With the development of electric vehicles, the energy harvesters of vehicle’s suspensions have been widely investigated. However, most of the existing energy harvesters have replaced the original damper of the suspensions, which reduces vehicle safety. This paper proposes a magnetic energy-harvesting suspension (MEHS) for vehicles, with the advantages of high vehicle safety and a compact structure, which consists of a passive suspension and a harvester. In this paper, the working principle and the structure of the MEHS are introduced. To better analyze the magnetic field, the magnetic flux circuit model is established by combining the magnetic field division method with the magnetic equivalent circuit model. Furthermore, a dynamic model for a two-degree-of-freedom quarter-vehicle with the MEHS is built to analyze the energy-harvesting characteristics and the damping characteristics. A prototype of the quarter-vehicle that is considering the tire stiffness, is designed and manufactured, and the performances are investigated by simulations and experiments with different frequencies, external resistances and amplitudes. The experimental results indicate that the harvested peak power of the MEHS is 1.08 W with a sinusoidal input of 10 Hz and 2 mm. Moreover, the maximum energy-harvesting efficiency of the prototype reaches 67% at the sinusoidal input of 6 Hz and 2 mm. The harvested energy of the MEHS can power some electrical equipment of vehicles.

With the appearance of inerter, the ISD suspension composed of “Inerter-Spring-Damper” opens up a new direction for efficient coordination of ride comfort and road friendliness for heavy vehicles. In this paper, a reference model based on the hybrid-hook damping strategy is proposed, and the mechatronic inerter is used as an active suspension force generator in the actual controlled model. Then, the coordinated control of the vehicle ISD suspension model is realized by the model predictive control (MPC) approach. The test results show that, the RMS values of the body acceleration and dynamic tire load of the controllable ISD suspension is smaller than the traditional passive and passive ISD suspension under the sinusoidal road inputs. Under the random road input, compared with the traditional passive suspension, the controllable ISD suspension has improved the RMS value of the body acceleration by 26.61%, and the road damage coefficient has been improved by 20.13%. Experiments show that the controllable ISD suspension of heavy vehicles based on the hybrid-hook damping strategy has comprehensive improvement of vehicle ride comfort and road friendliness.

“…Many scholars have investigated the possibility of using linear electromagnetic suspension systems for vibration energy recovery. [14][15][16] Gysen et al 17,18 cooperated with the SKF corporation to develop a cylindrical linear permanent magnet actuator for BMW530i, and the vehicle can switch between the motor and the generator modes according to different road conditions. When energy recovery is required, the electromagnetic actuator can convert the vibration energy of the vehicle into electrical energy to achieve energy.…”

Adjustments in vehicle height and attitude under high-speed steering, emergency obstacle avoidance, and obstacle crossing can significantly improve the safety, mobility, and passing ability of a vehicle. At present, air and hydraulic suspensions are generally used for vehicle body height adjustment, both of which have problems of slow response and complex structures. In this study, a novel method of vehicle body height adjustment based on active suspension with a permanent magnet synchronous linear motor (PMSLM) is proposed. First, active suspension and PMSLM models are established. Then, the vehicle body height controller is designed by hierarchical control, where the upper layer uses PI control to make the vehicle body height track the desired vehicle body height and calculate the desired control force, whereas the lower layer uses the finite control set model predictive current control to make the linear motor track the desired suspension control force. For motor control, the cost function is constructed based on the minimum tracking error between the reference and predicted currents. The forward Euler discrete method is used to deduce the current prediction model for the linear motor. The simulation tests under different road classes and vehicle speeds prove that the active suspension with the PMSLM can effectively adjust the vehicle body height and has a fast response, simple structure, and does not affect ride comfort. The proposed method provides a new concept for short-term vehicle body height adjustments under specific working conditions.
