“…The simulated results show the trend according to our results. The improvements were found to be 6%, 15% and 25% by Sulaiman et al [39], Poussot-Vasal et al [34], and Yerrawar et al [40], respectively. Nevertheless, again the evaluation of those results was completely different, and a comparison with those results is not straightforward too.…”

The car suspension setting is always a trade-off between comfort and handling. The semi-active damper system seems to be an option for reducing the compromise between the two demands. This paper deals with the effect of the magnetorheological damper setting on a car’s suspension performance, especially tire grip, which was directly measured. A unique test rig was developed, and an experimental trolley with a fast magnetorheological damper (response time of 3 µs) was used in the paper. The damper was controlled by a modified Groundhook algorithm. Compared with the passive regime, the experiments showed a 30% improvement when using the Groundhook algorithm and when the damper was adequately set. The experiments proved the trends that were set by simulations.

“…Active suspension systems are expensive in terms of cost and energy consumption and provide an active damping force that is generated by using an external power device in response to data from displacement and acceleration sensors installed in the vehicle body. Passive suspension systems provide poor performance in terms of road handling and ride comfort and are composed of passive dampers and conventional springs installed between the wheel axle assembly and the vehicle body [1][2][3][4]. Semi-active suspension systems are economic in terms of cost and energy consumption and provide good suspension performance by using controllable semi-active dampers [5][6][7][8].…”

Hybrid Sliding Mode Control of Full-Car Semi-Active Suspension Systems

et al. 2021

With the advance in technology in driving vehicles, there is currently more emphasis on developing advanced control systems for better road handling stability and ride comfort. However, one of the challenging problems in the design and implementation of intelligent suspension systems is that there is currently no solution supporting the export of generic suspension models and control components for integration into embedded Electronic Control Units (ECUs). This significantly limits the usage of embedded suspension components in automotive production code software as it requires very high efforts in implementation, manual testing, and fulfilling coding requirements. This paper introduces a new dynamic model of full-car suspension system with semi-active suspension behavior and provides a hybrid sliding mode approach for control of full-car suspension dynamics such that the road handling stability and ride comfort characteristics are ensured. The semi-active suspension model and the hybrid sliding mode controller are implemented as Functional Mock-Up Units (FMUs) conforming to the Functional Mock-Up Interface for embedded systems (eFMI) and are calibrated with a set experimental tests using a 1/5 Soben-car test bench. The methods and prototype implementation proposed in this paper allow both model and controller re-usability and provide a generic way of integrating models and control software into embedded ECUs.

“…A vehicle suspension can be seen as a rigid body having a symmetrical structure. In general, there are three different types of vehicle suspension systems, classified as passive suspension, semi-active suspension and active suspension [1][2][3][4][5]. Passive suspension absorbs the road perturbations by using conventional springs and passive dampers installed between the sprung mass (representing the vehicle body) and the unsprung mass (representing the wheel-axle assembly).…”

Rigorous model-based design and control for intelligent vehicle suspension systems play an important role in providing better driving characteristics such as passenger comfort and road-holding capability. This paper investigates a new technique for modelling, simulation and control of semi-active suspension systems supporting both ride comfort and road-holding driving characteristics and implements the technique in accordance with the functional mock-up interface standard FMI 2.0. Firstly, we provide a control-oriented hybrid model of a quarter car semi-active suspension system. The resulting quarter car hybrid model is used to develop a sliding mode controller that supports both ride comfort and road-holding capability. Both the hybrid model and controller are then implemented conforming to the functional mock-up interface standard FMI 2.0. The aim of the FMI-based implementation is to serve as a portable test bench for control applications of vehicle suspension systems. It fully supports the exchange of the suspension system components as functional mock-up units (FMUs) among different modelling and simulation platforms, which allows re-usability and facilitates the interoperation and integration of the suspension system components with embedded software components. The concepts are validated with simulation results throughout the paper.
