Automated Vehicle Stability Control for Articulated Vehicles
نویسندگان
چکیده
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 vehicles in adverse road conditions.

Enhancement of Articulated Heavy Vehicle Stability by Optimal Linear Quadratic Regulator (LQR) Controller of Roll-yaw Dynamics
Non-linear characteristic of tire forces is the main cause of vehicle lateral dynamics instability, while direct yaw moment control is an effective method to recover the vehicle stability. In this paper, an optimal linear quadratic regulator (LQR) controller for roll-yaw dynamics to articulated heavy vehicles is developed. For this purpose, the equations of motion obtained by the MATLAB sof...
متن کاملOptimized Braking Force Distribution during a Braking-in-Turn Maneuver for Articulated Vehicles
Improvement in braking performance and vehicle stability can be achieved through the use of braking systems whose brake force distribution is variable. Electronic braking force distribution has an important and serious role in the vehicle stopping distance and stability. In this paper a new approach will be presented to achieve the braking force distribution strategy for articulated vehicles. F...
متن کاملDynamic Analysis and Stability of Articulated Liquid Cargo Vehicles with Tank Baffles
Articulated liquid cargo vehicles transporting inflammable fuels and dangerous chemical products require special consideration when traveling on urban roads or cruising at highway speeds. The road safety and handling of these kinds of vehicles may be adversely affected when negotiating sharp turns or travelling on slippery roads, which may result in either lateral instabilities or complete roll...

متن کاملAnalysis of Roll Control System to Eliminate Liquid Sloshing Effect on Lateral Stability of an Articulated Vehicle Carrying Liquid
In this paper, the consequences of filled volume on the transient lateral dynamic and stabilities boundaries displacement of an articulated vehicle carrying liquid is investigated. First, a sixteen-degrees-of-freedom nonlinear dynamic model of an articulated vehicle is developed then, using TruckSim software the model is validated. Next, the dynamic interaction of the fluid cargo with the vehic...
