Route Transfer Between Telematics and Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems often fail to provide convenient and accessible route guidance for users who need directions to specific locations, especially those not easily accessible by motor vehicles, such as campgrounds or particular stores within malls.
Innovation Solution
A method and system that provide a route with at least first and second portions, using a telematics unit to determine a route status and send the second route portion to a mobile communication device, enabling dynamic navigation adjustments based on the user's location and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If route guidance is provided only through a fixed navigational device (automobile-based or hand-held), then the device structure remains simple, but the adaptability to different user scenarios and locations is reduced
Solution Approach 1:
The patent implements multi-functionality by enabling the navigation system to operate across multiple device types (automobile-based navigational systems and hand-held navigational devices) and serve different user scenarios (driving directions, hiking directions to campgrounds, shopping directions to malls and stores). The system can provide route guidance regardless of which device the user employs, making it universally applicable to various navigation needs and device configurations.
2Ease of operation
If the entire route is provided at once, then the navigation process is straightforward, but the user cannot easily switch between different devices during the journey
Solution Approach 1:
The patent applies segmentation by dividing the complete route into multiple route portions. The system provides a first route portion initially and reserves additional route portions for later transfer. This segmentation allows the user to start navigation on one device and seamlessly switch to another device mid-journey, receiving the next route portion on the new device without interruption to the overall navigation process.
Solution Approach 2:
The system performs preliminary action by pre-calculating and reserving multiple route portions before the user begins navigation. The complete route is segmented and prepared in advance, enabling quick transfer between devices during the journey without requiring recalculation or causing delays. The route portions are ready for immediate transmission when device switching occurs.
3Adaptability or versatility
If navigation is designed for motor vehicle access only, then the system requirements are simplified, but the coverage of accessible locations is limited
Solution Approach 1:
The patent extends universality to location coverage by enabling the navigation system to provide directions to diverse destination types beyond motor vehicle accessibility. The system can guide users to locations such as campgrounds requiring hiking access or specific stores within malls requiring pedestrian navigation. This multi-functional capability allows a single system to serve both vehicle-based and pedestrian-based navigation needs, significantly expanding the coverage of accessible locations.

AI summary
A method for navigation includes providing a route, including at least first and second route portions, at a telematics unit and determining a route status. The method further sends the second route portion to a mobile communication device based on the route status.
