Vehicle Software Update Scheduling by Processing Unit Risk
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing software update technologies fail to ensure safety and efficiency in updating software programs, particularly in high-frequency use scenarios like vehicle automation, due to inadequate defect recognition and delayed updates, leading to potential safety risks.
Innovation Solution
An information processing system and method that updates software for each processing unit of a moving apparatus, prioritizing updates in vehicles with lower risk scenarios and confirming operational safety before distributing to other vehicles, thereby ensuring quick and safe software updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If software update is performed by waiting for complete development and thorough testing to eliminate all defects, then safety is improved, but update time and distribution speed are significantly delayed
Solution Approach 1:
The patent segments the software system into multiple processing units that can be updated independently. This allows incremental updates rather than requiring complete software re-development and testing, thereby reducing update time while maintaining safety through controlled deployment of individual units
Solution Approach 2:
The patent implements preliminary safety confirmation through simulation environments before actual deployment. By pre-validating update candidates in virtual settings and using rollback mechanisms, safety is ensured without requiring extensive real-world testing, thus accelerating the update process
2Productivity
If software update is performed quickly without sufficient development and testing, then update speed is improved, but safety and reliability deteriorate due to potential defects
Solution Approach 1:
The patent implements a feedback mechanism where operating state information is collected from vehicles after update deployment. This feedback loop allows continuous monitoring of update performance and enables rapid identification and correction of any defects, maintaining safety while enabling quick updates
Solution Approach 2:
The patent employs dynamic update strategies where the update deployment process can be adjusted based on real-time conditions. Updates can be paused, rolled back, or modified based on observed system behavior, allowing fast deployment while adapting to maintain safety
3Reliability
If update timing is set during vehicle stop states to ensure safety, then safety is improved, but update opportunity frequency is reduced in high-use vehicles
Solution Approach 1:
The patent implements periodic safety confirmations and staged update deployments rather than requiring complete vehicle stoppage. By using periodic checks during operation and incremental deployment strategies, updates can occur more frequently without compromising safety
Solution Approach 2:
The patent introduces simulation environments and virtual testing platforms as intermediaries between development and actual deployment. This intermediary layer allows extensive validation without requiring vehicle stoppage, enabling more frequent updates while maintaining safety standards
4Productivity
If update is performed in high-frequency use vehicles, then update benefit is improved, but safety risk increases due to limited opportunities for safety confirmation
Solution Approach 1:
The patent performs preliminary safety validations through simulation environments before deploying updates to high-frequency use vehicles. By pre-confirming safety in virtual settings and using rollback mechanisms, the actual deployment risk is minimized while allowing continuous operation and faster benefit realization
Solution Approach 2:
The patent implements enhanced feedback mechanisms for high-frequency use vehicles, including real-time monitoring and rapid response protocols. This allows continuous operation with updates while maintaining safety through active monitoring and quick defect response

AI summary
The present disclosure relates to an information processing apparatus, an information processing method, an information processing system, and a program that enable update of an SW to be quickly and safely implemented. When the software program (SW) is updated, the SW is updated at a timing at which the SW does not operate in a plurality of processing units constituting the SW, so that the SW is updated without stopping the entire operation of the SW. The present disclosure can be applied to an automated driving technology.
