“…[36,66]. Cooperrider et al [67] conclude that the lateral acceleration required to induce rollover is a function of the time duration of its application. When the lateral acceleration exceeds the static rollover limit, it needs to be sustained for only a very limited time period to cause rollover.…”

This paper provides an overview of the latest advances in road vehicle suspension design, dynamics, and control, together with the authors' perspectives, in the context of vehicle ride, handling and stability. The general aspects of road vehicle suspension dynamics and design are discussed, followed by descriptions of road roughness excitations with a particular emphasis on road potholes. Passive suspension system designs and their effects on road vehicle dynamics and stability are presented in terms of in-plane and full-vehicle arrangements. Controlled suspensions are also reviewed and discussed. The paper concludes with some potential research topics, in particular those associated with development of hybrid and electric vehicles.

“…Review of literature [1][2][3][4][5][6][7][8][9], various stability control system testing methods has been discussed. But each has its constraints SIL provide less accurate results, HIL and physical testing are costlier & time consuming and needs some kind of validation to finalize the outcome.…”

This Study was performed during the winter of 2014 at Revi Winter Track in Arjeplog, Sweden on Snow & Ice. The thesis describes how to optimize the intervention of an Vehicle Dynamic Control (VDC) system for a sports car. The problem with VDC today is that it is very often defensively programmed and affects the feel when the car is driven, the intervention of VDC in this case is known as unwanted VDC intervention. What to be researched in this thesis is if an optimization of the program can be done that allows greater body slip without affecting the vehicle dynamics and stability in a negative way. Stability control system (SCS) simulation method which is the combination of virtual plus physical world is most suitable for testing and optimization of active stability control systems like VDC. Optimization and tuning procedure for mitigating the unwanted intervention of the control system during handling manoeuvre test has been achieved through SCS simulation. Field test procedures and results for SUV are described. The field test results are used to validate a simulation model which is then analyzed under severe maneuvering conditions to shed light on dynamic stability issues.

“…Following are several examples of tripping mechanisms that can initiate a rollover: (1) interaction between a tire or wheel rim and pavement [6], (2) wheels furrowing into soil or sod [7,8], and (3) wheels impacting a curb [7,9]. For each of these mechanisms, the magnitude and duration of the tripping force and the manner in which that force is applied through time will vary.…”

This paper explores the dynamics of rollover crashes and examines factors that influence the severity of the roof-to-ground impacts that occur during these crashes. The paper first reports analysis of 12 real-world rollover accidents that were captured on video. Roll rate time histories for the vehicles in these accidents are reported and the characteristics of these curves are analyzed. Next, the paper uses analytical modeling to explore the influence that the trip phase characteristics may have on the severity of roof-to-ground impacts that occur during the roll phase. Finally, the principle of impulse and momentum is used to derive an analytical impact model for examining the mechanics of a roof-to-ground impact. This modeling is used to identify the influence of various impact conditions on the severity of a roof-to-ground impact.
