Creation of means of effective protection from external dynamic effects has always been one of the most important problems of modern equipment. The aim of this work is to increase smooth running of multi-wheeled vehicles using an adaptive control of elastic-damping elements of the suspension system. On the basis of application of methods of fuzzy logic, adaptive laws of a continuous suspension control system of multi-wheeled vehicles, namely the “inertial damper” adaptive law and the adaptive law of the counteraction of a linear-angular fluctuations, were developed. Methods of simulation modeling were used to determine that efficiency (reduction of the variance of the vertical accelerations at the driver's place compared to the unmanageable adaptive suspension) of the “inertial damper” law is 7...20%; one of the laws of counteraction of linear-angular fluctuations - 0...13%.

One of the promising ways to solve the problems of improving smoothness of motion of multi-wheeled vehicles (MWV) is development of suspension control systems to ensure stabilization of the MWV’s housing under different influences. On the basis of application of methods of fuzzy logic an adaptive proportional differential law of continuous MWV suspension control was developed. Methods of simulation modeling were used to analyze efficiency of the developed control law for active and semi-active suspension systems. It was shown that the proposed adaptive proportional differential law for semi-active suspension system could be considered more preferable for practical application in MWV suspensions in comparison with the similar law for active suspension systems due to their similar efficiency and lower energy costs.
