Autonomous Driving Map Handling for Mixed Recording Targets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems face challenges in acquiring necessary information for navigation when using maps with different recording targets, as each map is created according to unique standards, leading to inconsistencies in data recording and methods for information acquisition.
Innovation Solution
An autonomous driving device that incorporates a control unit capable of determining necessary information using a unified method across multiple maps by associating first and second contents with positions, treating the second content as absent when not recorded, allowing for consistent information acquisition regardless of map differences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple maps with different recording targets are used, then the coverage and adaptability of the autonomous driving system is improved, but the complexity of information acquisition methods increases
Solution Approach 1:
The patent applies universality by creating a unified information acquisition method that works across multiple maps with different recording targets. The control unit uses the same processing logic regardless of which map is being used, making the system compatible with various map standards and organizations without requiring separate acquisition methods for each map type.
Solution Approach 2:
The patent changes the parameter approach by treating missing map content as having a default value (null or zero) rather than requiring different acquisition methods. This parameter change allows the control unit to handle any map type uniformly by simply checking whether specific content exists at given positions, converting a methodological complexity into a simple parameter check.
2Reliability
If detailed maps are created for all roads, then the accuracy and completeness of autonomous driving information is improved, but the cost of map creation increases
Solution Approach 1:
The patent applies partial action by allowing maps to contain only the specific content types that particular organizations or companies choose to record, rather than requiring all possible content types in every map. This partial approach reduces the cost and effort of map creation while still providing sufficient information for autonomous driving through the unified acquisition method.

AI summary
An autonomous driving device includes a first map including a first content and a second content associated with positions respectively, a second map including the first content associated with the position and in which the second content is not a recording target, and a control unit performing the autonomous driving. When the autonomous driving is performed using the first map, the control unit determines information necessary for the autonomous driving using a first method based on the first content and the second content. When the autonomous driving is performed using the second map, the control unit determines the information necessary for the autonomous driving using a method same as the first method based on the first content corresponding to a second position recorded in the second map and information indicating that the second content corresponding to the second position recorded in the second map is not present.
