Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional manufacturing process of vehicles with domain-based, zone-based, and hybrid architectures is time-consuming, requiring full assembly and on-board network installation before testing and software updates can be performed.
Innovation Solution
A system and procedure for initializing a zone module of a vehicle on-board network, which includes a zone control unit trained to perform a local diagnostic process and a computer device to initiate an initialization process, reducing the need for extensive physical wiring and allowing for flexible and efficient production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional full vehicle assembly is performed before testing and initialization, then complete system integration is achieved, but production time is significantly increased
Solution Approach 1:
The patent enables zone modules to perform self-initialization and local diagnostics before being installed in the vehicle. The zone control unit executes initialization routines autonomously, testing communication with connected components (sensors, actuators, ECUs) in advance. This preliminary action allows the module to be pre-configured and validated independently, eliminating the need to wait until full vehicle assembly is complete before performing critical system checks.
Solution Approach 2:
The patent divides the vehicle's electrical system into independent zone modules, each with its own zone control unit capable of autonomous initialization. This segmentation allows each zone to be tested and initialized separately rather than requiring complete vehicle assembly. The modular approach enables parallel processing of multiple zones and reduces the critical path of the manufacturing process.
2Reliability
If zone modules are initialized after full vehicle assembly, then complete system context is available, but manufacturing flexibility is reduced
Solution Approach 1:
The zone control unit performs initialization and local diagnostics autonomously before installation. It can test communication protocols, validate component connections, and configure parameters in advance without requiring the complete vehicle context. This preliminary configuration maintains manufacturing flexibility while ensuring the module is ready for integration.
Solution Approach 2:
The zone module is designed with self-initialization capabilities, where the zone control unit autonomously executes diagnostic routines and configuration tasks. The module serves itself by testing its own components and establishing communication protocols without requiring external vehicle systems to be fully assembled or configured first.
3Reliability
If extensive physical wiring is used for domain-based architecture, then system functionality is achieved, but cabling complexity increases
Solution Approach 1:
The zone control unit serves multiple functions: it acts as a domain controller for its specific zone, performs local diagnostics, executes initialization routines, and manages communication with multiple types of components (sensors, actuators, ECUs). This multi-functionality reduces the need for separate dedicated wiring for each function, as a single zone-based architecture handles diverse communication needs.
Solution Approach 2:
The patent implements a zone-based architecture that segments the vehicle's electrical system into spatially-defined zones, each with its own control unit. This segmentation replaces the traditional domain-based functional grouping with location-based grouping, reducing cabling complexity by allowing each zone to manage its local components independently rather than requiring extensive cross-domain wiring throughout the vehicle.
