ABSTRACT:
A power distribution control system system takes a strategy for adjusting power distribution to vary control mode in order to avoid influence of variation of wheel speed difference between a primary driving wheel directly or permanently connected to a vehicular prime mover, i.e. an automotive internal combustion engine and thus having greater inertia and an auxiliary driving wheel having smaller inertia. For this, occurrence of hunting in power distribution control is detected. As long as hunting is not detected, the wheel speed difference dependent power distribution control mode is selected for controlling power distribution depending upon a wheel speed difference between the primary and auxiliary wheels. On the other hand, when the hunting in wheel speed difference dependent power distribution control is detected, the control mode is switched from the wheel speed difference dependent power distribution control mode to the vehicular acceleration dependent power distribution control mode in which power distribution control is derived on the basis of the vehicular acceleration.
