<P>PROBLEM TO BE SOLVED: To provide a control device which restrains a vehicle from causing vibration or noise in a drive unit for the vehicle which is provided with a differential mechanism functioning as an electrical differential device by means of differential action. <P>SOLUTION: In transmission mechanism 10 which is provided with a stepless changed-speed part 11 which is configured to be capable of shifting in stepless changed-speed state and in stepped changed-speed state, the stepless transmission 11 is preferentially shifted to the stepless changed-speed state by a change-over control means 50 so that torsional resonance of a driving system which makes vibrational noise of the vehicle as predetermined value or more does not occur. In the stepless changed-speed state of the stepless changed-speed part 11, the control device is restrained the torsional resonance of the driving system from being occurred and thereby, being restrained the vibrational noise of the vehicle from being occurred since being positively controlled to rotate so that engine rotating speed NE avoids predetermined engine rotating speed region as vehicle state easy to cause the torsional resonance of the driving system using a primary electric motor M1 by resonance restraint control means 86. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
