“…For instance, regenerative braking systems have been widely adopted in electric and hybrid vehicles, converting kinetic energy during deceleration into electrical energy to be stored and reused [4]. Similarly, energy-harvesting suspension systems have gained attention as a promising approach to recover energy from road-induced vibrations [5]. By transforming the energy generated during suspension movements into usable electrical energy, these systems can further enhance vehicle efficiency by capturing and reusing energy that would otherwise be dissipated as waste [6].…”

“…Hydraulic EHSA: Hydraulic energy-harvesting dampers involve the use of a hydraulic pump and motor to convert the mechanical energy generated by suspension movements into electrical energy [5]. The primary advantage of hydraulic systems is their ability to handle high forces and displacements, resulting in potentially high energy recovery rates [11].…”

In the automobile sector, energy recovery and sustainability are becoming more and more important, and energy-harvesting suspension systems (EHSAs) have a lot of promise to improve vehicle efficiency. This investigation expands on prior work that investigated the viability of an EHSA that uses permanent magnets and amorphous core coils. The performance of the proposed system is demonstrated and enhanced in the current study through the development and optimization of a prototype. A thorough testing of the prototype is performed to determine design improvements for boosting the system’s overall performance and to quantify the recovered energy. In previous work, a method was proposed to find the dependence of the magnetic flux with the relative position between the primary and secondary elements to obtain the optimal position for the system. This method is applied to optimize the energy harvesting coil by testing different configurations in terms of the placement and type of amorphous or nonamorphous core inside the energy harvesting coil. This is a crucial area of attention in order to maximize energy recovery while solving the low-frequency problem that suspension systems have (on the order of 10 Hz).

“…Good suspension structure can also improve performance. At present, many studies are aimed at new suspension, such as using regenerative shock absorber instead of the conventional passive damper [10], using negative stiffness system to improve the ride comfort [11], etc. Negative stiffness or quasi-zero-stiffness structure shows excellent performance in vibration reduction and used widely in seat suspension [12][13][14], vibration isolator [15][16], etc.…”

The zero-stiffness structure has excellent vibration attenuation performance. In this paper, a new type of zero-stiffness vibration isolator is designed, and the vibration isolation effect is simulated and analyzed. Furthermore, the zero-stiffness isolator is applied to the McPherson suspension, and the improved McPherson suspension model is obtained. Under the excitation of the bump road and C-level Road, the performance of the improved suspension is simulated, and the responses of the vehicle body vertical acceleration and suspension deflection are analyzed, and compared with that of the original suspension. The results show that, under two cases, the vertical acceleration of the improved suspension is reduced by 92.5% and 65.4% compared with the original suspension respectively, and the stability speed is also greatly improved.

“…Researchers in the automobile industry have utilized various dynamical models with different control strategies to evaluate vehicle performance in terms of ride comfort and road holding capabilities. In [ 9 , 10 , 11 , 12 , 13 ], the authors used a sophisticated two Degree Of Freedom (DOF) quarter vehicle model to improve ride comfort and road holding and utilized Linear Quadratic Regulator (LQR) and fuzzy logic control approaches. Similarly, in [ 14 , 15 , 16 ], a more complicated and ubiquitous four DOF half-car model that can be treated as a longitudinal or lateral vehicle model with an extra two DOF of roll and heave motion, crucial for ride comfort and road holding capability.…”

This paper presents a formulation of a preview optimal control strategy for a half-car model equipped with active aerodynamic surfaces. The designed control strategy consists of two parts: a feed-forward controller to deal with the future road disturbances and a feedback controller to deal with tracking error. An anti-jerk functionality is employed in the design of preview control strategy that can reliably reduce the jerk of control inputs to improve the performance of active aerodynamic surfaces and reduce vehicle body jerk to enhance the ride comfort without degrading road holding capability. The proposed control scheme determines proactive control action against oncoming potential road disturbances to mitigate the effect of deterministically known road disturbances. The performance of proposed anti-jerk optimal control strategy is compared with that of optimal control without considering jerk. Simulation results considering frequency and time domain characteristics are carried out using MATLAB to demonstrate the effectiveness of the proposed scheme. The frequency domain characteristics are discussed only for the roll inputs, while time domain characteristics are discussed for the corresponding ground velocity inputs of bump and asphalt road, respectively. The results show that using anti-jerk optimal preview control strategy improves the performance of vehicle dynamics by reducing jerk of aerodynamic surfaces and vehicle body jerk simultaneously.
