This paper presents the modelling and simulation of a stable angle-based instability threat indicator for articulated off-road vehicles. First, a stable angle is represented by the vertical forces of four wheels and steering angle of an off-road articulated steer vehicle. Then a vehicle prototype model is built based on a specific wheel loader type and a tyre/terrain model. Finally, the prototy...

The articulated dump truck is a widespread transport vehicle for narrow rough terrain environment. To achieve the autonomous driving in the underground tunnel, this article proposes a path following strategy -for articulated vehicle based on feedback linearization algorithm. First of all, the kinematic model of articulated vehicle, which reflects the relationship between the structure parameter...

The aim of this article is to analyze the effect of kinematic parameters on a novel proposed on–line motion planning algorithm for an articulated vehicle based on Model Predictive Control. The kinematic parameters that are going to be investigated are the vehicle’s velocity, the maximum allowable change in the articulated steering angle, the safety distance from the obstacles and the total numb...

The Articulated Wheeled Vehicle (AWV) paradigm examines a class of wheeled vehicles where the chassis is connected via articulated chains to a set of ground-contact wheels. Activelyor passivelycontrolled articulations can help alter wheel placement with respect to chassis during locomotion, endowing the vehicle with significant reconfigurability and redundancy. The ensuing ‘leg-wheeled’ systems...

This work investigates the dynamics of heavy articulated vehicles and the problem of yawinstability caused by loss of traction. A mathematical model of the system is derived and applied to a typical vehicle used in mine haulage applications. Automatic control, based on differential wheel braking, is explored by simulation and shown to be potentially valuable in improving the safety of such vehi...

The stability analysis of articulated frame steer vehicle models is presented. To reveal the relationship between the “oversteer” and “jack-knife” motion modes based on a 2 degree of freedom (DOF) and 3 DOF vehicle models, respectively, the results derived from these models are investigated and compared. To identify the effects of design variables on the lateral stability of the vehicle, a more...
