Vehicle Storage Priority Management for Transfer Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In shared storage systems, when the free space becomes insufficient, applications with lower priorities may fail to write data due to deletion of their data to accommodate higher-priority applications, leading to inefficiencies in data management.
Innovation Solution
An information processing device is configured to set a higher priority for writing transfer data compared to normal data, ensuring that transfer data from multiple applications can be written to a shared storage area while managing available space effectively by dynamically adjusting priorities and deleting data from applications with the lowest priority when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data of applications with lower priorities is deleted from the shared area to accommodate higher-priority applications, then the free space for higher-priority applications is improved, but the ability of lower-priority applications to write data deteriorates
Solution Approach 1:
The patent implements dynamic priority adjustment where the priority of transfer data is elevated above normal data only when the shared area becomes full. This dynamic reassignment allows the system to adapt storage allocation to current needs: transfer data (which requires timely transmission) receives higher priority to ensure it can be written, while normal data from lower-priority applications may be deleted to free space. This resolves the contradiction by making priority flexible rather than fixed.
2Quantity of substance
If the shared area is entirely occupied by data of applications with lower priorities, then the storage utilization is improved, but the data writing capability of higher-priority applications deteriorates
Solution Approach 1:
The system dynamically monitors the fullness of the shared area and adjusts priorities accordingly. When transfer data needs to be written and the shared area is full, the priority of that transfer data is raised above normal data priorities, enabling it to displace lower-priority normal data and be written immediately. This ensures high productivity for time-sensitive transfer operations while maintaining good storage utilization through the shared area mechanism.
3Device complexity
If fixed priorities are assigned to all applications, then the simplicity of priority management is improved, but the flexibility to handle different data types deteriorates
Solution Approach 1:
The patent applies local quality by assigning different priority characteristics to different data types based on their specific requirements. Transfer data (which needs timely transmission to data centers) is given the capability to elevate its priority locally when needed, while normal data maintains its original priority level. This localized priority adjustment provides flexibility for different data types without requiring complete reconfiguration of the entire priority system.
Solution Approach 2:
The system transitions from static priority assignment to dynamic priority adjustment. While base priorities are assigned simply to each application, the priority of transfer data can be dynamically elevated above normal data when the shared area is full, providing adaptability for different data types and situations without significantly increasing overall system complexity.

AI summary
An information processing device is configured to control writing of data to a storage mounted on a vehicle by multiple. The information processing device includes an execution device. A storage area of the storage includes a shared area shared by multiple applications. A priority for allowing writing of data to the shared area is set for each of the applications. Data of each of the applications includes transfer data to be transmitted to a data center and normal data different from the transfer data. The execution device is configured to set the priority of writing of the transfer data when the transfer data is written to the shared area to be higher than the priority of writing of the normal data.
