Abstract

A traction control apparatus for a four-wheel drive vehicle simultaneously sets an equal control amount &Dgr;VWRL=&Dgr;VWRR for brake devices on the side of rear-left and rear-right wheels if at least one of the rear wheels is driven with a low grip degree. Thereby the slip tendency of the rear wheels is weakened, and the behavior of the vehicle is shifted in a stabilizing direction.
