ABSTRACT:
A vehicle drive apparatus is provided that comprises first and second drive sources, a main clutch, a subordinate clutch, a drive source selecting section, and a clutch control section. The first and second drive sources output drive forces to a first wheel. The main clutch is configured to simultaneously shut off delivery of outputs from the first and second drive sources. The subordinate clutch coupled to the first drive source is configured to shut off delivery of only the output from the first drive source. The drive source selecting section is configured to select at least one of the first and second drive sources to output the drive force. The clutch control section is configured to release the subordinate clutch while the main clutch is temporality released upon a determination of the first drive source being switched from an output delivery state to an output stop state.
