Faced with pressures from environmental regulations and consumer demands for efficiency and performance, active aerodynamics has become a core technology for optimizing vehicle performance. This paper examines the technical system of automotive active aerodynamics, focusing on dynamic adjustable components, integration with energy recovery systems, and intelligent control algorithms. Dynamic adjustable components including diffusers, active grilles, and active spoilers, achieve real-time aerodynamic optimization through multi-mode adjustments. The integration of active aerodynamics with energy recovery systems breaks traditional design limitations. It reduces energy consumption of electrified vehicles via high-speed drag reduction and maintains battery/motor temperature stability through targeted airflow control, reducing efficiency loss caused by extreme temperatures. Additionally, multi-source sensor data fusion solving single-sensor limitations and deep learning-based short-term condition prediction (e.g., LSTM and CNN-LSTM models) upgrade aerodynamic systems from “passive response” to “proactive adjustment”, enhancing control precision.
