Engineering Contradiction Analysis
1Reliability
If multiple simulations are run to test control units, sensing units, and actuating units, then testing completeness and safety validation are improved, but testing time and complexity increase
Solution Approach 1:
The system segments the testing process by creating multiple independent simulation instances that can run in parallel. Each simulation instance tests specific scenarios independently, allowing comprehensive safety validation without sequential execution. The communication module divides simulation data distribution across multiple interfaces, enabling concurrent testing of control units, sensing units, and actuating units.
Solution Approach 2:
The system performs preliminary actions by pre-configuring simulation instances and mapping them to communication interfaces before actual testing begins. The processing unit pre-establishes the mapping between simulation instances and communication module interfaces, so that when testing starts, multiple simulations can immediately run in parallel without setup delays.
2Reliability
If multiple simulations are run to validate operation, then testing thoroughness is improved, but device complexity increases
Solution Approach 1:
The communication module is designed with universal functionality to handle multiple simulation instances simultaneously through a set of interfaces. Each interface can communicate with different simulation instances and vehicle components, making the communication module multi-functional. This universality allows comprehensive operation validation without proportionally increasing overall system complexity.
Solution Approach 2:
The system creates multiple copies of simulation instances that can run independently and in parallel. Each simulation instance is a copy of the testing framework configured for specific scenarios. This copying approach allows thorough validation across multiple scenarios while maintaining a standardized testing structure, preventing complexity from escalating proportionally with the number of simulations.
3Productivity
If parallel testing on multiple vehicles is implemented, then productivity is improved, but communication and coordination complexity increases
Solution Approach 1:
The communication module segments communication tasks by assigning different interfaces to different simulation instances and vehicle components. This segmentation allows parallel testing on multiple vehicles without requiring complex centralized coordination, as each interface independently manages its assigned simulation instance and corresponding vehicle components.
