Adaptive suspension control considering passenger comfort and stability of the vehicle has been researched intensively, thus several automotive companies already apply these technologies in their high-end models. Most of these systems react to the instantaneous effects of road irregularities, however, some expensive camera-based systems adapting the suspension in coherence with upcoming road conditions have already been introduced. Thereby, using oncoming road information the performance of adaptive suspension systems can be enhanced significantly. The emerging technology of cloud computing enables several promising features for road vehicles, one of which may be the implementation of an adaptive semi-active suspension system using historic road information gathered in the cloud database. The main novelty of the paper is the developed semi-active suspension control method in which Vehicle-to-Cloud-to-Vehicle technology serves as the basis for the road adaptation capabilities of the suspension system. The semi-active suspension control is founded on the Linear Parameter-Varying framework. The operation of the presented system is validated by a real data simulation in TruckSim simulation environment.

Several types of dampers are used in the suspension systems of road vehicles, while the magneto-rheological damper is one of the most efficient solutions to manage the balance between objectives of vehicle suspension control. Various types of failures may occur in magneto-rheological dampers, and these faults may affect adversely the operation of the vehicle suspension system. This paper is concerned with the design of semi-active suspension control with fault-tolerant control reconfiguration through the Linear Parameter-Varying control method. In case of a damper oil leakage affecting the damper force, the proposed control strategy calculates feasible damper forces for the healthy dampers in order to compensate for the lost force of the faulty damper. Unlike other approaches in the literature, this method aims to enhance performances by modifying the force of a healthy damper to the same level as the force of a faulty damper. The simulation has been performed in the TruckSim environment to demonstrate the operation of the proposed fault-tolerant control strategy. The results show that the introduced novel reconfiguration control method improved driving comfort, road holding and vehicle stability.

“…For instance, the damper needs to act differently for each road irregularities, such as bumps, potholes, roughness, etc. Thus, the semi-active suspension control is founded on the Linear Parameter-Varying (LPV) framework in this study due to its availability for the dynamic configuration by modifying the scheduling variable, see (Basargan et al, 2020a;Basargan et al, 2020b;Basargan et al, 2021;Morato et al, 2019;Pham, 2020). LPV control method describes an approach for the semi-active suspension controller with consideration of actuator constraints.…”

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.
