Summary: This study investigated the impact of introducing a CAV-loading system to a roll-on, roll-off (RORO) port. The results revealed that using the CAV-loading system reduced operating costs by 90% and significantly improved terminal operations. Additionally, the use of the CAV-loading system resulted in a 12% reduction in CO2 emissions compared to the current loading system. This study has important implications for incorporating autonomous vehicles in planned automobile terminal operations.

Summary: The model and analysis results in the paper are applicable to dynamic analyses of autonomous driving control and design of articulated steering vehicles. Articulated steering vehicles, widely used in mining, construction, agriculture, and forestry, have complex dynamic characteristics that currently lack reliable models for further research. This study established a simulation platform and validated the dynamic model with field test data. The distribution of hydraulic and drive power and the influence of dynamic parameters on motion were also analyzed.

Summary: Connected vehicle (CV) technologies are transforming traditional traffic models, with the proposal of bidirectional vehicle information structure (BDVIS) and derived multiple vehicles information structure (DMVIS) to enhance car-following models using acceleration information of preceding and following vehicles. Both BDVIS and DMVIS demonstrate better performance in improving traffic flow stability compared to the original car-following model, and provide advantages for differently positioned vehicles within a platoon.

Summary: The issue of maintaining roll stability for liquid tank semi-trailers during turning or emergency voidance has not been effectively solved. The current method of evaluating roll stability using lateral acceleration or vehicle attitude has limitations. This paper proposes a method to analyze roll stability using vertical wheel force, which is validated through experiments in real driving conditions.

Summary: Collision risk modeling with multiple surrounding target vehicles is necessary for host vehicle trajectory planning. A twisted Gaussian risk model is proposed to accurately describe the lateral behaviors of target vehicles. By considering both longitudinal and lateral motion states, the proposed model allows for simultaneous consideration of target vehicle behaviors in collision risk modeling. Simulation and experimental results demonstrate that considering the longitudinal-lateral motion states of target vehicles enables the host vehicle to operate more safely and efficiently.

Summary: This study proposes a comprehensive vehicle dynamics model to describe the dynamics performance of a vehicle after a tire blow-out, and presents an integrated control framework for combined yaw plane and roll-plane stability control. The control framework includes a vehicle state predictor, an upper-level control mode supervisor, and a lower-level 14-DOF model predictive controller. Simulation tests are conducted to verify the effectiveness of the proposed control strategy.

Summary: This paper explores the impact of active suspension systems on the comfort and handling of passenger cars, and discusses the tuning methods for the nonlinearity of the anti-roll moment distribution. By analyzing the effect of lateral load transfer on lateral axle force and cornering stiffness, a linearized axle force formulation is proposed and the controllers are optimized. The importance of using accurate models of lateral load transfer in control design is demonstrated through simulation results from a nonlinear vehicle model.

Summary: The dynamic performance of the trailer bogie brake system is crucial for the safe operation of a high-speed train during braking. This study developed a novel ten-degree-of-freedom (10-DOF) dynamics model for the trailer bogie brake system, considering non-linear factors such as disc-pad friction and wheel-rail interactions. Field test results and numerical simulations based on the model showed that more intense vibrations occur at low vehicle speeds, resulting from the limit cycle oscillation of the brake unit and causing system instability. The study further investigated the equilibrium points, linear stability, and non-linear vibration response under different braking conditions and suspension parameters, with the results indicating that specific suspension stiffness and damping can improve system stability.

Summary: The article introduces an active linear quadratic regulator (LQR) multi-axle-steering method to improve the maneuverability and stability of a heavy articulated vehicle. It builds a linear yaw-plane model and a reference model to track the desired state responses. An LQR controller is proposed based on the linear vehicle model to make the control variables follow the desired state responses. The effectiveness of the method is validated through simulations.
