Abstract
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.
