Abstract
In the vehicle using the three-channel anti-lock control method based on the front wheel independent-and-rear wheel select-low, only when the third system speed Vs3 to which the left and right rear wheels belong is subjected to the anti-lock control due to the abruptly decreasing of the third system speed before at least one of the left and right front wheel systems begin to be subjected to the anti-lock control, the decrease of the brake hydraulic pressure is not started even if the third system speed Vs3 becomes lower than the above threshold speed VT1 (Vs3<VT1). In such case, only when the third system speed Vs3 becomes equal to or lower than the reference speed Vr (Vs3.ltoreq.Vr), the decrease of the hydraulic pressure is started. By doing so, an excessive decrease of the brake hydraulic pressure in the third system at the time of the braking during the turning of the vehicle is prevented.
