The invention relates to the technical field of vehicle suspension system control, and discloses a multi-source data fused shock absorber self-adaptive regulation and control method and system.The method comprises the steps that multi-source signal data are synchronously collected through a sensor, and a preliminary signal set is generated in combination with environment change data; analyzing vibration signal peak amplitude and displacement data integral variation trend, distinguishing high-frequency small-acceleration and low-frequency large-amplitude pavement excitation characteristics, and determining signal contribution degree distribution; dynamically adjusting the signal weight and introducing temperature compensation to correct stiffness drift to generate a weighted vector; carrying out weighting processing, smoothing, noise suppression and nonlinear amplitude estimation to generate fusion data, and optimizing the weight to obtain a refined weighted vector; after secondary fusion, a cross-frequency-band transition smoothing technology and a least square method are adopted to determine damping characteristic parameters; according to the vehicle suspension system self-adaptive regulation and control method and system, the self-adaptive regulation and control accuracy and the working condition adaptability of the vehicle suspension system are improved.

This invention discloses a predictive transmission feedback method and system based on trajectory-aware modeling. The method includes: a receiver preprocessing the received signal to form basic observation information and constructing trajectory-aware observation information, including the complex plane position of the equalization symbol, geometric deviation information relative to the reference constellation point, and corresponding reliability statistics and channel quality information; inputting the trajectory-aware observation information into a trajectory-aware modeling network for feature extraction and generating a risk score through a risk prediction branch, and generating policy priors and recommended actions through a policy generation branch; based on the risk score and policy priors and / or recommended actions, forming predictive transmission feedback information and feeding it back to the transmitter; and the transmitter adaptively adjusting subsequent transmission strategies after receiving the predictive transmission feedback information. This invention can generate more instructive feedback content in short-packet high-reliability transmission scenarios, improving transmission reliability and enhancing system latency and energy efficiency.
