“…The system structure of sliding-mode variable-structure control can be continuously adjusted and optimized according to the current state of the system. As the sliding mode of the sliding-mode variable-structure controller can be set artificially and has nothing to do with the parameters of the control object, it has the advantage of strong adaptability [53,54]; at the same time, the sliding mode in a sliding-mode variable structure can be set artificially, which is independent of the control object and has the advantage of responding fast. Based on the characteristics of the above sliding-mode variable-structure control, the algorithm can be applied to the anti-rollover control of heavy vehicles.…”

The rollover evaluation index provides an important threshold basis for the anti-rollover control system of vehicle. Regarding the rollover risk of independently driven heavy-duty vehicles, a new rollover evaluation index is proposed, and the feasibility of the improved index was verified through hierarchical control and HIL (hardware-in-the-loop) experiments. Based on an 18-DOF spatial dynamics model of a heavy-duty vehicle, the improved LTR (load transfer rate) index was obtained to describe the dynamic change in the tire’s vertical load. It replaces the suspension force and the vertical inertia force of the unsprung load mass. It avoids the problem of directly measuring or estimating the vertical load in the LTR index. Under the conditions of fishhooking and angle stepping, three types of rollover indicators were compared, and the proposed index can more sensitively identify the likelihood of rollover. In order to apply the improved rollover index to a rollover control well, a hierarchical controller based on the identification of the slip rate of the road surface, ABS control with sliding mode, variable structure and differential braking was designed. Simulations and HIL tests proved that the designed controller can accurately predict the rollover risk and avoid the rollover in time. Under the condition of J-turning, the yaw rate, slip angle and maximum lateral acceleration are reduced by 9%, 16% and 3%, respectively; under the condition of fishhooking, the maximum yaw rate, slip angle and lateral acceleration are reduced by 12%, 18% and 3%, respectively.

The ride comfort is controlled by the suspension system. In this article, an active suspension system is used to control vehicle vibration. Vehicle oscillations are simulated by a quarter-dynamic model with five state variables. This model includes the influence of the hydraulic actuator in the form of linear differential equations. This is a completely novel model. Besides, the OSMC algorithm is proposed to control the operation of the active suspension system. The controller parameters are optimized by the in-loop algorithm. According to the results of the study, under normal oscillation situations, the maximum and average values of the sprung mass were significantly reduced when the OSMC algorithm was applied. In dangerous situations, the wheel is completely separated from the road surface if the vehicle uses only the passive suspension system or active suspension system with a conventional linear control algorithm. In contrast, the interaction between the wheel and the road surface is always guaranteed when the OSMC algorithm is used to control the operation of the active suspension system. The efficiency that this algorithm brings is very high.

“…Some studies focus on optimizing the vehicle suspension system to improve handling, vehicle manoeuvrability, rollover probability and passenger comfort. [19][20][21] Other work proposes to improve traditional suspension systems by using composite materials in the design process, 22 or to substitute the mechanical system with a mechatronic system to better isolate vibrations. 23 In the case of an optimization problem based on a finite element model, the substitution models are privileged to estimate the objective function.…”

Improvised Explosive Devices (IEDs) represent a serious threat to vehicles. These IEDs can partially or fully damage the vehicle and the onboard equipment and, threaten the lives of its crew. To protect against these devices, modifications to specialized vehicles are made in different parts. Among these latter, the present work focuses on the effects of the suspension system on the dynamic response of the vehicle. The behaviour of a McPherson suspension system of a light vehicle is numerically studied in order to optimize the dimensions of selected components. Three models based on different approaches are developed. The first is based on an Arbitrary Lagrangian Eulerian (ALE) formulation with fluid-structure coupling, which gives a more realistic representation of the blast phenomena. However, it needs significant calculation time and computational power. The second is a simplified, purely Lagrangian, model which requires less computational resources but includes several assumptions. The third model is based on a meta-modelling approach. This latter is used to optimize the dimensions of selected sub-systems of the vehicle suspension via a genetic optimization algorithm.
