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.

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.

Inventive Principle:
Principle #1Segmentation

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.

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.

AI summary

An object of the present invention is to control a vehicle with less delay. A control system 100 according to the present invention includes: an estimating unit 103 that estimates a factor and a required time until encountering the factor based on a result of an observation of a periphery of a vehicle; and a deciding unit 104 that decides control contents of the vehicle based on data stored in a first storage unit 101 when the required time is longer than a threshold and that decides control contents of the vehicle based on data stored in a second storage unit 102 which can be accessed at a higher speed than the first storage unit 101 when the required time is equal to or shorter than the threshold.
