Basic Operation

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

Starting (Drive by MG2) 

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

During Acceleration with Engine 

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.

Charge The HV Battery 

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

During Deceleration Driving 

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.
