In rollover prevention control, an inner front wheel braking force is generated only in a front wheel located on the radially inner side of a turning locus in a relatively early stage where the absolute value of actual lateral acceleration is between a first value and a second value. When the absolute value becomes greater than the second value, in addition to the inner front wheel braking force, an inner rear wheel braking force is generated in a rear wheel located on the radially inner side of the turning locus. When the absolute value becomes greater than a third value, in addition to the inner rear wheel breaking wheel, an outer wheel braking force is generated in the front wheel located on the radially outer side of the turning locus. Thus, an increase in the roll angle is suppressed, and a desired turning locus tracing performance is maintained satisfactorily.
