Vehicle Software Identifier Consistency Check
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles, especially those with autonomous capabilities, face challenges in maintaining software and hardware consistency, leading to potential safety and efficiency issues due to inconsistencies in identifiers, which existing systems fail to address effectively.
Innovation Solution
A system that periodically checks and updates identifiers by comparing local and remote sets, preventing autonomous mode entry if inconsistencies are found and performing a minimal risk condition, while ensuring timely software updates and diagnostic trouble codes are set to address inconsistencies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software and hardware identifiers are not regularly checked for consistency, then system complexity and operational flexibility are maintained, but safety and reliability deteriorate due to potential inconsistencies
Solution Approach 1:
The system performs preliminary checks by comparing local identifiers with remote identifiers before allowing autonomous mode operation. This preventive approach ensures consistency is verified in advance, preventing unsafe operations while maintaining system reliability without requiring continuous complex monitoring during operation.
Solution Approach 2:
The system establishes a feedback mechanism where identifier consistency results are communicated back to the autonomous mode controller. This feedback loop enables the system to make informed decisions about mode transitions based on consistency verification, ensuring reliability while using a relatively simple binary check rather than continuous complex analysis.
2Reliability
If identifier consistency checks are performed frequently, then safety and reliability are improved, but processing time and computational resources increase
Solution Approach 1:
The system performs identifier consistency checks periodically rather than continuously, and specifically triggers checks before autonomous mode transitions. This periodic approach maintains safety by verifying consistency at critical decision points while minimizing processing time and computational resource usage during normal operation.
3Reliability
If autonomous mode is prevented due to identifier inconsistencies, then safety is improved, but productivity and operational efficiency deteriorate
Solution Approach 1:
The system performs preliminary identifier consistency verification before allowing autonomous mode entry. By checking consistency in advance, the system ensures safety requirements are met while enabling autonomous operation when conditions are appropriate, thus maintaining productivity without compromising safety.
Solution Approach 2:
The system uses feedback from identifier consistency checks to make intelligent decisions about autonomous mode authorization. When identifiers are consistent, the system permits autonomous operation, maintaining productivity. When inconsistencies are detected, it prevents autonomous mode, ensuring safety. This conditional approach balances both concerns effectively.

AI summary
A computer includes a processor and a memory storing instructions executable by the processor to, upon determining that a local set of identifiers is inconsistent with a remotely served set of identifiers, prevent a vehicle from entering an autonomous mode or instruct the vehicle to perform a minimal risk condition.
