Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing in-vehicle network systems require manual, individual adjustments for adding or changing ECUs, lacking flexibility in accommodating changes or additions.
Innovation Solution
An in-vehicle device with a communication unit to receive setting information and a setting unit to perform operation settings based on this information, allowing easy adaptation to the vehicle's network configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual individual adjustments are performed for adding or changing ECUs, then the system maintains stability, but the adaptability and ease of operation deteriorate
Solution Approach 1:
The in-vehicle device automatically performs role setting and operation configuration by receiving setting information from a management device via communication unit. The setting unit then automatically applies these settings without requiring manual intervention, allowing the system to configure itself based on received parameters such as ECU identifiers, communication protocols, and functional roles.
Solution Approach 2:
The management device prepares setting information in advance that contains all necessary configuration parameters for the in-vehicle device's role in the network. This preliminary preparation of configuration data allows the in-vehicle device to be quickly adapted when added or modified, eliminating the need for time-consuming manual individual adjustments at the dealer level.
2Reliability
If vehicle information cartridges are changed or added to accommodate new ECUs or functions, then the system maintains reliability, but the device complexity and ease of manufacture worsen
Solution Approach 1:
The management device serves multiple functions: it stores setting information for various ECU configurations, generates appropriate role settings based on received information, and distributes configurations to multiple in-vehicle devices. This universal approach eliminates the need for separate vehicle information cartridges for different configurations, as all settings can be managed centrally.
Solution Approach 2:
The management device acts as an intermediary between the configuration management process and the in-vehicle devices. It receives various types of input information about ECU additions or modifications, processes this information to determine appropriate role settings, and then transmits the processed setting information to the relevant devices, simplifying the overall system architecture.
3Manufacturing precision
If individual settings are performed at the dealer level, then the system maintains manufacturing precision, but the productivity and loss of time worsen
Solution Approach 1:
The system employs a feedback mechanism where the management device receives information about ECU additions, modifications, or deletions, processes this feedback information to determine appropriate role settings, and then automatically updates the affected devices. This closed-loop approach ensures configuration precision is maintained while eliminating manual intervention requirements.
Solution Approach 2:
The patent replaces the mechanical process of manual configuration at the dealer level with an automated electronic information processing system. The management device electronically transmits setting information to in-vehicle devices, substituting the manual mechanical adjustment process with automated digital communication and configuration application.
