Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing navigation systems fail to provide precise and timely auxiliary prompts based on both navigation and environmental information, leading to potential collisions and inefficient driving experiences due to inaccurate or untimely guidance.
Innovation Solution
A method and apparatus that determine the type and output time of auxiliary prompts using navigation and environment information, ensuring safe and efficient driving by integrating roadside devices, vehicle sensors, and a navigation application to provide targeted prompts at optimal times, such as lane changes or decelerations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If navigation information alone is used for guidance, then the system complexity is low, but the guidance precision and timeliness deteriorate
Solution Approach 1:
The patent combines navigation information with environment information from multiple sensors (cameras, radar, lidar) to create a comprehensive guidance system. This merging of information sources resolves the contradiction by achieving high guidance precision through multi-source data integration while managing system complexity through coordinated processing of combined inputs.
Solution Approach 2:
The system performs preliminary analysis of both navigation and environment information to determine in advance whether auxiliary prompt information is needed. By pre-processing and comparing data sources before generating prompts, the system achieves timely and precise guidance while optimizing computational efficiency and managing complexity.
2Ease of operation
If auxiliary prompt information is provided continuously, then the user experience improves, but the information loss increases due to excessive or irrelevant prompts
Solution Approach 1:
The patent applies local quality by providing auxiliary prompt information selectively based on specific conditions and contexts. Rather than continuous uniform prompting, the system determines whether prompts are needed based on local environmental factors and navigation requirements, ensuring prompts are provided only where and when necessary for optimal user experience without information overload.
3Reliability
If the output time of auxiliary prompts is delayed, then the system reliability improves, but the productivity deteriorates due to late guidance
Solution Approach 1:
The system performs preliminary determination of whether auxiliary prompts are needed by analyzing navigation and environment information in advance. This pre-assessment allows the system to output prompts at the optimal moment - early enough to maintain driving efficiency but timed precisely to ensure system reliability and avoid premature or late guidance.
