“…The energy recovery system not only recovers vibration energy, but also converts it into electrical energy that can be stored in batteries as a source of power. Since the idea of energy recovery was intensified in the last century, energy efficiency has gained in importance in the automotive industry, the research of suspensions with energy recovery systems was revived to [47].…”

As awareness regarding ecology increases among drivers, some characteristics of electric vehicles mean that they attract a greater interest. The basic factors determining the demand for electric cars include their pricing, access to charging stations and the cost per 1 kWh. Considering the above, the aim of this paper is to review the current areas of research into renewable energy sources, such as wind and solar energy and energy derived from vertical displacements of the car body associated with road roughness. The use of such solutions will allow the battery to be charged while the vehicle is in motion and extend the time of travel without stopping the vehicle for charging. The publication forms an overview of findings in the area and the scope of the research reported here relate to the most recent research. For this purpose, reviews of academic and industrial literature were carried out.

This paper reports the comparison of two physical principles of action of suspension damping devices based on their influence on the mobility indicators for an 8×8 wheeled machine. A radical difference between these principles of action is the dependence of resistance forces on the speed of the relative movement of working bodies (internal friction: hydraulic shock absorbers) or on the relative movement of working bodies (external friction: friction shock absorbers). Widespread hydraulic shock absorbers have certain disadvantages that do not make it possible to further increase the mobility of wheeled or tracked vehicles without the use of control and recuperation systems. In turn, in friction shock absorbers, the use of new materials has eliminated many of their shortcomings and thus can provide significant advantages. It was established that the application of friction shock absorbers for a given wheeled vehicle did not significantly affect the speed compared to hydraulic ones. The main factor that prevented the implementation of the advantages of friction shock absorbers was the insufficient suspension travel. However, friction shock absorbers absorbed 1.76...2.3 times less power, which reduced the load on nodes and increased efficiency (autonomy). In addition, a more uniform load on suspensions was ensured, which improved their resource, and, due to the prevailing vertical oscillations of the suspended body over the longitudinal-angular ones, the geometric passability improved as well. The comparison of two physical principles of action of damper suspension devices in a wheeled vehicle has shown that the use of friction shock absorbers could provide significant advantages in resolving the task relates to improving the mobility and would fundamentally affect the choice of the suspension energy recuperation system if it is applied.

“…Compared with the traditional passive suspension, the active suspension can improve the smoothness and handling stability of the vehicle. For the problem of high energy consumption of active suspension, the use of the electromagnetic induction principle to recover the energy of suspension vibration is not only important for improving the comfort but also the fuel economy of the vehicle [4,5].…”

This paper, the impact of time-delay feedback control on vibration energy collection and damping performance is discussed. A time-delay control system of active suspension based on a 1/4 vehicle nonlinear model is designed. The linear motor is used as the actuator of active suspension. The variable learning factor particle swarm optimization algorithm is used to optimize the optimal control parameters of active suspension with time delay. The characteristic root clustering method is proposed to analyze the stability of the active suspension control system with time delay. Finally, the energy recovery and vibration reduction of passive suspension, active suspension without time-delay, and active suspension with time-delay are simulated. The simulation results show that the energy-feeding efficiency of the active suspension with time-delay control under harmonic and random excitation is 114.54% and 20.09% higher than that of the active suspension without time-delay control. Finally, a test bench is built to verify the correctness of the simulation results. The experimental and simulation results error is within 15%, which meets the engineering requirements. The proposed method can significantly improve the energy collection capacity.
