摘要： A method and apparatus for rapidly causing a slip of a driving wheel to converge regardless of the change in vehicle conditions when the driving wheel is in a slip state. When a slip occurs on a driving wheel, a second driving force command value is calculated from a driving force control value controlled by driving force control means and an angular acceleration. The second driving force command value is calculated so that torque capable of being transmitted to a road surface by the driving wheel takes the maximum value. Therefore, even if the friction coefficient of road surface or the wheel load changes, the driving torque of driving wheel can be commanded properly, so that the slip can be converged rapidly. The occurrence of slip at the time of re-acceleration after slip convergence can be avoided.

摘要： A controller (8) controlling a drive force distributed to each wheel (1-4) of a vehicle sets dynamic drive force target values (Fxf**, Fx3**, Fx4**) to the wheels, and determines a variation amount target ratio related to variation amounts (ΔM, ΔFx, ΔFy) of a vehicle yaw moment (M), a vehicle front/aft force (Fx), and a vehicle lateral force (Fy) such that a vehicle behavior generated by the dynamic drive force target values does not vary. The controller (8) determines sets of the drive forces (Fxf(j, k), Fx3(j, k), Fx4(j, k)) realizing the variation amount target ratio, selects drive force command values from these sets such that each drive force command value is within a drive force limiting range, and controls a drive force regulating mechanism (20, 12, 13, 15,16) according to the selected drive force command values.
