A Survey on Reinforcement Learning for Optimal Decision‐Making and Control of Intelligent Vehicles

CAAI Transactions on Intelligence Technology, Volume 10, Issue 6, Page 1593-1615, December 2025.
ABSTRACT Reinforcement learning (RL) has been widely studied as an efficient class of machine learning methods for adaptive optimal control under uncertainties. In recent years, the applications of RL in optimised decision‐making and motion control of intelligent vehicles have received increasing attention.

Control of Semiactive Suspension Systems Using Preview Information and Convolutional Neural Networks

Shock and Vibration, Volume 2025, Issue 1, 2025.
Due to the complexity and variability of road conditions during vehicle operation, the ability of suspension systems to effectively suppress vehicle vibrations is often limited. To enhance ride comfort of the vehicle across varying road surfaces, a preview control strategy is designed based on the convolutional neural network (CNN) and skyhook control ...

Influence of temperature and internal leakage on magnetorheological damper

International Journal of Mechanical System Dynamics, Volume 4, Issue 4, Page 487-496, December 2024.
Abstract To study the influence of temperature and internal leakage on the performance of magnetorheological (MR) damper, a single‐rod straight‐cylinder MR damper with an inside temperature sensor is designed in this study. A unified model for MR damper is given, and a new two‐step parameters identification method is proposed to determine model ...

Experimental verification of temperature effects on functional parameters in a line start permanent magnet synchronous motor

IET Science, Measurement &Technology, Volume 18, Issue 9, Page 491-498, November 2024.
The paper deals with the finite element (FE) analysis of the temperature influence on functional parameters of the line start permanent magnet synchronous motor (LSPMSM). The two‐dimensional (2D) FE model of coupled electromagnetic and thermal phenomena in the LSPMSM was described.

High‐Performance and High Bandwidth Electroadhesive Clutch Enabled by Fracture Mechanics and a Dielectric Nanoparticle‐Based High‐k Composite

Advanced Materials Technologies, Volume 9, Issue 14, July 22, 2024.
High force electroadhesive clutch enabled by considering fracture mechanics and using BaTiO3/P(VDF‐TrFE‐CTFE)‐based dielectric coating shows high EA shear stress up to 108 N cm−2 at 300 V. This also enables low voltage operations of a wide range of applications and miniaturization of devices while providing the sufficient EA force.
