To systematically clarify the research context and future directions of automotive electronically controlled suspensions, this paper reviews the latest progress in three categories of active/semi-active suspensions—hydraulic, pneumatic, and electromagnetic. It categorically describes the composition, principles, and application status of three electronically controlled suspension systems: electro-hydraulic active suspension, electro-pneumatic active suspension, and electromagnetic active suspension. It analyzes classic control methods currently applied in these systems, including PID control, state-feedback control, and neural-network control, as well as modern control methods such as robust control, sliding-mode control, and adaptive control. A brief overview of domestic and international research achievements related to these control methods is provided. Finally, the paper summarizes future research directions and development trends in active suspension control strategies.
