Drive Force Control Method and Drive Force Control Device

A drive force control device that determines a torque distribution ratio between drive devices provided in a vehicle that are capable of driving independently in a front-rear direction, to cover an in-phase range in which signs of output torques of the drive devices are equal, and an out-of-phase range in which the signs are different from each other, the drive force control device comprising:

• a control unit configured to execute backlash reducing control of limiting a magnitude of the output torque of one of the drive devices whose sign is inverted during phase transition to a magnitude of a basic command torque determined according to the torque distribution ratio, wherein the control unit is configured toto:
• start the backlash reducing control when the basic command torque reaches a predetermined control start torque;
• and
• set, during acceleration and/or deceleration of the vehicle, the control start torque to a correction control start torque different from a basic control start torque used during constant speed traveling.
