VIBRATION CONTROL DEVICE AND VIBRATION CONTROL METHOD OF HYBRID VEHICLE

Japanese Patent JP3935111

B2

PROBLEM TO BE SOLVED: To provide a vibration control device by which vibrations of two degrees of freedom of a planetary gear mechanism are effectively controlled, and as a result, strength and a cost are made lower without sacrificing the endurance of components of the planetary gear mechanism, and vibrations and unpleasant noises of drive output torque are reduced.
SOLUTION: A hybrid car includes a main power source, a plurality of auxiliary power sources, and the planetary gear mechanism to change a gear ratio required when an output of the main power source is transmitted to a drive output member, wherein two motors of a first motor MG1 and a second motor MG2 that can control torques of the power sources are selected, and signals to control vibrations are superimposed upon torque commands T1, T2 issued to the two motors of the first motor MG1 and the second motor MG2, by which a vibration control 26a controlling vibrations of the two degrees of freedom of the planetary gear mechanism is equipped.
