Un-sprung mass direction control, sprung mass rolling, pitching and ride comfort control are the essential integrated chassis control for vehicle. The first control, it utilizes direct yaw moment by independent wheel braking and drive and active steering. The second control, it uses varied independent damper constant and excitation force on suspension. This paper propose a design of fuzzy control to control independent full car suspension by considering brake and drive excitation and finally investigate the response of rolling, pitching of the sprung - mass. First step was developed mathematical model of full car suspension with considering the brake and drive excitation of each wheel. Second step designing the fuzzy control and investigate the response of rolling and pitching. Result of experiment shown, that the fuzzy intelligent control of suspension with considering the brake and drive force excitation has better rolling, pitching and ride comfort control in the form sixth time shorter to perform convergence time (1,5 seconds) compared with PID (7 seconds) in isolate the road, brake and drive disturbance. © 2020 Institute of Physics Publishing.
