1. A method of controlling driving force of a vehicle, the method comprising:
determining a natural frequency of vehicle suspension pitch motion according to characteristics of a suspension device of the vehicle;
providing a first filter for removing or reducing the natural frequency of the vehicle suspension pitch motion, and a second filter for extracting or increasing the natural frequency of the vehicle suspension pitch motion to a controller of the vehicle;
determining, by the controller, a required driving force command based on vehicle driving information collected during driving of the vehicle;
determining, by the controller, a driving force command after filter application through a processing process by the first filter taking the determined required driving force command as input thereof;
determining, by the controller, a driving force correction amount through a processing process by the second filter taking feedback driving force as input thereof, the feedback driving force being a feedback value of a vehicle driving force; and
correcting, by the controller, the driving force command after the filter application using the driving force correction amount and controlling driving force applied to a driving wheel of the vehicle by a driving device of the vehicle using the driving force command after the correction.
