“…With the above simplifications [12], the displacement of the trunk at the left and right wheels when the vehicle is turning can be determined by the following formula: In there: F z s : Vertical load acting on the airbag(N). F z s(0) : Vertical load in static state (N).…”

This article deals with the problem of controlling the stiffness of the air suspension system to help stabilize the body when the vehicle is moving around. Through the simulation of the change of the suspension stiffness parameter using Matlab simulink software, this paper has shown the impact of external force on the change of air suspension stiffness through simulation graphs. Based on the specifications of the Thaco Mobihome vehicle, simulation results have shown that there is a control to change the air suspension stiffness to help the vehicle move more stably and safely in the horizontal direction when the vehicle is moving around. From the results of this study, it has also been shown that the application of air suspension system for passenger cars will completely improve the level of stability and safety for passengers.

In this study, a cooperative control method based on model predictive control and multiagent theory is proposed to control an interconnected air suspension system with three controllable structures of interconnection mode, damping, and vehicle height. The model predictive controller is constructed based on a discrete-time state-space model. The optimal interval for suspension force is obtained through solving cost functions while satisfying a set of constraints on controlled variables and thereby reducing the coupling complexity of a multivariable control system. Deliberative agents are involved in building cost functions of interconnection mode, vehicle height adjustment, and damping force, and the energy consumption control strategy is established to realize suspension force distribution with low energy consumption. Finally, the test results show that the proposed control method can significantly improve vehicle ride comfort and restrain rollover on the premise of ensuring energy efficiency. Compared with traditional control, the peak value of the sprung mass acceleration speed decreases by 70% and the peak value of the unsprung mass acceleration speed decreases by 75% under straight-driving condition. The roll angle decreases by 40% under the steering condition. As for the traditional control, they are skyhook, imitation skyhook, and PID-PWM control strategies.

“…Holford, P. Surwattanawan [20] is insightful as it deals with the issues of active suspension modeling and employs a real-life quartercar model described in the article. Other articles deal with active suspension control problems [21][22][23][24] or analyze the performance of specific suspensions [25][26][27]. Some research investigates the active suspension anticipation function.…”

Investigation of Vehicle Stability with Consideration of Suspension Performance

The issue of movement stability remains highly relevant considering increasing vehicle speeds. The evaluation of vehicle stability parameters and the modeling of specific movement modes is a complex task, as no universal evaluation criteria have been established. The main task in modeling car stability is an integrated assessment of the vehicle’s road interactions and identification of relationships. The main system affecting the vehicle’s road interaction is the suspension of the vehicle. Vehicle suspension is required to provide constant wheel to road surface contact, thus creating the preconditions for stability of vehicle movement. At the same time, it must provide the maximum possible body insulation against the effect of unevennesses on the road surface. Combining the two marginal prerequisites is challenging, and the issue has not been definitively solved to this day. Inaccurate alignment of the suspension and damping characteristics of the vehicle suspension impairs the stability of the vehicle, and passengers feel discomfort due to increased vibrations of the vehicle body. As a result, the driving speed is artificially restricted, the durability of the vehicle body is reduced, and the transported cargo is affected. In the study, analytical computational and experimental research methods were used. Specialized vehicle-road interaction assessment programs were developed for theoretical investigation. The methodology developed for assessing vehicle movement stability may be used for the following purposes: design and improvement of vehicle suspension and other mechanisms that determine vehicle stability; analysis of road spans assigned with characteristic vehicle movement settings; road accident situation analysis; design of road structures and establishment of certain operational restrictions on the road structures. A vehicle suspension test bench that included original structure mechanisms that simulate the effect of the road surface was designed and manufactured to test the results of theoretical calculations describing the work of the vehicle suspension and to study various suspension parameters. Experimental investigations were carried out by examining the vibrations of vehicle suspension elements caused by unevenness on the road surface.
