AI Technical Summary

Technical Problem

Existing navigation systems provide vehicle routes based on waypoints that do not align well with high-definition (HD) map data, leading to insufficient lane-level information for drivers and vehicle applications, which can result in inefficient lane changes and increased computing resources.

Method used

A vehicle control system that aligns navigation routes with HD map data by identifying road segments and lanes based on geometric relationships and endpoint distances, using polygon-defined road segments and determining a preferred lane for vehicle control.

Benefits of technology

Efficiently provides lane-level guidance with minimal computing resources, enabling precise vehicle control and reduced computational load by aligning navigation routes with HD map data.

Abstract

A vehicle system comprises a vehicle control module and a control module. The control module is configured to receive a navigation route, a plurality of road segments defined by polygons, identify a set of road segments from the plurality of road segments based on the distance between one or more waypoints of the navigation route and the polygons, determine the lanes of the road segments along the navigation route and the endpoint distances for the lanes for each road segment from the set of road segments along the navigation route, and identify a preferred lane along the navigation route based on the endpoint distances for the lanes. The vehicle control module is configured to generate a control signal to control at least one operation of the vehicle based on the identified preferred lane along the navigation route.Other vehicle systems and procedures are also disclosed.
