Based on the study of the dynamic characteristics, the observers for tire force, lateral and longitudinal velocity, and vehicle stability matrix are proposed. The stability matrix is used to predict t....
Aftermarket body and suspension lift kits and oversize tires can be installed to improve step-in height, customize the appearance or enhance the utility of light-duty trucks (“raised vehicles”). The m....
In this study, tests were performed with modified tires at the right rear location on a solid axle sport utility vehicle to compare vehicle inputs and responses from both: (1) staged tire tread belt d....
This paper describes the development of a more accurate shock absorber model in order to obtain better vehicle simulation results. Previous shock models used a single spline to represent shock force v....
Personal mobile vehicles have been extensively studied recently, for the benefit of fuel economy and transportation efficiency. This study proposes a personal vehicle system comprising a new tilting m....
This paper describes an integrated safety concept for Vehicle Dynamics Management (VDM) - the control integration of an electronic stability brake control system (ESC) and with other active chassis sy....
In this work, a theoretical investigation of four-wheel steering (or shortly 4WS) system is presented using a linear model to simulate vehicle handling characteristics. This model incorporates driver'....
It is important to estimate the vehicle state accurately in order to control vehicle behavior. In this study, we used the vehicle sideslip angle as a value indicating vehicle instability. A new method....
In 2004, a model of a 6s6m ABS controller was developed in order to support NHTSA's efforts in the study of heavy truck braking performance. This model was developed using Simulink and interfaced with....
Wheel camber can cause an increase or reduction of the available lateral force during vehicle cornering maneuvers. To reduce undesired wheel cambering, two active control methods were modeled and simu....
In this study, tests were performed to understand the effects of asymmetric longitudinal forces on vehicle response which may be created in certain staged partial tire tread belt detachment tests. In ....
The vehicle body sideslip angle (VBSSA) is a key variable in vehicle dynamics indicating critical driving situations. It is, e.g., essential in vehicle dynamics control concepts. Since it cannot be me....
Real time dynamic simulation of mechanisms with kinematically closed loops requires solving systems of nonlinear differential algebraic equations (DAE). Examples of such mechanisms are racing car susp....
This paper highlighted the up-to-date major efforts and progress on chassis development for a shared platform project. The project history was described briefly. We determined the proper vehicle and c....
This paper discusses the effective utilization of tire force for improving vehicle dynamics. A sensing technology that can detect the tire force based on the transformation of the tire and suspension ....
Motorcycle models in the literature are derived using the Lagrangian formulation approach and are generally complex in order to satisfy the requirement for accuracy of the response. The objective of t....
Active Roll Control (ARC) is one of the most promising active systems to improve vehicle comfort and handling. This paper describes the simulation based procedure adopted to conceive a double-channel ....
A conceptual study of a control strategy that improves vehicle handling during cornering maneuvers while improving vehicle roll stability is presented. From the vehicle rollover propensity estimated b....
A robust controller design method for vehicle roll control with variable speed and actuator delay is presented. Based on a three-degree-of-freedom (3DOF) yaw-roll model, the H∞ performance from the st....
In the first half of this paper describes a new algorithm of an electric power steering system control. The problem of the vehicle with ordinary steering and the reason why it occurs physically are cl....
