1. A driving force control apparatus, comprising:
a sensor configured to collect information associated with a state of a vehicle;
a driving device including at least one of an engine or a motor and configured to provide a driving force to a drive wheel of the vehicle; and
a processor electrically connected with the sensor and the driving device,
wherein the processor is configured to:
calculate a required driving force of a driver based on at least a portion of information collected by the sensor, in a situation where the vehicle is turning;
calculate a limit driving force based on (i) a minimum value between a maximum driving force of a left drive wheel and a maximum driving force of a right drive wheel tire of the vehicle, and (ii) an estimated lateral force for a tire of the vehicle;
compare the required driving force with the limit driving force;
calculate a braking force when the required driving force exceeds the limit driving force; and
provide the calculated braking force to a braking device,
wherein the limit driving force corresponds to a maximum driving force at which the vehicle maintains lateral stability while the vehicle is turning.
