PURPOSE: A device for controlling the roll stiffness of cars is provided to move the fixing location having a step bar without suing a step bar link according to the car driving state, thereby largely improving the driving safety by making the roll stiffness suitable for driving situation actively. CONSTITUTION: A device for controlling the roll stiffness of cars includes a step bar(1), a variable unit(4), and a sensor(2). The step bar is continued to a low arm(L) by arranging a device controlling the roll stiffness along a sub frame(S). A variable unit changes the roll stiffness having the step bar. The variable unit moves the fixing location of the step bar located to the low arm side. The step bar is comprised of one bar, which both side is bent, to be located to low arm mounted to both sides of the sub frame. The sensor comprised of a acceleration sensor(2a), a steering angle sensor(2b), and a garage sensor(2c). |
