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 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 a new rollover evaluation index to assess the rollover risk of independently driven heavy-duty vehicles and verifies the feasibility of the improved index through hierarchical control and HIL experiments. The improved LTR index, based on an 18-DOF spatial dynamics model, describes the dynamic change in the tire's vertical load and avoids the problem of directly measuring or estimating the vertical load. Comparisons of three rollover indicators under fishhooking and angle stepping conditions show that the proposed index can more sensitively identify the likelihood of rollover. A hierarchical controller designed based on road surface slip rate identification, ABS control with sliding mode, variable structure, and differential braking effectively predicts and avoids rollover risks.

Summary: This paper presents a rollover index based on minimal sensor signals obtained from an ESC system for detecting and predicting rollovers in various driving situations. By utilizing a simplified dynamic model and reliable measurements, the index is able to reduce parameter uncertainties and accurately estimate rollover risks. The inclusion of road bank angle in the index is crucial for improving rollover detection and mitigation functions of the ESC system.

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 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 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.
