DTC P3147-239: Transmission system; DTC P3147-241: Transmission system [12/2014 - ]: Description

The hybrid vehicle transaxle assembly consists of the power split planetary gear unit, generator, motor, and the motor speed reduction planetary gear unit. The power split planetary gear unit uses a planetary gear to split engine output in accordance with driving requests while the vehicle is driven or the HV battery is charged. motor assists engine output while increasing vehicle drive force. motor also converts the energy, which would otherwise be consumed in the form of heat during normal braking, into electrical energy. This recovered energy is put back into the HV battery to perform regenerative braking. MG1 generates power, which is used for charging the HV battery or driving motor, and also regulates the amount of electricity being generated. In addition, generator is used as a starter motor to start the engine.
