection terminal disposed on an electrical connection path electrically connecting a coil of the wheel drive rotary electric machine and the first inverter and that extends through the case, and an intermediate connection terminal that is a relay connection terminal disposed on an electrical connection path connecting the through connection terminal and the first inverter;
• wherein
• the through connection terminal is disposed in a downward direction of the inverter unit or the smoothing capacitor;
• and
• the intermediate connection terminal is disposed between the first inverter and the smoothing capacitor, in a region not overlapping both of the first inverter and the smoothing capacitor, as viewed in the vehicle up-down direction.
