“…The vibration can be caused by the mechanical resonance of the ELF. Previous studies have reported that trucks exhibit mechanical resonance in the low-frequency range owing to their heavy mass and low rigidity (Hassan and McManus, 2002; Koayashi, 2012; Ramakrishnan and Pecht, 2004; Vanliem et al, 2020). Vibration negatively impacts yaw-rate control and the risk of cargo damage.…”

“…The natural frequency of the vibration mode in a truck tends to be lower because of its mass and low rigidity (Soleimani and Ahmadi, 2014). In particular, large vibrations are known to occur at 1–3 Hz due to the unevenness of the road surface during the lateral control of the truck (Hassan and McManus, 2002; Koayashi, 2012; Ramakrishnan and Pecht, 2004; Vanliem et al, 2020). The control system can lose steering control through vibrations.…”

“…The first approach is a vibration control by using the truck suspension system. The dynamic model of the truck is derived based on the motion of the equation (Koayashi, 2012; Vanliem et al, 2020), or a multibody dynamics software is used for the analysis of the vibration (Wang and Gao, 2018). These methods can clarify the relationship between the stiffness coefficient and frequency response of the vibration.…”

The role of truck transportation is becoming increasingly important in the growth of the e-commerce market. Self-driving trucks are being developed for efficient transportation. To realize a safe self-driving system, the control system should compensate for various vibrations while the truck is running. In the yaw direction, the mechanical resonance of the chassis suspension can cause low-frequency vibration. There are two approaches to compensate for the vibration. The first is a vibration control by using the truck suspension system. The method effectively compensates for vibration; implementing additional parts increases the cost. The second is vibration control based on the yaw-rate feedback control system. A notch filter or a lowpass filter decreases the gain at the vibration frequency and is effective in compensating for vibrations. The tracking performance of the reference signal can be degraded by decreasing the gain in the low-frequency range. Therefore, it is required that a solution can compensate for the vibration without the additional parts and no performance degradation. This paper proposes the use of an adaptive feed-forward cancellation (AFC) to compensate for low-frequency vibrations in the yaw-rate feedback control system. The AFC generates a compensation signal based on the difference between the reference signal and the actual yaw rate. The AFC does not reduce the gain near the vibration frequency; therefore, the AFC can achieve low-frequency vibration compensation while maintaining the tracking performance. In addition, the proposed control system does not require additional parts. The effectiveness of the proposed method was verified by experiments using an actual commercial truck.

“…As the main means of freight transportation, scholars have done a lot of research to improve the performance of heavy vehicles, [1][2][3][4][5] especially the road damage 6,7 caused by heavy vehicles. In order to improve the ride comfort and road friendliness of heavy vehicles, Gong and Yan Mingde 8 proposed a new adaptive robust control strategy based on road level estimation for heavy rescue vehicles to improve ride comfort and handing stability.…”

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.
