“…The rotary hydraulic pump was applied to the vehicle ASB, and the corresponding feedforward and feedback controllers were designed. The vehicle simulation and bench test were carried out, but the technical parameters of the hydraulic pump were not analyzed [4]. Rollover is a serious problem for the safety of heavy-duty vehicles, which can cause huge economic and environmental consequences.…”

Due to the fixed geometric parameters and structure of vehicle passive stabilizer bar, the corresponding anti-roll moment cannot be provided in real time according to the state of the vehicle body, limiting the improvement of the anti-roll performance of vehicles. In order to improve the anti-roll performance of vehicles, a vehicle roll model, a wheel load transfer model and a finite element calculation model of switched reluctance motor were established respectively in this study. By calculating the vehicle roll and wheel load transfer model, the target anti-roll moment of the active stabilizer bar driven by the switched reluctance motor was obtained to determine the moment requirement of the designed switched reluctance motor, and the finite element method was used to design the corresponding motor. Based on the co-simulation platform of carsim and MATLAB/Simulink, it was verified that the designed active stabilizer bar system driven by the switched reluctance motor can improve the anti-roll performance of vehicles. The results demonstrate that under the condition of double lane change, the active stabilizer bar driven by the switched reluctance motor has a vehicle roll angle range of-1.2~1.2°, and the passive stabilizer bar has a roll angle range of-2.5~4.7°. Compared with the passive stabilizer bar, the anti-roll performance of active stabilizer bar driven by the switched reluctance motor is improved by about 50%. The proposed method provides a good prospect for optimizing the design of vehicle active stabilizer bar system.

This paper presents a novel active roll control algorithm for vehicle hydraulic active stabilizer bar system. The mechanical structure and control scheme of hydraulic active stabilizer bar system is detailed. The anti-roll torque controller is designed with “Proportional-Integral-Differential (PID) + feedforward” algorithm to calculate the total anti-roll torque. A lateral acceleration gain and roll rate damping are added into “PID + feedforward” controller, which can improve vehicle roll dynamic response. The torque distributor is introduced based on fuzzy–PID algorithm to distribute the anti-roll torque of front and rear stabilizer bar dynamically, which can improve vehicle yaw dynamics response. The actuator controller is used for realizing the closed-loop control of the actuators displacement and generating the accurate anti-roll torque. The hardware-in-the-loop simulation platform is established based on AutoBox and active stabilizer bar actuators. The hardware-in-the-loop experiment is carried out under typical maneuvers. Experimental results show that the proposed control algorithm improves the vehicle roll and yaw dynamics response, which can enhance the vehicle roll stability, yaw stability, and ride comfort.

This paper describes a novel hierarchical control algorithm for the electric active stabilizer bar (ASB) system, which is applied to a four-wheeled road vehicle. The proposed control algorithm is designed to improve vehicle roll and yaw dynamics. The upper-level controller calculates the target active anti-roll torque via sliding mode control, which is aimed at improving the roll stability. The middle-level controller distributes active anti-roll torque between front and rear axle via fuzzy control, which can improve the handling stability through changing lateral load transfer of front and rear axles in real time. The lower level controller is employed to control the output torque of ASB actuators via PI control and improve the output characteristic of actuators with excellent response and stability. The numerical simulation and hardware-in-the-loop (HIL) experiment are carried out to evaluate the performance of the proposed control algorithm. It is demonstrated that the ASB system based on proposed control algorithm makes a significant improvement in the vehicle roll stability, ride comfort and handling stability.
