An electric vehicle drive unit includes: first and second traveling motors that include first and second rotors, respectively; and a first planetary gear mechanism that includes first to third rotation element, The first rotation element is rotatably coupled to the first rotor. The second rotation element is rotatably coupled to the second rotor via a connection portion. The third rotation element is coupled to an output shaft coupled to a drive wheel side. Rotary axes in the first planetary gear mechanism, the first traveling motor and the second traveling motor are coaxially arranged. The electric vehicle drive unit further includes a clutch that disconnectably connects any two rotation elements among the first to third rotation elements to switch the two rotation elements to a directly coupled state at the time of connection.

A method of compensating for magnetic flux resulting from variance from a first electric machine to a second electric machine. A magnetic flux change for the first machine is calculated as a function of a flux difference between the first machine and the second machine. Operation of the first machine is controlled using the magnetic flux change.
