Powertrain Domain Control Integration for Software Failure Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The failure of any one of the vehicle control unit (VCU), battery management system (BMS), or motor control unit (MCU) application layer software causes the vehicle to malfunction, as they are not integrated effectively, leading to operational failures.
Innovation Solution
The method involves dividing the component tasks of the vehicle control, battery management, and motor control layers into sub-tasks, determining interface configurations, and integrating them into a powertrain domain control system to minimize dependencies and mutual influence, ensuring independent operation and reducing hardware and development costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the VCU, BMS, and MCU operate independently, then software failure isolation is achieved, but hardware integration and development efficiency are reduced
Solution Approach 1:
The patent introduces a gateway as an intermediary component that mediates communication between the independently operating VCU, BMS, and MCU. The gateway manages data exchange and coordination without requiring direct integration between control units, thus maintaining software failure isolation while enabling necessary system-wide communication and reducing overall system complexity.
2Reliability
If multiple separate control units are used, then software independence is achieved, but hardware costs and development complexity increase
Solution Approach 1:
The patent designs the VCU, BMS, and MCU as standardized modular units with universal communication interfaces and protocols. Each control unit can perform its specific function while also serving as a generic platform that can be configured for different vehicle applications, reducing hardware development costs and simplifying manufacturing through standardized production processes.
