Navigation System Automatic Mode Switching for Server Outages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In navigation systems where both in-vehicle devices and mobile devices provide navigation functions, users face complications when the mobile device loses communication with the server system, requiring users to switch modes and re-set destinations manually, leading to failed route settings and loss of original route guidance.
Innovation Solution
A navigation system with an in-vehicle device and a mobile device that includes a state detector to switch between operation modes automatically, allowing the in-vehicle device to handle route settings when the mobile device cannot connect to the server, ensuring seamless navigation even in poor communication environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the navigation client function of the mobile device is used from the navigation device, then the user can access navigation functions through the mobile device interface, but the system becomes vulnerable to communication failures with the server system
Solution Approach 1:
The patent introduces a mode switching mechanism that acts as an intermediary between the mobile device's navigation client function and the in-vehicle navigation function. When communication failure is detected, the system automatically switches from the mobile device-based navigation client mode to the in-vehicle navigation function mode, ensuring continuous reliable operation without requiring user intervention.
2Adaptability or versatility
If the mobile device is used for navigation client function, then users can leverage mobile device capabilities, but complicated operations are required when server communication fails
Solution Approach 1:
The patent implements an automatic mode switching mechanism that detects communication status and autonomously switches between navigation functions. The system monitors server communication status and automatically transitions from the mobile device navigation client mode to the in-vehicle navigation function mode when communication fails, eliminating the need for users to manually switch modes or perform complicated operations.
3Adaptability or versatility
If the navigation client function is used, then flexible navigation access is provided, but route guidance may be lost when communication fails
Solution Approach 1:
The patent prepares for communication failures by implementing a mode switching mechanism that detects communication status in advance and automatically switches to the in-vehicle navigation function mode when server communication is lost. This pre-prepared switching capability ensures continuous route guidance without interruption or loss, maintaining stable navigation service under varying communication conditions.

AI summary
When an instruction to start a setting operation for a destination is provided by a user during a period in which a navigation server is not available for a mobile device while a navigation function, which uses the navigation server providing distribution function of map data and route search function, of the mobile device is being utilized in a navigation device, the navigation function provided in the navigation device itself is activated and is caused to perform destination setting operation.
