Solution Overview
Problem
Existing vehicle control systems face inefficiencies due to optimized circuit designs that are inflexible, requiring significant development time and cost for changes, and result in lengthy and heavy wiring harnesses due to separate controller structures and non-shared signals.
Innovation Solution
A standard controller system with a three-layer structure comprising standard controllers, a gateway controller, and a central computer, allowing components to be added or changed via software updates, with signal classification and standardized interfaces for efficient communication and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If optimized circuit design is used for each controller, then material cost is reduced, but development time and cost increase when circuit modifications are needed
Solution Approach 1:
The patent implements a standardized controller platform that can be universally applied across multiple controllers and functions. The controller uses a common hardware architecture with standardized input/output circuits that can be configured through software rather than requiring physical circuit modifications. This allows the same controller design to serve multiple purposes and be easily adapted to different applications without incurring additional development time or costs.
2Adaptability or versatility
If separate controller structures are used for different functions, then each controller is optimized for its specific function, but wiring harness length and weight increase
Solution Approach 1:
The patent merges multiple separate controller functions into a unified standardized controller platform. Controllers with different functions share a common hardware architecture, communication protocols, and physical interface standards. This consolidation reduces the number of separate controllers needed and consequently reduces the overall wiring harness length and weight while maintaining functional optimization through software configuration.
Solution Approach 2:
The standardized controller is designed to perform multiple functions through software configuration rather than requiring separate dedicated hardware for each function. This multi-functionality reduces the total number of controllers and their associated wiring, thereby reducing wiring harness weight while maintaining functional specialization through software.
3Adaptability or versatility
If separate controller structures are used for different functions, then each controller is dedicated to its function, but signal sharing between controllers becomes difficult
Solution Approach 1:
The standardized controller platform enables signal sharing between different functional controllers through common communication protocols and standardized interfaces. All controllers use the same signal definitions, communication standards, and data formats, allowing signals to be easily shared and reused across multiple functions without increasing system complexity.
4Quantity of substance
If circuit optimization is performed for each controller, then material cost is reduced, but flexibility to add or change components decreases
Solution Approach 1:
The standardized controller uses a universal hardware platform with configurable software that allows components to be added or changed without requiring circuit redesign. The same optimized circuit design can be reused across multiple applications, and component changes are achieved through software configuration rather than hardware modification, maintaining both cost efficiency and flexibility.
