Abstract:
A driving force control apparatus for a vehicle comprising:slip detection means for detecting a slip condition amount indicating a magnitude of a slip condition generated in driving wheels of the vehicle when starting or accelerating the vehicle; driving force control means for controlling a driving force transmitted from the driving wheels to a road surface; operation condition detection means for detecting an operation condition of the vehicle wherein a vibration occurs in the driving wheels; control means for controlling said driving force control means according to the slip condition amount detected by said slip detection means to reduce the driving force and suppress a slip of the driving wheels; and control regulation means for limiting an increase of the driving force, when said operation condition detection means detects the condition wherein a vibration occurs in the driving wheels, which is reduced by said control means, so that the increasing of the reduced driving force is made difficult, wherein said operation condition detection means determines the operation condition of the vehicle wherein a vibration occurs in the driving wheels when the vehicle is detected as traveling on a split road where frictional coefficients of the road surface contacting right and left driving wheels of the vehicle are different, and wherein said operation condition detection means includes rotational speed difference detection means for detecting a rotational speed difference between the right and left driving wheels; and split road determination means for determining that the vehicle is traveling on the split road when the rotational speed difference detected by said rotational speed difference detection means is greater than a predetermined value.
