AI Technical Summary
Existing vehicle positioning methods, particularly for autonomous vehicles, face challenges in ensuring accuracy due to map inaccuracies and irregular road trajectories, leading to reduced positioning precision and safety.
A method and apparatus for vehicle positioning that involves determining real-time road information and matching it with target map road information, using sensing systems to identify road types and performing positioning corrections based on linear correlation coefficients and lane line information to ensure accurate vehicle positioning on different road types.
Enhances positioning accuracy and improves safety by ensuring precise vehicle positioning and enhancing dead reckoning accuracy, particularly on roads with varying geometries.
