Driving Assistance Information Delivery for Dynamic Function Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated driving and driving assistance systems lack the ability to determine whether to restrict functions based on real-time environmental conditions, such as road conditions, weather, and infrastructure compatibility, which are crucial for safe operation.
Innovation Solution
A system that acquires and processes information from various sources to determine the necessity of restricting automated driving or assistance functions, using a driving assistance information delivery apparatus with an information acquisition unit, requirement item extraction unit, and information delivery unit to provide necessary restriction information to vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated driving or driving assistance functions are restricted under unsuitable environmental conditions, then safety is improved, but operational capability deteriorates
Solution Approach 1:
The system dynamically adjusts the operational status of automated driving or driving assistance functions based on real-time environmental conditions. The control unit receives information about road conditions, weather, and infrastructure compatibility, then automatically switches between enabled and restricted states, making the system adaptive rather than static.
Solution Approach 2:
The system implements a feedback mechanism where the control unit continuously monitors environmental conditions through information receiving units, compares them against safety criteria, and adjusts the operational status accordingly. This closed-loop control ensures that safety restrictions are applied only when necessary based on actual environmental feedback.
2Measurement precision
If the system acquires and processes information from multiple information provision apparatuses, then determination accuracy is improved, but system complexity increases
Solution Approach 1:
The system segments the information processing function across multiple independent information provision apparatuses, each responsible for providing specific types of environmental information (road conditions, weather, infrastructure). This modular approach allows the control unit to receive and process information from distributed sources without creating a single complex processing bottleneck.
Solution Approach 2:
The control unit is designed with multi-functionality to handle various types of environmental information from different sources. It can process information about road conditions, weather conditions, and infrastructure compatibility through a unified information receiving and processing mechanism, reducing overall system complexity despite multiple information sources.
