PROBLEM TO BE SOLVED: To provide a power control method and a power control device of a hybrid vehicle which can effectively absorb torque variation of an engine while suppressing the deterioration of an energy efficiency.SOLUTION: A power control device of a hybrid vehicle estimates 36 an average torque output from an engine, estimates 38 a torque variation component of the torque output from the engine, sets 40 a counter torque suppressing the estimated torque variation component, and has a PCM which controls an electric motor so that the electric motor outputs the set counter torque. The PCM sets a negative control gain so that when the average torque output from the engine is constant, the absolute value of the negative control gain becomes smaller as an engine revolution speed becomes larger, and sets the counter torque on the basis of the product of the torque variation component and the control gain.SELECTED DRAWING: Figure 4

    【課題】エネルギー効率の低下を抑制しながらエンジンのトルク変動を効果的に吸収することができる、ハイブリッド車両の動力制御方法及び動力制御装置を提供する。【解決手段】ハイブリッド車両の動力制御装置は、エンジンが出力する平均トルクを推定36し、エンジンが出力するトルクにおけるトルク変動成分を推定38し、推定されたトルク変動成分を抑制するカウンタートルクを設定40し、設定されたカウンタートルクを出力するように電動モータを制御するPCMを有し、PCMは、エンジンが出力する平均トルクが一定の場合にエンジン回転数が大きいほど絶対値が小さくなるように、負の制御ゲインを設定し、推定されたトルク変動成分と制御ゲインとの積に基づきカウンタートルクを設定する。【選択図】図4
