Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple vehicle functions are automated with customizable sequences, then driver workload is reduced and productivity increases, but system complexity and difficulty of detecting and measuring increase
Solution Approach 1:
The system segments vehicle automation into modular function sequences, where each sequence represents a discrete set of automated actions (e.g., parking sequence, security sequence). This segmentation allows the complex automation system to be divided into manageable, independently configurable units, reducing overall system complexity while maintaining high productivity benefits.
Solution Approach 2:
The system implements dynamic configurability of vehicle function sequences, allowing users to customize, activate, or deactivate specific sequences based on varying driving situations and preferences. This dynamic approach enables the system to adapt to different scenarios without requiring a complete redesign of the automation architecture, balancing complexity with flexibility.
2Reliability
If vehicle functions are fixedly predefined by the manufacturer, then reliability is maintained, but adaptability and ease of operation deteriorate
Solution Approach 1:
The system performs preliminary configuration of vehicle function sequences during manufacturing with default reliable settings, while simultaneously preparing the infrastructure for user customization. This preliminary action ensures baseline reliability is maintained while enabling future adaptability through user-defined modifications.
Solution Approach 2:
The system incorporates feedback mechanisms that monitor the execution of vehicle function sequences and provide information about system state and performance. This feedback enables the system to maintain reliability by detecting issues and adapting to actual usage patterns, while also supporting customization as users refine sequences based on observed performance.
3Reliability
If comprehensive checks of predefinable sequences are implemented, then reliability improves, but device complexity and ease of operation worsen
Solution Approach 1:
The system implements self-service validation where the automated execution infrastructure automatically performs checks and validations of vehicle function sequences without requiring manual intervention. The system self-verifies sequence correctness, detects conflicts, and ensures reliable execution, maintaining high reliability while avoiding the complexity of manual validation processes.
4Ease of operation
If repetitive manual actions are required, then ease of operation is maintained for simple systems, but productivity and driver comfort deteriorate
Solution Approach 1:
The system merges multiple individual vehicle functions into consolidated sequences that execute automatically. For example, a parking sequence combines gear shifting, brake activation, and door locking into a single automated routine. This merging eliminates repetitive manual actions, significantly improving driver efficiency and comfort while maintaining operational simplicity through intuitive sequence selection.

AI summary
A system and/or method include receiving vehicle function sequence schemas, which specify a sequence of vehicle functions in the presence of a triggering event linked to the particular vehicle function sequence schema, checking the received vehicle function sequence schemas, storing the checked vehicle function sequence schemas, and checking the presence of a triggering event, selecting a stored vehicle function sequence schema linked to the present triggering event, generating control signals for controlling vehicle function devices according to the selected vehicle function sequence schema, and outputting the generated control signals to the vehicle function devices.
