Vehicle Control System Dual Storage for Reduced Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face delays in responding to factors that require immediate action, as they rely on slower data access methods when time constraints are tight.
Innovation Solution
The system employs a dual storage approach, using volatile storage for rapid access when time until encountering a factor is short and non-volatile storage for longer times, allowing for quicker decision-making and action execution.

1Quantity of substance
If data is stored in non-volatile storage, then data capacity is increased, but data access speed is reduced
Solution Approach 1:
The storage system is segmented into two distinct parts: volatile storage unit (first storage unit) and non-volatile storage unit (second storage unit). Each segment serves a specific purpose based on the time constraint characteristics, allowing the system to leverage the high speed of volatile storage for urgent cases while utilizing the large capacity of non-volatile storage for less time-sensitive data.
Solution Approach 2:
The system dynamically selects which storage unit to access based on the time constraint condition. When the time constraint is shorter than a threshold, the volatile storage unit is accessed; when the time constraint is longer than the threshold, the non-volatile storage unit is accessed. This dynamic selection optimizes the balance between access speed and data capacity.
2Loss of time

3Device complexity
If a single storage unit is used, then system complexity is reduced, but control accuracy under different time constraints is degraded
Solution Approach 1:
The storage system is segmented into two distinct parts: volatile storage unit (first storage unit) and non-volatile storage unit (second storage unit). Each segment serves a specific purpose based on the time constraint characteristics, allowing the system to leverage the high speed of volatile storage for urgent cases while utilizing the large capacity of non-volatile storage for less time-sensitive data.
Solution Approach 2:
Different storage units are assigned different quality characteristics: the volatile storage unit provides high-speed access suitable for time-critical operations, while the non-volatile storage unit provides large capacity for comprehensive data storage. This local quality differentiation ensures that each storage unit is optimized for its specific function.
