Instability of vehicle can be defined as an unexpected response maneuver that induces disturbance, occurring in the ground plane. This include longitudinal, lateral, pitch, yaw, roll direction, or their combinations. Many tractor semitrailer accidents caused by lateral instabilities which may classified into two types: rollover and yaw instability. Rollover occurs when centrifugal forces impose...

Rollover incidents while driving their military vehicles has resulted in,soldiers incurring injuries or even losing their lives. A recent report identified that one cause of vehicle rollovers is the driver's inability to assess rollover threat, such as a cliff, soft ground, water, or culvert on the passenger side of the vehicle. The vehicle's width hinders the driver's field of view. To reduce ...

Robust control design of vehicles addresses the effect of uncertainties on the vehicle’s performance. In present study, the robust optimal multi-objective controller design on a non-linear full vehicle dynamic model with 8-degrees of freedom having parameter with probabilistic uncertainty considering two simultaneous conflicting objective functions has been made to prevent the rollover. The obj...

The rollover evaluation index provides an important threshold basis for the anti-rollover control system of vehicle. Regarding risk independently driven heavy-duty vehicles, a new is proposed, and feasibility improved was verified through hierarchical HIL (hardware-in-the-loop) experiments. Based on 18-DOF spatial dynamics model vehicle, LTR (load transfer rate) obtained to describe dynamic cha...

In order to reduce the influence of unreasonable road alignment design on vehicle driving safety, a study optimization and safety based two-dimensional point collision dynamics was carried out. First, through model, relationship kinematic parameters before after deduced. Second, according vehicle–road coupling dynamic model analysis collision, threshold between radius circular curve superelevat...
