Abstract
A driving force control method is executed in a vehicle including first and second electric motors, and distributes a requested driving force for driving at a predetermined distribution ratio according to a traveling state and outputs the requested driving force by the first and second electric motors. The method includes: transferring an output torque from one electric motor to the other in response to a change in the distribution ratio based on the traveling state; setting a slip state parameter indicating a slip state; when the slip state parameter is equal to or smaller than a predetermined threshold value, setting an upper limit of a change speed of the output torque to be transferred to a first upper limit value that is small; and when the slip state parameter exceeds the threshold value, setting the upper limit of the change speed to a second upper limit value that is large.
