Abstract
There is disclosed a driving force control system for a four-wheel drive vehicle, which is capable of properly controlling the execution and cancellation of a lock mode in which the engagement forces of clutches for distributing a driving force to auxiliary drive wheels are made maximum, thereby reducing frequency and duration of the lock mode. Further, there is disclosed a driving force control system for a four-wheel drive vehicle, which is capable of properly controlling the engagement forces of clutches for distributing a driving force of the main drive wheels to auxiliary drive wheels, thereby causing the clutches to efficiently operate without waste of power. When the vehicle is determined to be in a predetermined low vehicle speed condition, and at the same time, the shift lever of the transmission is detected to be in any of predetermined low-speed shift positions, execution of a lock mode is permitted in which the clutch engagement forces are controlled to lockable ones which can lock the main and auxiliary drive wheels to each other. When the driving force of the main drive wheels is lower than a predetermined value, the clutch engagement forces for the lock mode are limited to smaller ones than the lockable ones.
