Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cloud-based collision data statistics are generated and utilized, then the accuracy of collision prediction and preparation is improved, but the device complexity and data processing requirements increase
Solution Approach 1:
A central collision data administration device is introduced as an intermediary between crashed vehicles and receiving vehicles. This mediator collects, stores, and processes collision signals from multiple vehicles, then provides analyzed collision data to vehicles that need it, thereby improving prediction accuracy while centralizing the complexity rather than distributing it across all vehicles
Solution Approach 2:
The system creates data copies of collision signals from crashed vehicles and stores them in a centralized database. These copied data can be retrieved and analyzed by multiple receiving vehicles without requiring the original vehicles to remain involved, enabling efficient data sharing and statistical analysis
2Reliability
If collision data from multiple vehicles is compiled and statistically analyzed, then the reliability of safety system adjustments is improved, but the loss of time for data transmission and processing increases
Solution Approach 1:
The collision data administration device pre-processes and stores collision signals as they are received from crashed vehicles, organizing them into ready-to-use formats before any receiving vehicle needs them. This preliminary organization of data reduces the processing time when vehicles need to access collision statistics for safety adjustments
Solution Approach 2:
The system maintains continuous operation of the data administration device, which continuously receives, stores, and makes available collision data without interruption. This continuous availability ensures that receiving vehicles can access data immediately when needed, minimizing delays in safety system adjustments
3Reliability
If safety systems are adjusted based on server-based collision data, then the effectiveness of collision protection is improved, but the ease of operation and system configuration becomes more difficult
Solution Approach 1:
The receiving vehicle's control device automatically retrieves collision data from the administration device and performs self-adjustment of safety systems based on the retrieved data. This automated self-service approach improves protection effectiveness while minimizing the need for manual configuration or complex user intervention
Data Source
AI summary
A method for supplying a collision signal pertaining to a vehicle collision includes: generating a collision signal that represents at least one characteristic of a collision involving at least one crashed vehicle and position data of the collision, using collision-relevant sensor data of the crashed vehicle; and outputting the collision signal via an interface to a central collision data administration device.
