Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If extensive verification and correction of control programs and data is performed to improve the degree of completion of the front lamp control apparatus, then the reliability of the control system is improved, but the development time and man-hours increase enormously
Solution Approach 1:
The patent applies preliminary action by performing verification and correction of control programs and data before actual vehicle deployment. The simulation system allows developers to identify and fix issues in advance, including timing synchronization problems between detection control apparatus and front lamp control apparatus, thereby improving reliability while managing development time through structured pre-testing
Solution Approach 2:
The patent uses a simulation environment that creates virtual copies of the vehicle system, including virtual detection control apparatus and virtual front lamp control apparatus. This copying approach allows extensive verification to be performed on the simulation system before deploying to the actual vehicle, reducing the need for repeated physical testing and thereby reducing development time while maintaining high reliability standards
2Adaptability or versatility
If the front lamp control apparatus is integrated with other control apparatuses in a complex vehicle system, then the functionality and versatility of the system is improved, but the device complexity and difficulty of verification increase
Solution Approach 1:
The simulation system is designed to be universal and multi-functional, capable of simulating not only the front lamp control apparatus but also the detection control apparatus and their interactions. This universal simulation platform can verify various integration scenarios between different control apparatuses, thereby supporting system versatility while managing complexity through a unified verification environment
Solution Approach 2:
The simulation system acts as an intermediary between the detection control apparatus and the front lamp control apparatus during the verification phase. It mediates the interaction between these control apparatuses, allowing their integration to be tested in a controlled virtual environment before actual deployment, thereby reducing the complexity burden during real system integration
3Measurement precision
If multiple verifications and corrections are performed to ensure proper operation of the front lamp control apparatus, then the measurement precision of control performance is improved, but the productivity of the development process decreases
Solution Approach 1:
The patent creates virtual copies of the control apparatuses and their operating environments in the simulation system. Multiple verifications can be performed on these copies without affecting physical hardware, allowing high measurement precision in control performance evaluation while maintaining development productivity through virtual testing
Solution Approach 2:
The simulation system enables preliminary verification of control programs and data before actual vehicle deployment. By performing multiple checks in advance on the simulation platform, the system achieves high verification accuracy while reducing the need for repeated physical testing, thereby improving overall development efficiency
Data Source
AI summary
An evaluation simulation system includes a driver monitor, operation members, a model calculator, a monitor image generator, a camera module, and a detection control apparatus. The driver monitor displays a field-of-view image from a virtual vehicle corresponding to a vehicle. The operation members receive operations performed by a driver. The model calculator executes a model control of the virtual vehicle. The monitor image generator generates the field-of-view image after a movement. The detection control apparatus extracts information regarding a virtual object from a captured image obtained by the camera module, and outputs the information to the front lamp control apparatus. The model calculator generates control output information related to the front lamp control apparatus. The monitor image generator causes the field-of-view image under illumination by the front lamp control apparatus to be displayed.
