Autonomous Driving Map Switching With Unified Data Interpretation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving devices face challenges in acquiring necessary information for navigation when using maps with different recording targets, as they require distinct methods for each map, leading to inefficiencies and potential speed constraints.
Innovation Solution
An autonomous driving device that determines necessary information using a unified method by treating absent recording targets as null values, allowing it to select and use either map based on conditions such as content availability, date of update, and override rates, thereby enabling consistent navigation across multiple maps.
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 determines necessary information (first content) and optional information (second content) using the same procedural approach regardless of which map is being used. When the second content is not recorded in a map, the system treats it as a null value, allowing the same method to function universally across diverse map formats and standards.
2Measurement precision
If a detailed map is created for all roads, then the navigation accuracy is improved, but the manufacturing cost increases
Solution Approach 1:
The patent applies local quality by allowing different maps to have different levels of detail and different recording targets based on their specific purposes and creation standards. Each map can optimize its content for its intended use case without requiring all maps to contain every possible type of information. The system adapts to the local characteristics of each map while maintaining consistent processing methods.
3Adaptability or versatility
If maps with different recording targets are used, then the versatility of the system is improved, but the consistency of information acquisition methods deteriorates
Solution Approach 1:
The patent establishes a universal information acquisition methodology that maintains consistency across different map formats. The control unit follows the same determination process for both first content (necessary information) and second content (optional information) regardless of which map is being processed. This universal approach ensures method consistency while accommodating map format flexibility.
Solution Approach 2:
The patent introduces an intermediary mechanism where the control unit acts as a mediator between diverse maps and the autonomous driving system. By standardizing how information is extracted and interpreted from different map sources, the control unit enables consistent processing while allowing maps to maintain their own characteristics and recording standards.

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.
