Integrated Control of Vehicle Steering and Suspension Systems

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...

Modeling and Optimal Control of 4 Wheel Steering Vehicle Using LQR and its Comparison with 2 Wheel Steering Vehicle

In this paper, kinetic and kinematic modeling of a 4 wheel steering vehicle is done and its movement is controlled in an optimal way using Linear Quadratic Regulator (LQR). The results are compared with the same control of two-wheel steering case and the advantages are analyzed. In 4 wheel steering vehicles which are nowadays more applicable the number of controlling actuators are more than the...

Integrated Vehicle Control via Coordinated Steering and Wheel Torque Inputs

A controller was developed to govern the lateral position of a highway-speed vehicle using frequencyweighted coordination of front steering and torque inputs. The MISO design problem was recast as a SISO approach by using a cascaded design technique: the first step determined the relative contribution of each control input as a function of frequency; secondary design steps utilized classical SI...
