Applications and Challenges of Electromechanical Integrated Transmission Systems in Intelligent Vehicles

With the rapid development of intelligent vehicles and the global push for carbon neutrality, Electromechanical Transmission (EMT) systems have attracted wide attention for their unique benefits. This paper provides an in-depth analysis of the three primary EMT architecturesseries, parallel, and series-parallel hybrid configurationshighlighting their structural characteristics and operational principles. The study identifies key research directions focusing on enhancing energy utilization efficiency, improving drivability, and reducing system costs. Furthermore, it examines the current applications of EMT systems in intelligent vehicles, delineates the challenges encountered, and explores critical technologies such as lightweight design, hybrid power cooperative drive, and intelligent control strategies. The paper also evaluates various methodologies and algorithms employed within these technologies, assessing their respective advantages and limitations. Looking ahead, EMT systems are poised to play an increasingly pivotal role across multiple domains. However, to fully realize their potential, it is imperative to address prevailing issues related to system reliability, cost-effectiveness, and the integration of advanced intelligent control mechanisms, thereby contributing to the sustainable development of the automotive industry.
