Vehicle system dynamics and integrated control is a new subject that has emerged in recent years, and is a research hotspot in the field of vehicle engineering internationally. Over the past two decades, vehicle system dynamics and integrated control technologies have developed a relatively complete theoretical and technical foundation with the drive of various applications and techniques in relative fields. At present, this technology is leading towards the integration of dynamic system modeling, simulation, analysis, and control. The previous chapters of this book respectively describe the background on the modeling of vehicle system dynamics, tyre dynamics, full vehicle dynamics, longitudinal/lateral/vertical vehicle dynamics and control, centralized integrated control, and layered coordinated control. However, vehicles are complicated multivariable nonlinear dynamic systems, developed with an increasingly higher demand for their performance. Hence, when a complete analysis and integrated control to improve the overall vehicle performance is conducted, there are many key technical problems that require further in-depth studies.
9.1 Models of Full Vehicle Dynamics
Under the influence of complex operating conditions and various uncertain factors (due to the uncertainty of the environment and inaccuracy of design factors), the tyre load, road adhesion condition, and vertical/lateral/tangential forces change during vehicle travel. The uncertainty included in ...
