Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If driver assistance functions are provided based on fixed map data, then the system structure is simple, but the system cannot reflect changing traveling conditions such as road constructions or surrounding building changes
Solution Approach 1:
The patent transforms static map data into dynamic data structures that can be updated in real-time. The server device receives position information and driver assistance function usage data from mobile objects, statistically processes this information, and embeds updated statistical information into map data. This allows the system to adapt to changing traveling conditions such as road constructions or surrounding building changes while maintaining a relatively simple overall system structure through centralized processing.
2Measurement precision
If statistical processing is performed to reflect real-time traveling conditions, then the accuracy of driver assistance is improved, but the processing time and computational load increase
Solution Approach 1:
The server device continuously receives position information and driver assistance function usage data from mobile objects and performs statistical processing in real-time. The system maintains continuous updates of map data with the latest statistical information, ensuring that driver assistance accuracy is always based on current traveling conditions without requiring periodic batch processing, thus reducing overall processing time delays.
Solution Approach 2:
The system implements a feedback loop where position information and driver assistance function usage data from mobile objects are statistically processed and fed back into the map data. This continuous feedback mechanism allows the system to learn from actual usage patterns and update its understanding of traveling conditions, improving accuracy while managing processing time through efficient statistical methods.
3Reliability
If map data is updated with statistical information from multiple mobile objects, then the reliability of driver assistance is improved, but the data management complexity increases
Solution Approach 1:
The server device merges position information, driver assistance function usage data, and statistical processing results into a unified map data structure. By combining multiple data sources and processing them centrally, the system improves the reliability of driver assistance functions while managing data management complexity through a consolidated approach rather than distributing complex data handling across multiple components.

AI summary
A server device capable of creating data for reflecting traveling conditions that change over time in driver assistance function, an information processing method, an information processing program, and a storage medium are provided. It includes a server communication unit (211) configured to acquire, from a mobile object communication unit (113) arranged at one mobile object (1) of a plurality of mobile objects (1), information to be processed in which position information of the one mobile object is associated with information indicating a driver assistance function being used by the one mobile object, and a processing unit (212) configured to execute statistical processing with respect to the information to be processed acquired by the server communication unit (211) and embed, into the map data, statistical information indicating whether the driver assistance function should be performed or not in a position or area in a map indicated by the map data.
