Abstract
Yaw stability control system plays a significant role in vehicle lateral dynamics in order to improve the vehicle handling and stability performances. However, not many researches have been focused on the transient performances improvement of vehicle yaw rate and sideslip tracking control. This paper reviews the vital elements for control system design of an active yaw stability control system; the vehicle dynamic models, control objectives, active chassis control, and control strategies with the focus on identifying suitable criteria for improved transient performances. Each element is discussed and compared in terms of their underlying theory, strengths, weaknesses, and applicability. Based on this, we conclude that the sliding mode control with nonlinear sliding surface based on composite nonlinear feedback is a potential control strategy for improving the transient performances of yaw rate and sideslip tracking control.
Highlights
In vehicle dynamic control of road-vehicle, controlling the lateral dynamic motion is very important where it will determine the stability of the vehicle
This paper has extensively reviewed the elements of yaw stability control system
In designing yaw stability controller, all these elements, that is, vehicle models, control objectives, active chassis control, and control strategies, play an important role that contributes to the control system performances
Summary
In vehicle dynamic control of road-vehicle, controlling the lateral dynamic motion is very important where it will determine the stability of the vehicle. The elements of yaw stability control system, that is, vehicle dynamic models, control objectives, active chassis control, and its control strategies as depicted, are extensively reviewed. To achieve the control objectives, it is essential to control the variables of yaw rate and sideslip angle in order to ensure the vehicle stable. An appropriate robust control strategy should be proposed to improve the transient performances of the yaw rate and sideslip tracking control in the presence of uncertainties and disturbances. As a finding from the reviews, this paper briefly discussed a possible high performance robust tracking control strategy that can be implemented for yaw stability control system.
