Reroute Path Handling for Continuous Autonomous Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems face interruptions in autonomous driving control when a navigation device reroutes to generate a new traveling route due to limitations in data capacity and transmission between high-precision map information management devices.
Innovation Solution
An information processing method and device that suppresses interruptions by managing path information through deletion processes based on path types and bifurcations, allowing continuous autonomous driving control during reroutes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the navigation device reroutes to generate a new traveling route, then the route accuracy is improved, but the autonomous driving control is interrupted
Solution Approach 1:
The system performs preliminary actions by having the information processing device prepare to receive and process reroute information before the navigation device actually reroutes. The device maintains readiness to accept new traveling route data, ensuring that when rerouting occurs, the transition is seamless and autonomous driving control continues without interruption.
Solution Approach 2:
The information processing device acts as an intermediary between the navigation device and the autonomous driving control system. It receives reroute information from the navigation device, processes it by extracting necessary elements, and provides the processed information to maintain autonomous driving control, thus mediating the transition during rerouting.
2Measurement precision
If high-precision map data is used for route projection, then the route accuracy is improved, but the data transmission load is increased
Solution Approach 1:
The information processing device extracts only the necessary elements from the reroute information received from the navigation device. Instead of transmitting or processing the entire high-precision map data set, it selectively extracts relevant route elements needed for autonomous driving control, thereby reducing data transmission load while maintaining route accuracy.
Solution Approach 2:
The system segments the route information processing into distinct components: the navigation device generates the complete traveling route, the information processing device extracts necessary elements, and the autonomous driving control system receives only the essential segmented data. This segmentation allows high-precision routing while minimizing data transmission requirements.

AI summary
An information processing method and an information processing device acquire a path information on a path included in a road network set on a map data, acquire a reroute request indicating an instruction to regenerate a route when generating the route that a vehicle is scheduled to travel in correspondence with the road network based on the path information stored in the database, acquire a path type indicating whether a target path on which the vehicle is traveling at a timing when the reroute request is acquired is a first path or a second path bifurcating from the first path, included in the road network, and delete the path information stored in the database based on the path type.
