Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a safety envelope is set to ensure comprehensive safety monitoring, then safety coverage is improved, but system complexity increases
Solution Approach 1:
The safety envelope is divided into multiple zones (first safety zone and second safety zone) with different monitoring rules. The first safety zone uses a first rule for monitoring violations, while the second safety zone uses a second rule, allowing complex safety monitoring to be broken down into manageable segments with different complexity levels.
Solution Approach 2:
The system dynamically selects monitoring rules based on the detected situation. When the situation matches a predefined pattern, the corresponding rule is applied; otherwise, a default rule is used. This dynamic adaptation allows the system to maintain high safety coverage while reducing complexity for common scenarios.
2Measurement precision
If multiple monitoring rules are implemented for different situations, then monitoring accuracy is improved, but processing time increases
Solution Approach 1:
Multiple monitoring rules are pre-configured for different situations before runtime. The system has a library of predefined rules (first rule, second rule, etc.) that are prepared in advance, allowing rapid selection and application without requiring complex real-time analysis or rule generation.
Solution Approach 2:
The system uses template-based rule structures that can be replicated and applied to different situations. Once a monitoring rule is defined for a particular situation, similar rules can be copied and adapted for comparable scenarios, reducing the overall processing burden while maintaining comprehensive coverage.
3Measurement precision
If comprehensive detection information is collected, then situation determination accuracy is improved, but data processing load increases
Solution Approach 1:
The system extracts only the necessary detection information required for situation determination rather than processing all available data. By identifying and extracting only the relevant features and parameters needed for safety envelope monitoring, the system achieves accurate situation determination while reducing the overall data processing load.

AI summary
A processing method for performing processing related to driving control of a host vehicle includes: acquiring detection information describing a state detected in a traveling environment of the host vehicle; determining a situation to be monitored for the host vehicle based on the detection information; setting a safety envelope based on the detection information to include defining a physics based boundary, margin, or buffer area around the host vehicle; monitoring a violation of the safety envelope based on a comparison between the safety envelope and a positional relationship between the host vehicle and a target moving object; and determining a rule for setting the safety envelope, which includes a restriction rule to be applied when an application condition is satisfied and a standard rule to be applied when the application condition is not satisfied, based on a determination result of whether the application condition is satisfied.
