Enhancing vehicle suspension system control performance based on the improved extension control

Vehicle suspension and steering nonlinear integrated system coordinated control based on human-vehicle function allocation

The coupled dynamics between the vehicle chassis suspension system and electrical power steering system(EPS) is analyzed, to establish the full-vehicle nonlinear model, EPS model, tire model and road input model. The tire’s complex nonlinear model is approximated by utilizing the least square method, so as to obtain the integrated system model with the 22-order. To simplify the nonlinear contro...

Computer Simulation on Fuzzy Control of Semi-active Suspension System Based on the Whole Vehicle

With the development of technology, new materials have been invented, which have been applied to improve the performance of structures. Recently, researchers pay their attention to controllable fluids and its applications. Magneto rheological (MR) damper is a kind of devices that uses rheological fluids to modify their mechanical properties. Their mechanical simplicity, large dynamic range, low...

System Approach to Vehicle Suspension System Control in CAE Environment

In recent years, motor vehicles industry has shown a tendency of replacing electromechanical components by mechatronic systems with intelligent and autonomous properties. The integration of hardware components and implementation of advance control function characterize this replacement. In this paper, we have applied the system approach and system engineering methods in the initial phase of veh...
