Abstract
A method for controlling driving force of a vehicle in which driving force of the vehicle is controlled by pre-reflecting vertical load information of tires in real time during turning of the vehicle, to solve repeated occurrence of wheel slip and wheel slip control performance degradation due to roll motion, includes determining, by a controller, a basic torque command in real time based on vehicle driving information obtained while driving of the vehicle, obtaining information related to left wheel and right wheel vertical loads in real time based on information collected by the vehicle, determining a torque upper limit from the real-time vertical load information, determining a final torque command limited so as not to exceed the determined torque upper limit from the real-time determined basic torque command, and controlling operation of a driving device in accordance with the determined final torque command.
