Vehicle Terminal Route Synchronization with Mobile Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional map guide services require a separate navigation terminal in vehicles, which must be demounted for updates, and lack a convenient method to share routes discovered on a mobile terminal with the vehicle's terminal.
Innovation Solution
A system comprising a vehicle terminal, a mobile terminal, and a telematics multimedia system (TMS) server that synchronizes and compares route information to determine an optimum route, regenerates route link information, and transmits GPS-based route information for efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate navigation terminal is installed in the vehicle, then route guidance functionality is provided, but the terminal must be demounted for updates and requires a separate holder
Solution Approach 1:
The patent merges the navigation functionality with the mobile terminal that the user already possesses, eliminating the need for a separate navigation terminal installation. The mobile terminal's processor executes navigation instructions to provide route guidance, combining the navigation function with an existing device the user carries.
Solution Approach 2:
The mobile terminal serves multiple functions including communication, entertainment, and navigation. By utilizing the mobile terminal's existing processor and display for navigation purposes, the system eliminates the need for dedicated navigation hardware while providing comprehensive route guidance functionality.
2Reliability
If route information is shared between mobile terminal and vehicle terminal, then route optimization is improved, but data transmission and synchronization complexity increases
Solution Approach 1:
The vehicle terminal acts as an intermediary that receives route information from the mobile terminal, processes it by comparing with real-time traffic data, and generates optimized navigation instructions. This intermediary role simplifies the data exchange by establishing a clear communication interface between the mobile terminal and the vehicle's navigation system.
Solution Approach 2:
The system performs preliminary route planning on the mobile terminal before the vehicle journey begins. The route information is pre-processed and then transmitted to the vehicle terminal, which further optimizes it by comparing with current traffic conditions. This preliminary action reduces the computational burden during actual navigation.
