Abstract
A power distribution control system for an automotive vehicle, takes an approach for projecting vehicle speed representative value on the basis of a wheel speed latched immediately before initiation of wheel speed variation irrespective of the vehicle speed, and a predetermined variation rate of the vehicle speed. The vehicle speed representative value is derived as a function of time by taking the latched wheel speed as an initial value. The projected vehicle speed data is utilized with other preselected power distribution control parameters for controlling distribution ratio of driving power for a primary and a subsidiary driving wheels.
