Relay Device for Drive Assist ECU Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive assist network systems face challenges in updating functions due to the need for extensive changes across all ECUs, making it difficult to add new drive assist ECUs and integrate advanced features without significantly altering the system.
Innovation Solution
A relay device, such as a filtering controller, is used to transmit control data from a new add-on ECU instead of the existing drive assist ECU, allowing for functional updates by relaying sensor data and control commands through a central gateway, thereby minimizing changes to other system components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanism is mounted on all ECUs to enable addition of new drive assist ECUs, then the system can be updated with new functions, but the system complexity and amount of changes required increase significantly
Solution Approach 1:
The patent introduces a gateway as an intermediary device that manages communication between ECUs. The gateway handles the complexity of integrating new drive assist ECUs by acting as a mediator that routes messages and manages data transmission without requiring modifications to existing ECU implementations. This allows new ECUs to be added to the system without increasing overall system complexity.
2Adaptability or versatility
If existing drive assist ECU is replaced with add-on ECU, then new functions can be implemented, but compatibility with existing system infrastructure may be compromised
Solution Approach 1:
The patent implements a universal message bus communication protocol that allows different types of ECUs (existing drive assist ECUs and new add-on ECUs) to communicate using the same standardized interface. The gateway provides universal routing capabilities that work with various ECU types, ensuring that new functions can be implemented while maintaining compatibility with the existing system infrastructure through standardized communication protocols.

AI summary
A control system 9 according to the present invention is mounted on a moving object. The control system 9 includes: an observing device 92 which transmits observation result data indicating an observation result of surroundings of the moving object; a first control instruction device 91 which transmits first control data indicating the control contents determined based on the observation result data; a movement control device 93 which controls movement of the moving object; and a relay device 95 which relays the first control data transmitted from the first control instruction device 91, to the movement control device 93. When a second control instruction device 94 which transmits second control data indicating the control contents determined based on the observation result data is provided to the control system 9, the relay device 95 transmits the second control data instead of the first control data, to the movement control device 93.
