US 2008/0156550 A1 · HYBRID VEHICLE AND HYBRID POWER SYSTEM

Abstract

A hybrid vehicle is provided with an engine, a starter generator motor, a traction motor, an automatic manual transmission system, a battery, an automatic-switching clutch, and a control unit assembly. The starter generator motor is coupled and synchronously rotates with the engine for starting the engine and serving as an assistant power. The automatic manual transmission system is coupled with the traction motor and performs a gear-shifting/speed changing by controlling the rotation speed of the starter generator motor and the traction motor. The automatic-switching clutch is coupled between the starter generator motor and the automatic manual transmission system to make them be engaged/disengaged so as to switch the power type. The hybrid vehicle control device gives a signal to the torque/rotation speed control device to control the automatic-switching clutch to engage/disengage the engine and the traction motor according to the running state of the vehicle.
