We propose a method to control: the right and left torque distribution system of braking/driving forces, the four-wheel-steering and the active suspension cooperatively to concurrently improve maneuverability/stability and ride comfort for automobiles. Using the LQ control theory, we obtained the integrity control rule by which both the body slip angle and the yaw rate characteristics to steering input were made not only to follow the target values, but also control the swing of the body. Computer simulation confirmed that when the vehicle applied this chassis integrated control system, the effects of control for improving the vehicle performance were greater than that of the active suspension control alone. In addition, our data suggest that this system makes it possible to achieve good control effects under bad conditions such as a variety of rugged roads and the μ turbulence roads. Moreover, because this system can greatly decrease the amount of steering work required of the driver, a reduction in physical and mental load can also be expected.
