Vehicle Navigation System Wireless Route Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems fail to provide timely and individualized traffic information to drivers outside the vehicle, often resulting in increased fuel consumption, driver stress, and accident risk due to late detection of traffic jams, as information is typically available only once the journey has started and requires driver attention and local knowledge to navigate through.
Innovation Solution
A method and system where a navigation system in the vehicle transmits relevant travel route information wirelessly to a playback device, such as a mobile phone or PDA, allowing the driver to receive optimized departure times and route recommendations based on real-time traffic conditions, reducing the need for complex program structures in the playback device and enabling bidirectional communication for control and service integration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traffic information is made available via radio, RDS, TMC, or Internet, then traffic situation information can be obtained, but the information is available only after the journey has started and it is too late to avoid traffic jams
Solution Approach 1:
The navigation system receives and stores traffic information in advance before the journey starts. The system pre-processes traffic data and prepares route recommendations ahead of time, allowing the driver to make informed decisions about departure timing before entering traffic congestion.
2Loss of information
If comprehensive traffic information covering many routes is provided, then complete traffic situation data is available, but the driver must search and evaluate the information requiring high concentration and local knowledge
Solution Approach 1:
The navigation system extracts only the relevant traffic information for the driver's specific route from the comprehensive traffic data. The system filters out unnecessary information and presents only the essential route-specific traffic conditions, eliminating the need for drivers to search through or evaluate large amounts of data.
Solution Approach 2:
The navigation system automatically evaluates and processes traffic information, generating ready-to-use route recommendations without requiring driver intervention. The system performs the information evaluation task itself, presenting finalized recommendations rather than raw data requiring manual analysis.
3Adaptability or versatility
If the navigation system evaluates and selects traffic information based on the travel route, then individualized relevant information is provided, but complex program structures are required in the playback device
Solution Approach 1:
The navigation system combines the travel route data with traffic information evaluation in a single integrated system. By merging these functions in the navigation system rather than requiring separate capabilities in the playback device, the solution achieves individualized information delivery without increasing playback device complexity.

AI summary
A method for transmitting travel route information to a person present outside of a motor vehicle, and to a system for transmitting such information. The method for transmitting travel route information to a person present outside of a motor vehicle provides that a navigation system present in the motor vehicle wirelessly transmits a data stream including the information to be transmitted directly or indirectly to a display device carried by the person. The information to be transmitted can be perceived by the person by the display device.
