Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If each vehicle determines its own driving strategy decisions based on onboard sensor data and maps, then vehicle autonomy is achieved, but traffic inefficiencies occur
Solution Approach 1:
The system implements feedback by having vehicles report sensor data and driving decisions to a central server, which processes this information and sends back optimized driving instructions. This closed-loop feedback mechanism allows individual vehicle autonomy to be coordinated with overall traffic efficiency, resolving the contradiction between vehicle independence and traffic optimization.
Solution Approach 2:
The patent merges individual vehicle decision-making with centralized traffic management by combining onboard vehicle sensors and processors with a central server that aggregates data from multiple vehicles. This integration allows the system to maintain vehicle autonomy while achieving coordinated traffic flow optimization that improves overall productivity.
2Device complexity
If vehicles use offline sensor data and map information for driving decisions, then system complexity is reduced, but real-time information is lacking
Solution Approach 1:
The system performs preliminary actions by pre-processing sensor data and map information onboard vehicles, then supplements this with real-time updates from the central server. This approach maintains the benefits of offline processing while ensuring vehicles have access to current traffic conditions, incidents, and dynamic environmental data without excessive complexity.
Solution Approach 2:
The central server acts as an intermediary that bridges onboard vehicle systems with real-time external data. It aggregates information from multiple sources including traffic sensors, weather services, and other vehicles, then delivers processed real-time information to individual vehicles, reducing the information loss without requiring each vehicle to directly access all data sources.
3Reliability
If autonomous driving instructions are provided based on current traffic and incident data, then driving safety is improved, but information processing requirements increase
Solution Approach 1:
The system segments information processing between onboard vehicle systems and the central server. Vehicles perform local processing of sensor data for immediate safety responses, while the server handles aggregate data processing for comprehensive traffic analysis and route optimization. This segmentation improves driving safety through better information availability without concentrating all processing complexity in one location.
Data Source
AI summary
Current data for a geographic area is accessed. The current data comprises at least one of (a) current traffic data for the geographic area, (b) current incident data for the geographic area, or (c) current weather data for the geographic area. Based on the current data, autonomous driving instructions are determined for the geographic area. A notification comprising the autonomous driving instructions is provided such that the notification is received by a vehicle apparatus located within the geographic area or expected to enter the geographic area based on a route being traversed by a vehicle corresponding to the vehicle apparatus. The vehicle apparatus is onboard the vehicle and is configured to control the vehicle in accordance with the autonomous driving instructions.
