<P>PROBLEM TO BE SOLVED: To provide a roll rigidity control device and a roll rigidity control method that bring about the improvement and the like of controllability when a turning travel and a traffic lane change. Ž<P>SOLUTION: A roll rigidity setting section 60 judges whether or not a curvature distance Lr is a positive value (that is, whether or not travel on a turn road is finished) in step S26, because judgments from the second time onward in step S21 become Yes when the turn road exists in the forward direction of a vehicle V. Because an initial judgment in the step S26 becomes Yes, the roll rigidity setting section 60 estimates the turning radius Rt of the vehicle V with a calculation formula from current steering angle δ and vehicle velocity v in step S27. Then, in step S28, the roll rigidity setting section 60 calculates a curvature difference judgment value Dr by multiplying a predetermined correction coefficient Kc with a value obtained by reducing the turning radius Rt from a curvature radius Rc, and after that, in step S29, searches and sets rigidity distribution current values Gff, Grr from a rigidity distribution map.
