Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic control units (ECUs) face limitations in rapidly processing signals and improving response characteristics, making it difficult to enhance signal processing rates and response times.
Innovation Solution
An integrated ECU is designed with a gateway for network communication, featuring vehicle motion, safety, and driving main controllers, along with sub-controllers that perform cooperative control and manage network traffic to optimize signal processing and response times by distributing and prioritizing sensing information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a conventional detachable controller is used with a main controller and sub-control modules, then the device complexity is reduced and ease of manufacture is improved, but the signal processing rate and response characteristics deteriorate
Solution Approach 1:
The controller is divided into a main controller and multiple sub-control modules, each responsible for specific sensing information domains (motion, safety, driving). This segmentation allows parallel processing of different sensing signals, improving the overall signal processing rate while maintaining manufacturing simplicity through modular design.
Solution Approach 2:
A communication bus serves as an intermediary between the main controller and sub-control modules, enabling rapid data exchange. The bus architecture facilitates high-speed signal transmission and coordination, resolving the contradiction between modular ease of manufacture and the need for fast signal processing.
2Ease of manufacture
If a conventional detachable controller is used with a main controller and sub-control modules, then the device complexity is reduced and ease of manufacture is improved, but the response characteristics deteriorate
Solution Approach 1:
By segmenting the controller into specialized main and sub-control modules, each module can independently process its designated sensing information without waiting for sequential processing by other modules. This parallel architecture reduces response time while keeping the system manufacturable through standardized modular components.
Solution Approach 2:
Sub-control modules are pre-configured with specific processing functions for different sensing domains (motion, safety, driving). This preliminary configuration allows immediate processing of incoming signals without requiring complex real-time decision-making, thereby reducing response time while maintaining ease of manufacture through pre-programmed modular units.
