ABSTRACT:
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.
