Improving the Stability of Semi Trailer Articulated Vehicles

The transportation of industrial products is an important function of every industry involved in mass production. This is mostly done with the use of semi trailer articulated vehicles. The dynamics characteristic of these vehicles differs from those of other vehicles, and their accidents are fatal and destructive leading to lost of lives and valuable properties. Therefore, there is a need for continuous research and improvement of the stability of these vehicles. This paper aimed at reviewing literatures on improvement of stability of this vehicle in order to ensure safety of lives and properties. Driver Assistance Systems (DAS) such as Semitrailer Differential Braking Technique (SDBT), Roll Stability Control (RSC) system, Electronic Stability Control (ESC) system, Active Yaw Control (AYC) system, Linear Quadratic Regulator (LQR) controller, Robust LQR (RLQR), were noted as an efficient method for combating the vehicle instability and loss of control. It was noted that the RWA is an important parameter for determining the rollover propensity of this vehicle., while a driver model would be of great important to investigate the interaction between the driver and Driver Assistance Systems (DAS).
