Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If GPS data alone is used for navigation, then the system remains simple, but situational awareness is insufficient
Solution Approach 1:
The patent combines multiple information sources (real-time GPS data, crowdsourced data from other vehicles, and predetermined route information) into a unified complexity assessment system. The processor integrates these diverse data streams to generate comprehensive situational awareness, resolving the contradiction by merging information sources rather than relying on GPS alone.
Solution Approach 2:
The system performs multiple functions: acquiring real-time GPS data, receiving crowdsourced information from telematics units, storing predetermined route data, and processing all this information to generate complexity values. This multi-functional approach enables comprehensive situational awareness while managing system complexity through integrated processing.
2Measurement precision
If real-time data processing is implemented, then situational complexity assessment is improved, but computational load increases
Solution Approach 1:
The system stores predetermined route information and complexity thresholds in advance in memory. By having this data pre-prepared and organized, the processor can perform real-time comparisons and assessments more efficiently, reducing the computational load during actual navigation while maintaining high assessment accuracy.
3Reliability
If multiple data sources are integrated, then navigation reliability is improved, but system complexity increases
Solution Approach 1:
The processor acts as an intermediary that receives and standardizes data from multiple sources (GPS unit, telematics control units, memory storage). It processes this diverse information through unified algorithms to generate complexity values, mediating between heterogeneous data sources and the navigation system to maintain reliability while managing complexity.
4Reliability
If complexity thresholds are set low, then driver safety is improved, but false alerts increase
Solution Approach 1:
The system uses predetermined complexity value thresholds stored in memory that can be configured at different levels. By adjusting these threshold parameters, the system balances driver safety with alert accuracy - higher thresholds reduce false alerts while lower thresholds enhance safety monitoring, allowing flexible adaptation to different operational requirements.

AI summary
A vehicle includes an on-hoard satellite navigation device, a telematics control unit, a non-transitory computer readable medium, and a processor. The on-board satellite navigation device is in communication with a global positioning system unit to acquire real-time information regarding conditions near the vehicle's vicinity. The telematics control unit is in wireless communications to a cloud services or a vehicle network to upload and receive crowdsourced information regarding conditions near the vehicle's vicinity. The non-transitory computer readable medium stores predetermined information regarding conditions near the vehicle vicinity. The processor is programmed to output one or more complexity values related to the vehicle's vicinity during vehicle travel based on one or more of the real-time information, the crowdsourced information and the predetermined information.
