Vehicle Reporting Device for Outside Recognition Failure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Connected cars with autonomous drive or drive assist functions lack adequate information to properly control vehicles based on outside recognition results, as the factors contributing to abrupt brakes cannot be clearly deduced from mere occurrence frequency, and existing technologies do not account for vehicle behavior or recognition precision.
Innovation Solution
A reporting device connected to vehicles via a network provides information on the possibility of outside recognition failure by analyzing previous failure conditions, using a combination of recognition results, vehicle behavior, and external environment data to identify non-detection or erroneous detection, and notifying the vehicle accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a connected car uses autonomous drive or drive assist functions based on outside recognition results, then the vehicle control automation is improved, but the reliability of vehicle control deteriorates due to inability to properly assess outside recognition failure possibilities
Solution Approach 1:
The reporting device collects outside recognition results, vehicle behavior data, and external environment information, then feeds back failure possibility information to the vehicle. This feedback loop enables the autonomous drive system to adjust its operation based on assessed reliability, resolving the contradiction between automation and reliability.
Solution Approach 2:
The system performs preliminary assessment of outside recognition failure possibilities by analyzing historical data and current conditions before actual failures occur. This preliminary action allows the autonomous drive system to prepare appropriate responses, maintaining both automation and reliability.
2Device complexity
If the vehicle relies solely on occurrence frequency of abrupt brakes, then the data processing complexity is reduced, but the measurement precision of failure factors deteriorates
Solution Approach 1:
The system segments the analysis into multiple independent components: outside recognition results, vehicle behavior data, external environment information, and failure possibility assessment. This segmentation allows comprehensive analysis without excessive complexity, improving precision while managing complexity through modular processing.
3Ease of operation
If the outside recognition system operates without failure possibility information, then the system operation is simplified, but the safety of autonomous drive deteriorates
Solution Approach 1:
The reporting device acts as an intermediary between the outside recognition system and the autonomous drive control. It adds failure possibility assessment without complicating the core recognition system, enabling safety improvements while maintaining operational simplicity through a dedicated intermediate component.

AI summary
A reporting device that is connected to at least one vehicle, which is controlled based on a result of recognition by an outside recognizer, via a network provides the vehicle with information on a possibility of a failure in outside recognition on the basis of a condition under which a failure in outside recognition has occurred previously. Preliminarily, if a failure such as non-detection or erroneous detection occurs due to an outside recognizer of a connected car, the abnormality is stored while being linked with an external traveling environment such as the position of the vehicle or a weather.
