Summary: This paper proposes an MPC-based control strategy to prevent vehicle rollover during high-speed driving. By considering tire force saturation and real-time rollover index, the control region is divided into different stability regions. State constraints are set based on driver behavior and road conditions to improve overall vehicle performance.

Summary: This study proposes an improved dynamic rollover index (RI) that can detect real-time rollover events in heavy-duty vehicles. By designing an unknown input observer (UIO) to estimate the vehicle's roll angle and using a parameter estimation algorithm to observe unmeasurable and time-varying parameters, the proposed method shows accurate estimation of key parameters and strict rollover detection. Furthermore, a dynamic predictive rollover threshold is determined by investigating the thresholds of roll angle and lateral acceleration, ensuring sufficient response time for controller delay.

Summary: This paper presents a computationally efficient chance-constrained rollover-free motion planning method for reconfigurable vehicles with limited accuracy 3-D terrain models. The method formulates the motion planning problem as a nonlinear optimal control problem, utilizing a constraint on the probability of rollover. By deriving a geometric interpretation of the chance constraint based on SO(3), the computational efficiency is increased. Monte Carlo simulations and experimental data validation demonstrate the usefulness and performance of the proposed method.

Summary: This paper uses spatial dynamics model and nonlinear double-track dynamics model to simulate vehicle oscillations, and fuzzy control algorithm is used to control the active stabilizer bar. The simulation results show that the use of active stabilizer bar controlled by fuzzy algorithm can significantly reduce the roll angle of the vehicle body and the change in vertical force at the wheel, thus improving the rollover phenomenon of the vehicle.

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: This work addresses the cooperative trajectory-planning problem in a double lane change scenario for autonomous driving using distributed model predictive control. Two frameworks are developed to solve this problem: one approach introduces a collision cost function to achieve smooth and bounded collision functions, while the second method uses a hierarchical scheme with trajectory-planning and tracking controller units. Tests and evaluations are conducted using matlab-carsim co-simulation to compare the approaches for cooperative double lane change maneuver in a three-lane road with obstacles.

Summary: The multi-UAV path planning method based on artificial potential field (APF) has advantages of rapid processing speed and ability to handle dynamic obstacles. However, it lacks consideration of the initial heading constraint of UAVs, resulting in local minimum traps and insufficiently smooth paths. This paper proposes a fixed-wing UAV formation path planning method based on piecewise potential field (PPF) to address these issues. Simulation experiments show that the PPF-based method considers the initial heading limits of UAVs, resulting in considerably smoother paths and the ability to plan multiple UAV tracks without conflicts in complex scenarios.

Summary: This paper studies a collision avoidance control algorithm for unmanned surface vehicle (USV) with COLREGs. A real-time collision avoidance control algorithm based on dynamic constraints is proposed according to the principle of dynamic window approach (DWA), which includes the design of candidate control behavior space, feasible trajectory prediction, collision risk assessment, and acquisition of optimal control quantities. The algorithm meets the constraints of actuator, avoids the problem of velocity window parameters estimation in DWA, and ensures compliance with the COLREGs by introducing the collision avoidance rule function.
