Abstract
A drive-force control apparatus for a vehicle including a first drive apparatus for driving a first pair of wheels and a second drive apparatus for driving a second pair of wheels. Each of the first pair of wheels is one of front and rear wheels of the vehicle, and each of the second pair of wheels is the other of the front and rear wheels. During running of the vehicle on a wave-like road, the control apparatus reduces a drive-force share ratio of one of the first and second drive apparatuses, and to increases a drive-force share ratio of the other of the first and second drive apparatuses, wherein the one of the first and second drive apparatuses includes a weakest part that is to be damaged the most easily among parts composing the first and second drive apparatuses, by resonance caused by the running on the wave-like road.
