Vehicle Navigation System with External Traffic Rule Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems do not adequately account for vehicle-specific information when planning routes, leading to suboptimal navigation and potential safety issues due to unconsidered traffic rules related to vehicle characteristics.
Innovation Solution
A system and method that utilize an external management unit to store and assign traffic rules based on vehicle information, including vehicle identification numbers, to a calculation module for route planning, ensuring that navigation information is tailored to the specific vehicle, including restrictions on road usage based on vehicle features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If navigation systems use general route planning without vehicle-specific information, then route calculation is simple and fast, but route compliance with traffic regulations is poor
Solution Approach 1:
The patent introduces an external management unit as an intermediary between the navigation system and traffic regulation databases. This external unit stores vehicle-specific traffic rules and provides them to the navigation system when needed, allowing the navigation device to comply with vehicle-specific regulations without permanently storing large amounts of data or complex validation logic locally.
Solution Approach 2:
The system performs preliminary actions by pre-storing vehicle-specific traffic rules in an external management unit before route calculation. When a vehicle requests navigation, the system retrieves applicable traffic rules for that specific vehicle type in advance, ensuring compliance is built into the route planning process from the beginning rather than checking during route execution.
2Adaptability or versatility
If navigation systems store vehicle information locally, then route planning can consider vehicle characteristics, but data storage requirements and update complexity increase
Solution Approach 1:
The patent extracts vehicle-specific traffic rule data from the navigation device and stores it in an external management unit. This separation allows the navigation system to remain lightweight while still accessing vehicle-specific regulations when needed. The external unit handles data storage and updates, freeing the navigation device from data management complexity.
Solution Approach 2:
The external management unit serves multiple functions: it stores vehicle-specific traffic rules for different vehicle types, provides this data to various navigation systems, and updates regulations centrally. This multi-functional external unit benefits all navigation users without requiring each device to have its own complete database.
3Reliability
If navigation systems retrieve traffic rules in real-time, then route compliance is improved, but data transmission time and network dependency increase
Solution Approach 1:
The system performs preliminary retrieval of vehicle-specific traffic rules and stores them in the external management unit before actual route calculation is needed. When a user requests navigation, the applicable rules are already available in the external unit, allowing fast retrieval without real-time network delays during the routing process itself.

AI summary
The invention relates to a system and method for navigating a vehicle, having a managing unit (server) arranged outside of the vehicle for centrally storing traffic information and traffic rules relating to vehicle information, said traffic rules relating in particular to the blocking of streets, and a detection unit which has an interface for detecting vehicle information of the vehicle, said vehicle information containing at least one vehicle identification number, and which is designed to transmit the detected vehicle information of the vehicle to the managing unit. The system for navigating a vehicle further has a computing module for computing navigation information, said computing module being designed to incorporate traffic rules, which are stored on the managing unit and relate to vehicle information of the vehicle, into the computation of the navigation information. The system also has a navigation unit (client) which is arranged in the vehicle for outputting navigation information computed by the computing module.
