Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electric devices, such as ECUs, face delays in data reading due to management processing, which can hinder quick completion of memory operations.

Innovation Solution

An electric device with a first memory for control-related data and a second memory for non-control data, where data reading is prioritized followed by management processing, and execution times are monitored to skip certain processing items based on detected execution times.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If management processing is executed when reading data from memory, then data reliability is improved, but reading speed deteriorates

Engineering Contradiction:

Improvedata reliabilityVSAvoidreading speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent segments memory into first memory (storing control-related data) and second memory (storing non-control data). The reading control section prioritizes reading from first memory without executing management processing, achieving fast reading speed for critical data, while management processing is executed separately for second memory to ensure data reliability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Different reading strategies are applied to different memory regions: first memory uses a simple reading strategy without management processing for speed, while second memory uses management processing for reliability. This local differentiation resolves the contradiction by optimizing each region according to its specific requirements.

Inventive Principle:

Principle #3Local quality

2Reliability

If management processing is executed for second memory, then data management reliability is improved, but processing time increases

Engineering Contradiction:

Improvememory management reliabilityVSAvoidprocessing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The execution time detection section detects whether management processing has already been executed previously. If management processing was already executed, the system skips redundant execution, thereby reducing processing time while maintaining data reliability through the preliminary action of checking execution status.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system executes management processing partially - only when necessary and only for the second memory - rather than executing it fully for all memory operations. This selective execution reduces overall processing time while maintaining sufficient reliability for the non-critical second memory.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

There is provided an electric device, comprising: a first memory that stores first data participating with control of the vehicle; a second memory that stores second data not participating with control of the vehicle; a reading controlling section that reads the second data subsequently to reading the first data; a management processing executing section that, when the reading controlling section reads the second data, executes management processing for managing the second memory; and an execution time detecting section that detects an execution time of the management processing, wherein the management processing executing section does not execute, out of a plurality of processing items included in the management processing, one or parts of the processing items, based on the execution time detected by the execution time detecting section.
