Abstract: <P>PROBLEM TO BE SOLVED: To highly accurately suppress torque variation of a driving shaft of a wheel when an engine is started by a first MG (motor generator), in a hybrid electric vehicle which mounts an engine and first and second MGs.  <P>SOLUTION: When starting the engine by cranking the engine with torque of the first MG, variation of inertia torque is reduced by correcting the torque (cranking torque) of the first MG according to an engine crank angle so as not to change the increase of engine rotation speed. After reducing the variation of cranking reaction force torque which reduces variation of the inertia torque by torque control of this first MG and acts on driving shaft, the torque of the second MG is controlled to cancel the cranking reaction force torque (that is, torque of small variation). Thereby, torque variation of the driving shaft is suppressed with high accuracy by canceling the cranking reaction force torque which acts on the driving shaft by torque control of the second MG with high accuracy.  <P>COPYRIGHT: (C)2008,JPO&INPIT
