AI Technical Summary
Existing technologies for measuring vehicle suspension height suffer from sensor measurement errors and high-frequency interference, resulting in unstable height signals. Furthermore, existing filtering algorithms exhibit low filtering accuracy or discontinuous output in nonlinear systems, affecting vehicle stability and comfort.
A first-order linear recursive filtering algorithm is adopted. By dynamically adjusting the filtering coefficient, the initial and final values of the filtering coefficient are determined based on the detection values of the height sensor and the vehicle driving information. The real-time suspension height is determined by combining the first-order linear recursive filtering algorithm.
It achieves real-time elimination of sensor measurement errors and high-frequency interference, ensuring low latency and strong noise suppression, enabling continuous changes in suspension height estimation, and improving the accuracy and stability of vehicle suspension control.
