Abstract
A driving force control system for a front-and-rear wheel drive vehicle, which is capable of charging a battery based on a traveling condition of the vehicle. The front-and-rear wheel drive vehicle is driven while switching between a drive mode for driving front wheels by an engine and driving rear wheels by a motor, and a recharge mode for recovering running energy of the vehicle and charging the battery with the recovered running energy. Parameters (accelerator pedal opening &THgr;AP and a vehicle speed Vcar, or drive wheel speeds of the respective front and rear wheels) indicative of a driving condition of the vehicle are detected. A traveling condition of the vehicle is determined based on the parameters. It is determined, based on the traveling condition of the vehicle and the state of charge of the driving energy in the drive source, whether charging of the battery is to be executed.
