Abstract
A control system for a four-wheel drive vehicle includes a center differential provided between a front shaft and a rear shaft. The control system also includes a device for restricting a differential between the front shaft and the rear shaft by operating the center differential to be in a locking condition and a controller for controlling the differential restricting device so that a differential restricting force is increased based on an increase in an engine output. The differential restricting force is decreased based on an increase in a vehicle body speed.
