A driving force control method for a hybrid vehicle equipped with an internal combustion engine , a driving force transmission mechanism for transmitting driving force of the internal combustion engine to drive wheels, and an electric motor coupled to the internal combustion engine and capable of outputting driving force to the driving force transmission mechanism , the driving force control method comprising the steps of: estimating an average torque output by the internal combustion engine ; estimating a torque fluctuation component of the torque output by the internal combustion engine ; setting a countertorque for suppressing the estimated torque fluctuation component; and controlling the electric motor to output the set countertorque, wherein the step of setting a countertorque includes: a sub-step of, under a condition that the average torque output by the internal combustion engine is constant, when the engine speed of the internal combustion engine is in the range of equal to or greater than a given value (Ne2) that corresponds to a resonance frequency of the vibration transmission path extending from the internal combustion engine to the floor panel of the passenger compartment, setting a negative control gain such that, as an engine speed of the internal combustion engine becomes higher, an absolute value of the control gain becomes smaller; and a sub-step of setting the countertorque based on a product of the estimated torque fluctuation component and the control gain, characterized in that the step of setting a countertorque includes a sub-step of, under a condition that the engine speed of the internal combustion engine is constant, when the average torque output by the internal combustion engine is in the range of equal to or greater than a given value (Te2) that a driving force from the internal combustion engine balances to a traveling resistance of the vehicle, setting the control gain such that, as the average torque output by the internal combustion engine becomes larger, the absolute value of the countertorque becomes smaller estimating an average torque output by the internal combustion engine ; estimating a torque fluctuation component of the torque output by the internal combustion engine ; setting a countertorque for suppressing the estimated torque fluctuation component; and controlling the electric motor to output the set countertorque, wherein the step of setting a countertorque includes: a sub-step of, under a condition that the average torque output by the internal combustion engine is constant, when the engine speed of the internal combustion engine is in the range of equal to or greater than a given value (Ne2) that corresponds to a resonance frequency of the vibration transmission path extending from the internal combustion engine to the floor panel of the passenger compartment, setting a negative control gain such that, as an engine speed of the internal combustion engine becomes higher, an absolute value of the control gain becomes smaller; and a sub-step of setting the countertorque based on a product of the estimated torque fluctuation component and the control gain, characterized in that the step of setting a countertorque includes a sub-step of, under a condition that the engine speed of the internal combustion engine is constant, when the average torque output by the internal combustion engine is in the range of equal to or greater than a given value (Te2) that a driving force from the internal combustion engine balances to a traveling resistance of the vehicle, setting the control gain such that, as the average torque output by the internal combustion engine becomes larger, the absolute value of the countertorque becomes smaller <EOS>
