Abstract

A device for controlling a rolling of a four-wheeled vehicle during a turning, wherein a target deceleration Gxt and a target yaw torque Twt of the vehicle are calculated such as Gxt=(R/2Vx) Qrs Twt=(I/2Vx) Qrs wherein R is a radius of curvature of a turning course, Vx is a vehicle speed, I is an inertial yaw moment of the vehicle, Qrs is a target roll suppress quantity indicative of the degree of need of a roll suppress control, and one or both of at least a front pair or a rear pair of wheels are applied with a separately controlled braking so as to generate the target deceleration and the target yaw torque, so as thereby to suppress the rolling of the vehicle body while keeping the course of the turning radius R.
