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 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: Narrow electric three-wheelers are a potential solution to traffic congestion and parking issues, but have poor maneuverability at high speeds. Researchers have proposed the concept of active tilt control to reduce tilting, with the steering direct tilt control system showing potential to control tilting and optimize tilt angle based on the rollover index.

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 study proposes a real-time motor control strategy to improve the anti-rollover stability of electric vehicles, based on the acquisition of vehicle attitude data and real-time monitoring of the vehicle's operating state. The lateral load transfer rate is used as the evaluation index for vehicle rollover, and the motor speed is actively controlled to avoid or reduce the risk of rollover when the real-time rollover indicator exceeds the safety threshold.

Summary: In order to mitigate the impact of unreasonable road alignment design on vehicle driving safety, this study conducted research on road alignment optimization and vehicle driving safety based on two-dimensional point collision dynamics. Through a two-dimensional point collision dynamics model, the relationship between kinematic parameters before and after vehicle collision was deduced. By analyzing the vehicle-road coupling dynamics model after collision, a safety threshold between the radius of the circular curve and the road superelevation was derived, with vehicle rollover as the critical condition. Subsequently, an optimization scheme for road alignment based on vehicle rollover stability after collision was proposed. Finally, the rationality of the optimization scheme was verified through PC-Crash simulation, demonstrating that the proposed scheme meets the safety requirements for vehicle rollover. This study optimizes the relevant indicators of road alignment while ensuring vehicle rollover stability, providing a reference for improving and optimizing road alignment design. It also has significant guiding implications for the formulation of vehicle driving safety management measures.
