Abstract: Some applications of Articulated Steer Vehicles (ASVs) result in instability problems, such as rollover, jackknifing and snaking. To find the direction of future investigations and developments for enhancing their stability, the lack of research in this area must be identified. In this work, for ASVs, the published literature on stability, proposed early warning devices as well as stability control systems is reviewed. The literature survey shows that the previous work on the subject of stability analysis and control of ASVs is limited and mainly concerned with the snaking instability. Therefore, more work is needed in predicting and preventing rollover and jackknifing.

Keywords: ASV; articulated steer vehicles; stability control; snaking; jackknifing; rollover; early warning devices; stability analysis; instability.
