ABSTRACT:
The method includes: a step of calculating wheel rotation information; a judgment step of judging a decrease in a tire air pressure by comparing a predetermined reference value with a decreased pressure judgment value showing a wheel speed ratio of the front and rear axes; an initialization step of storing the wheel speed ratio between the front and rear axes at the regular internal pressure; and a step of determining whether the distribution of the front and rear driving torque is equidistribution or not.
