A drive train for a hybrid electric vehicle has an engine, first and
second motor/generators, a third motor, and a transmission in connecting
relationships with the engine, the motor/generators, and the third motor.
The transmission has planetary gear sets to be shifted among a plurality
of running modes including a large driving force running mode. A
controller controls surplus power caused by power balance between the
first and second motor/generators to be supplied to the third motor when
the surplus power is generated and the vehicle starts with the
transmission being operated in the large driving force running mode.
