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 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 integrated stability control strategy for tilting vehicles, extending the envelope-based lateral stability controller and utilizing a model predictive controller to address the non-minimum phase problem. The simulation results show that the control effort for maintaining the roll stability of narrow vehicles can be greatly reduced with the envelope-based control scheme. The integrated controller also improves vehicle handling performance while ensuring lateral and roll stability.

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: 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 study aims to enhance the lateral stability of tractors by implementing an active steering system that can convert roll and pitch motion to restore the tractor attitude in potential rollover situations. A sliding mode control algorithm and a lateral stability indicator are used to reduce the risk of tractor rollovers, showing that the proposed control strategy is effective and robust.

Summary: The narrow tilting vehicle has gained extensive public attention due to traffic congestion and environmental pollution. The active rolling motion control reduces the rollover risk caused by the vehicle's structure size. Drift motion control, which makes full use of the vehicle's dynamic performance and improves driving safety especially when tires reach their limits, reflects the latest research in regular-size vehicles.

Summary: This paper presents an integrated controller for an autonomous articulated electric vehicle (AAEV) to improve path tracking and prevent rollover. The AAEV, which has an articulated frame steering (AFS) mechanism, is susceptible to rollover due to its lack of front wheel steering and high height-to-track width ratio. The proposed controller aims to achieve path following and manage velocity to enhance the safety of the AAEV. A kinematic model with actuation delay is used to model the vehicle behavior, and a local linearization approach is employed to improve accuracy and reduce computation load. A model predictive control (MPC)-based reference state tracker is designed to optimize articulation angle rate and longitudinal acceleration commands. Simulation results demonstrate that the proposed algorithm reduces path tracking error and load-transfer ratio.

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: A rollover test bench was designed, manufactured, and validated for analyzing ATV-Quad overturn in different configurations. The main purpose was to determine the tilt angle triggering the overturn and the effectiveness of the AD-ROPS system in protecting drivers. Multiple tests were conducted with various ATV-Quads in different configurations on the newly developed bench.
