Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tests are performed in an actual testing course, then the vehicle can detect information in a real running state, but the surrounding environment varies each time making it difficult to achieve high reproducibility
Solution Approach 1:
The patent creates a virtual copy of the surrounding environment using pre-recorded video and audio data from actual road conditions. This copied environment is displayed on screens positioned to simulate the driver's field of view, allowing repeated testing under identical conditions without requiring actual road traversal each time.
Solution Approach 2:
The testing system separates the vehicle into independent functional components: the actual vehicle body, the virtual environment projection system, and the measurement apparatus. This segmentation allows the environment to be reproduced independently through video playback while the vehicle remains stationary or moves on a controlled track.
2Adaptability or versatility
If the vehicle is moved to different locations for testing, then various running conditions can be evaluated, but the test conditions cannot be maintained consistently across different times
Solution Approach 1:
The system pre-recordings environmental data (video and audio) from actual driving conditions before testing. These pre-captured environments are then replayed during tests, allowing the same running conditions to be reproduced consistently across multiple test sessions without requiring the vehicle to be transported to different locations.
3Adaptability or versatility
If simulation is used to reproduce nearby vehicle behavior, then various road surface conditions can be simulated, but it is difficult to evaluate actual vehicle detection capability
Solution Approach 1:
Instead of using mathematical simulations of vehicle behavior, the system copies actual sensor data and video footage from real driving scenarios. This copied real-world data is presented to the vehicle's detection systems, enabling accurate evaluation of detection capability while maintaining the variety of road conditions found in actual driving.
