PURPOSE:To reduce the effect of an internal circulation torque with a simple structure by grouping respective wheels according to the changeover of a drive system changeover mechanism and making the control of braking liquid pressure common to wheels under the same group. CONSTITUTION:A drive system changeover mechanism comprises a four-wheel drive changeover switch 20 for changing over a two-wheel drive from/to a four-wheel drive, and a differential lock switch 21 for operating a differential limitation mechanism incorporated into a rear wheel differential device. Respective wheels are grouped according to the changeover of the drive system changeover mechanism, and the control of braking liquid pressure is made to be common to wheels under the same group. Therefore, it is possible to change the control of braking liquid pressure according to the changeover of the drive system changeover mechanism so as to minimize the effect of an internal circulation torque. Owing to this constitution, a great practical effect can be obtained with a simple structure.
