SYSTEM DESCRIPTION

1. BASIC OPERATION

(a) This system generates a motive force in combination with the engine, MG1, MG2, and MGR in accordance with the driving conditions. Representative examples of the various combinations are described below.

(b) Front Wheel Operation:

(1) Supply of electrical power from the HV battery to MG2 provides force to drive the front wheels.





(2) While the front wheels are being driven by the engine via the planetary gears, MG1 is driven by the engine via the planetary gears, in order to supply the generated electricity to MG2.





(3) MG1 is rotated by the engine via the planetary gears, in order to charge the HV battery.





(4) When the vehicle is decelerating, kinetic energy from the front wheels is recovered and converted into electrical energy and used to recharge the HV battery by means of MG2.





(c) Rear Wheel Operation:

(1) To ensure the proper driving force of the vehicle during start-off or acceleration, the electrical power of the HV battery is supplied to MGR in order to drive the rear wheels.





(2) During the full throttle acceleration of the vehicle, both the electrical power of the HV battery and the electrical power generated by MG1 are supplied to MGR in order to drive the rear wheels.





(3) When the vehicle is decelerating, kinetic energy from the rear wheels is recovered and converted into electrical energy and used to recharge the HV battery by means of MGR.
