This invention discloses an adjustable antenna-assisted dynamic beamforming optimization method for vehicular networks, belonging to the field of vehicular network and mobile communication technology. By establishing a comprehensive near-field multipath channel model incorporating scattering cluster distribution and geometric phase shift characteristics, this invention utilizes the position reconfigurability of a fluidic antenna system to achieve dynamic port switching within the limited space of the vehicular network terminal. This transforms multipath interference in near-field rich scattering environments into spatial diversity gain, solving the scientific problem that fixed ports cannot adapt to complex channel characteristics. Simultaneously, this invention proposes a low-complexity joint optimization algorithm based on the maximum transmission ratio and maximum signal-to-noise ratio criteria. Through closed-form solutions, it rapidly achieves the joint design of base station beamforming and terminal ports, significantly improving channel capacity without requiring only a single radio frequency link or increasing hardware costs. This effectively overcomes the stringent economic constraints of large-scale commercialization on hardware costs and computational latency.

This invention discloses a SOTIF data acquisition method and related equipment. In this invention, the cloud has a large data acquisition scope, thereby reducing reliance on closed sites or professional data collection fleets, and lowering the acquisition cost of multi-source heterogeneous data. Furthermore, First Automobile Works filters its collected multi-source heterogeneous data using first Shannon entropy and residual risk values. The filtered multi-source heterogeneous data corresponds to traffic environments with high levels of disorder. Therefore, by calling First Automobile Works to collect and upload multi-source heterogeneous data, a large amount of multi-source heterogeneous data that meets the application conditions of SOTIF can be easily obtained, providing data support for SOTIF. Moreover, the SOTIF data acquisition method is executed on the vehicle side, and by uploading the filtered multi-source heterogeneous data instead of the original full-volume data, the data processing burden on the cloud is significantly reduced, improving the implementation efficiency of SOTIF. This invention has wide applications in the automotive technology field.
