Summary: This paper proposes an integrated control framework of torque vectoring and active front-wheel steering system to ensure the vehicle lateral motion stability. The system uncertainties are dealt with using the polytope method with finite vertices, and a distributed model predictive control is adopted to construct a dynamic interactive model between agents. Through introducing the game theory, a distributed parallel control scheme is developed to obtain the cooperative strategy of agents. The proposed control scheme is validated through hardware-in-the-loop tests.

Summary: In this article, a robust nonlinear torque control method for electric power steering (EPS) systems is proposed, using the steering wheel torque (SWT) model. The method utilizes an extended state observer to estimate disturbances and a nonlinear sliding mode control (SMC) to track the desired SWT and reduce estimation error. Experimental validation is performed using a pinion type EPS hardware-in-the-loop simulation.

Summary: This article discusses the issue of vehicle roll instability when steering at high speeds. It recommends installing an active stabilizer bar in the car to prevent rolling over and improve stability. A complex dynamic model is used to evaluate and analyze vehicle oscillations, and a fuzzy algorithm with three independent inputs is used to control the operation of the active stabilizer bar. Numerical simulation in a Simulink environment shows that the new algorithm significantly reduces the risk of rollover and improves the car's stability and safety.

Summary: In order to improve the rollover stability of heavy dump trucks during lifting and unloading, a sliding mode-robust control method based on anti-rollover early warning was proposed. The model of the heavy dump truck lifting and unloading roll dynamics was established and verified through simulation. The controller was designed by combining sliding mode control and active suspension control. The proposed method showed better anti-rollover capability and stability compared to conventional methods.
