“…Designing a sliding mode controller for both the suspension and the TMD is an effective method for improving ride comfort and suppressing vibrations, as demonstrated by the suggested method, which showed better response in vibration management and led to improved ride comfort and road-holding. The study in [121] analyzed the effects of IWM on vehicle stability, safety, and ride comfort based on a quarter vehicle suspension model. During simulations, the occurrence of wheel hop, which is dependent on unsprung mass and tire stiffness, was monitored.…”

“…Ref. [121] analyzed the impact of an in-wheel motor (IWM) suspension system on the ride comfort of electric vehicles (EVs) by considering various road surface roughness and IWM mass conditions. The study found that the IWM suspension system significantly improved EV ride quality, reducing the weighted root-mean-square acceleration of the vertical vehicle body by 8.6% compared to without the IWM suspension system.…”

Recently, there has been significant attention given to the electrification of transportation due to concerns about fossil fuel depletion and environmental pollution. Conventional drive systems typically include a clutch, reduction gear, and mechanical differential, which results in power loss, noise, vibration, and additional maintenance. However, in-wheel motor drive technology eliminates the need for these components, providing benefits such as higher system efficiency, improved wheel control, and increased passenger comfort. This article offers a comprehensive review of the technology and development of in-wheel motor drives. It begins with an overview of in-wheel motor drives in electric vehicles, followed by an exploration of the types of electric motors suitable for in-wheel motor drives. The paper then presents an industrial state of the art of in-wheel motors, comparing them with conventional motor drives, and reviews the implemented power electronics, control system, and cooling systems. Finally, the paper concludes by providing an outlook on the challenges and future trends of in-wheel drive systems.
