“…[4][5][6] The semi-active suspension is extensively used in heavy vehicles given its low cost and simple manufacturing process. Most semi-active suspensions are realized by variable dampers, 7,8 and many control method have been used for the semi-active suspension of heavy vehicles. In 2012, Sulaiman et al 9 studied the semi-active suspension ground-hook (GH) control of heavy vehicles and found that GH control can effectively reduce the dynamic tire load.…”

In order to comprehensively improve the ride comfort performance and the road friendliness performance of the heavy vehicles, an inertial suspension using ground-hook (GH) control is proposed in this paper, and the suspension performances are compared at different loading rates and driving speeds. Firstly, a half vehicle model of the inertial suspension of the heavy vehicle based on the GH control is established. Then, the key parameters of the GH inertial suspension are optimized by the genetic algorithm and the system simulations are carried out. By comparing to the conventional passive suspension, the root-mean-square (RMS) of the vertical acceleration of the body centroid is reduced by 4.87%, and the RMS of the dynamic tire loads of the front and the rear wheels are reduced by 16.19% and 10.02%, respectively. Results show that the GH inertial suspension can effectively coordinate and improve the ride comfort and road friendliness of heavy vehicles simultaneously.

“…Currently, most passenger cars and commercial vehicles in China are equipped with air suspension, ensuring the stability of automobile operation by controlling the airbag pressure of the air springs [1]. Electronically controlled air suspension for vehicle stability control can be achieved through shock absorber damping control [2]. Ding et al [3] proposed the LQR control method of vehicle active suspension based on the adaptive multipopulation genetic algorithm.…”

A damping fuzzy proportional-integral-derivative (PID) control method for electronically controlled air suspension shock absorbers was proposed to reduce the RMS values of the body vibration acceleration and improve vehicle ride comfort. Depending on the operating mode of the electronically controlled air suspension shock absorber, a mechanical model of the air suspension shock absorber was established. A fuzzy PID control technology for damping control of the shock absorber is designed by combining a PID control algorithm with the fuzzy control concept. The adaptive expansion factor of the cybernetics domain for the fuzzy PID controller is calculated by considering nonlinear characteristics and time delay to improve the controller’s adaptability. Then, the control parameters are adjusted based on the control deviation and deviation rate parameters. The nonlinear detection platform produced by an enterprise is selected to build an experimental environment for analysis. Simulation results reveal that when the vehicle speed is 30 m/s, the RMS values of the body vibration acceleration upon applying the proposed method is approximately 0.02 and 0.05 m/s2, respectively, on Class B and C road surfaces. Furthermore, the RMS values of the body vibration acceleration using the proposed method has little fluctuation; when the vehicle speed is 60 m/s, the RMS values of the body vibration acceleration is 0.022 and 0.028 m/s2, respectively, on Class B and C road surfaces, indicating that the proposed method can effectively reduce the RMS values of the body vibration acceleration and improve rider comfort.

“…Therefore, the most important actuator is a variable-damping damper in the semi-active suspension systems. These dampers are classified into electrorheological, magnetorheological and solenoid valve types (Gong and Chen, 2020). In this study, magnetorheological(MR) damper type is modeled.…”

This paper introduces an adaptive semi-active suspension control by considering global positioning system-based and historical road information. The main idea of this study is to find a corresponding trade-off between comfort and stability at different road irregularities. The introduced semi-active controller is designed based on the Linear Parameter-Varying framework. The behavior of the designed controller can be modified by the use of a scheduling variable. This scheduling variable is selected by considering the various road category. TruckSim simulation environment is used in order to validate the introduced adaptive semi-active suspension control system by comparing it with the non-adaptive scenario. The results show that both driving comfort and vehicle stability have been improved with the proposed adaptive semi-active suspension control.
