Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated vehicles are used to test automated driving functions, then testing capability is provided, but safety and effectiveness cannot be ensured
Solution Approach 1:
The patent introduces target robots as intermediary objects between test vehicles and the testing environment. These target robots serve as controlled mediators that enable safe collision testing while maintaining testing effectiveness. The target robot acts as a buffer that allows automated driving functions to be tested under controlled conditions without compromising safety.
Solution Approach 2:
The patent creates simplified copies or representations of real-world collision scenarios through target robots. Instead of testing with actual vehicles in uncontrolled environments, the system uses target robots that replicate essential collision dynamics in a controlled manner, preserving testing validity while enhancing safety.
2Adaptability or versatility
If traditional testing methods are used, then simplicity is maintained, but comprehensive testing of automated driving functions is not achieved
Solution Approach 1:
The patent creates a universal testing framework where the ARTS system can perform multiple types of automated driving function tests through a single integrated platform. The system accommodates various test scenarios (collision avoidance, emergency braking, lane changing) using common infrastructure components, making the complex system versatile and adaptable to different testing needs.
Solution Approach 2:
The patent divides the testing system into modular segments including test vehicles, target robots, positioning systems, and communication networks. This segmentation allows each component to be independently developed, tested, and configured for specific testing requirements, managing overall system complexity through modular architecture.
3Reliability
If coordinated robotic control is implemented, then collision safety is improved, but system complexity increases
Solution Approach 1:
The patent merges multiple control functions (positioning, navigation, collision detection, and emergency response) into an integrated coordinated control system. By combining these functions into a unified control architecture, the system manages complexity while achieving comprehensive collision safety through centralized coordination of all robotic units.
Solution Approach 2:
The patent implements continuous feedback loops where positioning systems monitor the locations of test vehicles and target robots, communication networks transmit real-time status information, and the control system adjusts trajectories and speeds based on this feedback. This closed-loop control ensures collision safety while managing system complexity through automated decision-making.
