A driving force control apparatus is configured to automatically apply a braking force to a plurality of wheels in order to descend down a hill at a constant speed, such that the wheels can be prevented from being locked by the braking force, and the vehicle speed can be prevented from increasing. In order for a vehicle to travel at a preset speed, the vehicle driving force control apparatus detects the speeds of the wheels subjected to a braking force, and switches the vehicle from a four-wheel drive (4WD) mode in which driving force is distributed to all of the wheels to a two-wheel drive (2WD) mode in which driving force is distributed to only the front wheels. The switch is made when the vehicle speed is equal to or less than a lower limit threshold. The front wheels are prevented from locking, and increases in the vehicle speed are suppressed.
