PROCÉDÉ DE COMMANDE DE PUISSANCE ET DISPOSITIF DE COMMANDE DE PUISSANCE POUR VÉHICULE HYBRIDE

摘要

Provided are a driving force control method and device for a hybrid vehicle, each capable of effectively absorbing torque fluctuation of an engine while suppressing deterioration in energy efficiency. The driving force control device for a hybrid vehicle comprises a PCM (14) configured to: identify a speed reduction ratio in a driving force transmission mechanism; estimate an average torque output by an engine (2); estimate a torque fluctuation component of the torque output by the engine; set a countertorque for suppressing the estimated torque fluctuation component; and control an electric motor to output the set countertorque, wherein the PCM is operable, under a condition that the average torque output by the engine and an engine speed are constant, to set the countertorque such that, as the speed reduction ratio becomes smaller, the absolute value of the countertorque becomes larger.
