Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual solutions are used for specific geographic regions and situations, then the system can handle specific contexts well, but the system lacks generalizability and flexibility across different surrounding situations
Solution Approach 1:
The automated driving system is divided into multiple independent function modules, each responsible for a specific subfunction (e.g., longitudinal guidance, transverse guidance, park assist, following assist). Each module has defined validity attributes that specify the surrounding situations in which it is valid. This segmentation allows the system to handle different situations by selectively activating appropriate modules rather than using a single complex monolithic system.
Solution Approach 2:
The system provides a universal framework that can accommodate multiple different function modules through a common architecture. The control system is designed to accept various types of function modules with different validity attributes, allowing the same system structure to handle diverse surrounding situations by simply changing which modules are active, rather than requiring different system designs for different situations.
2Reliability
If automated driving functions are restricted to certain geographic regions with high detail resolution mapping, then the system can operate reliably in those regions, but the system cannot operate in other geographic regions
Solution Approach 1:
The system dynamically selects and activates function modules based on the current surrounding situation and geographic region. The control system continuously evaluates the validity attributes of available modules and activates the appropriate module for the current context. This dynamic adaptation allows the system to operate reliably in different geographic regions by switching between modules with different validity specifications, rather than being statically restricted to pre-defined regions.
3Reliability
If differently designed control systems are used for different situations, then each control system can be optimized for its specific situation, but the overall system becomes complex and difficult to manage
Solution Approach 1:
Multiple differently designed control systems (function modules) are merged into a single unified control system architecture. Instead of having separate control systems for different situations, the patent combines them into one system that contains all function modules with their respective optimizations. The unified control system selects and activates the appropriate module based on the current situation, achieving the benefits of situation-specific optimization without the complexity of managing multiple independent control systems.
