PROBLEM TO BE SOLVED: To restrict collision sound from being made in a transmission path of torque when torque transmitted from a driving force source to a tire is oscillated. SOLUTION: When a vehicle is in charge of running, reference torque transmitted from a driving force source to a tire is found, and oscillation torque is found from the reference torque. A friction coefficient between tire and road surface is controlled by transmitting oscillation torque from the deriving force source to the tire in the driving force controller. A reducer is provided in the route from the driving force source to the tire of the front wheel and the rear wheel. The driving force controller includes: a determining means (step S4) for determining whether the oscillation torque, which is transmitted through the reducer to the tire of the front wheel and the rear wheel, goes back and forth by turns on the drive side and on the generation side; and a torque distribution ratio control means (step S5) for controlling a distribution ratio of request torque transmitted to the front wheel and request torque transmitted to the rear wheel so that the oscillation torque serves as one side of the drive and generation sides when it is determined that the oscillation torque goes back and forth by turns on the drive side and the generation side.
