ELECTRICALLY-PROPELLED VEHICLE DRIVINGLY CONTROL DEVICE AND ELECTRICALLY-PROPELLED VEHICLE DRIVINGLY CONTROL METHOD

摘要

PPROBLEM TO BE SOLVED: To increase the durability of a differential rotating unit. PSOLUTION: This device comprises an electric machine, an output shaft 14 differentially and rotatably connected to an engine and the electric machine, a differential rotating unit in which a rotating body having a first differential rotating element connected to the electric machine, a second differential rotating element connected to the output shaft 14, and a third differential rotating element connected to the engine and rotatably disposed on a support shaft in one of the first to third differential rotating elements and the other two differential rotating elements are rotatingly engaged with each other, and an engine control treatment means for controlling the engine based on the rotational speed of the rotating body. Since the engine is controlled based on the rotational speed of the rotating body, the rotational speed of the rotating body can be prevented from increasing over an upper limit value.
