AI Technical Summary
Existing vehicle positioning systems struggle to achieve centimeter- to decimeter-level accuracy when vehicles are operating on highways under conditions of high obstruction, multiple paths, weak networks, and cellular link jitter. Furthermore, electronic fence detection suffers from false alarms and failure to alert, leading to track breaks and weakened safety control capabilities.
By employing a multi-source fusion method based on BeiDou inertial coordination, and combining unified event time, dynamic lever correction, adaptive model switching, probabilistic correlation and dual-time axis smoothing with HPL sensing fence, a continuous processing chain is constructed to achieve high-precision positioning and trajectory continuity.
Achieve centimeter/decimeter-level positioning accuracy in complex environments, reduce cross-modal misalignment, ensure trajectory continuity and fence determination accuracy, and meet end-to-end low latency and auditability requirements.
