ABSTRACT:
A roll control device for a four-wheeled vehicle obtains a first parameter including a component indicative of a dynamic aspect of a rolling of a vehicle body such as a time derivative of the roll angle and a second parameter indicative of the degree of progress of the rolling such as a lateral acceleration of the vehicle body during its increasing phase, and applies a roll suppress braking to at least a front wheel serving at the outside of a turn to driftout the vehicle, so as to increase the radius of the turning curve, wherein the strength of the braking is determined according to the first parameter, while the start of execution of the braking is determined according to the second parameter exceeding a threshold value determined therefor.
