PURPOSE: A four-wheel driving controller is provided to distribute driving force of the four-wheel driver with an electromotive hydraulic device. CONSTITUTION: A center differentiator(12) receives power of an engine(8) from an output gear(6) of a transmission(4) through a ring gear(10). An increase/decrease gear set(18) controls rotating force of the differentiator(12) according to loaded states of a front wheel and a rear wheel. A differentiator for the front wheel(24) transmits the distributed rotating force from a left side gear(20) to the front wheel(14) through a first hollow shaft. A differentiator for the rear wheel(32) transmits the distributed rotating force from a right side gear(26) to the rear wheel(12) through a second hollow shaft(28). An ECU(Electronic Control Unit) distributes the driving force by discriminating speeds of the wheels, a rotating angle of a steering wheel, a horizontal acceleration and a throttle opening. An electromotive hydraulic device(38) controls hydraulic pressure to distribute the driving force into the wheels.
