An electrically operated vehicle drive controller used with an
electrically operated machine, an output shaft differentially rotatably
connected to an engine and the electrically operated machine, and a
differential rotating unit having a first differential rotating element
connected to the electrically operated machine, a second differential
rotating element connected to the output shaft, a third differential
rotating element connected to the engine, a rotating body rotatably
arranged on a support shaft in one of the first to third differential
rotating elements and meshed with the other two differential rotating
elements, and an engine control processor that controls the operation of
the engine on the basis of the rotating speed of the rotating body.
Because the operation of the engine is controlled on the basis of the
rotating speed of the rotating body, it is possible to prevent the
rotating speed of the rotating body from becoming higher than an upper
limit value.
