AI Technical Summary
Traditional vehicle suspension systems cannot adaptively adjust to real-time road conditions and vehicle dynamics, making it difficult to balance ride comfort and handling stability. Furthermore, existing adjustable dampers have control lag and cannot achieve predictive optimization before impacts occur.
An integrated system consisting of a road condition sensing unit, a predictive control unit, and an actuator assembly is adopted. It acquires road information in real time through stereo vision, lidar, millimeter-wave radar, and vehicle-to-everything (V2X) communication. Combined with a vehicle dynamics model, it predicts the time point when the wheels contact obstacles and adjusts the damping of the electromagnetic damper and the air pressure of the adaptive stiffness spring assembly to achieve active and precise vibration reduction control.
It significantly improves ride comfort and handling stability. By adjusting the stiffness of the shock absorbers and springs before an impact through a predictive control system, it achieves a dynamic balance between comfort and sportiness in the shock absorption system, overcoming the bottleneck of the non-adjustable stiffness of traditional suspension systems.
