PURPOSE:To aim at the promotion of reduction in a braking distance, by setting plural conditions judging a road state as a crown mu road, and when these plural conditions are simultaneously materialized, quickening this time pressure starting point after being changed to that point reached to the specified reference speed. CONSTITUTION:In this method, there are provided with each of arithmetic circuits 5-8 which operate each wheel speed from each output of speed sensors 1-4 additionally installed in each wheel, and symmetrical front-wheel speed signals are inputted into control logic circuits 9 and 10. And, in symmetrical rear-wheel speed signals, a signal at the low speed side is inputted into a control logic circuit 12 from a low select circuit 11 and an all-wheel speed signal into a pseudo-body speed arithmetic circuit 13, respectively. And, when deceleration of pseudo-body speed is more than the specified value and a slip factor in a low peak point of control system wheel speed Vw is less than the specified percentage, as well as when mean acceleration at time of the wheel speed Vw being restored is more than the specified value, the pressure starting point at this time is constituted so as to be changed to that point reached to the reference speed after the wheel speed Vw elapses since the low peak point.
