PURPOSE:To improve the slip convergence of a slipping wheel by preventing the increase in distributed torque by means of torque distribution control for a slip control target wheel when torque distribution control is going to be carried out for the wheel where slip control is being carrying out. CONSTITUTION:Propeller shafts 24, 26 for front and rear wheels are connected to the output side of an engine 12, in which a throttle valve 14 electrically driven and controlled is installed in an intake passage 16, through a transmission 22 and a center differential mechanism 23 to enable torque distribution quantities to respective shafts 24, 26 to be controlled. In such a device, a judging means which judges whether the torque transmitted, by action of the center differential mechanism 23, to the wheel where slip control is being carried out so that the slipping quantity of a slipping wheel may be below a prescribed level is increased or not is provided in a control 100. At the time of the judgment of YES, control is made so that the transmitted torque at least for a slip control target wheel may be decreased so as to restrain the transmitted torque to the wheel. |
