Abstract:
1. A slip control device of a four-wheel-drive vehicle to prevent any slip of wheels by varying the torque transmission distribution to a front wheel side and a rear wheel side via a transfer clutch, and controlling the coupling force of said transfer clutch when the wheels slip, said device comprising: means for calculating an indicated value to the coupling force of said transfer clutch in a first area in which a wheel slip quantity is not exceeding a preset value; means for correcting the indicated value to the coupling force of said transfer clutch in said first area by a correction value according to a tight cornering brake quantity; and means for calculating the indicated value to the coupling force of said transfer clutch when transferring to a second area in which the wheel slip quantity exceeds the preset value from said first area as a value of the indicated value in said first area added to the indicated value according to the slip quantity in said second area.
