Hybrid vehicle

Abstract

A hybrid vehicle which can run under a heavy load without requiring an electric motor large in size or an inverter element of large capacity. The hybrid vehicle includes an internal-combustion engine, an electric machine unit to which the rotation of the internal-combustion engine is input, an electric motor driven by electric current supplied thereto, a differential gear unit including at least three gear elements with a first gear element connected to the electric machine unit, a second gear element connected to an output shaft, and a third gear element connected to the internal-combustion engine, and a stopping device for stopping the rotation of the third gear element. Since the hybrid vehicle can be driven by the driving force of the electric machine unit, the driving force and torque constant of the electric motor can be reduced to that required of the electric machine unit so that the electric motor need not be large in size.
