Vehicle Navigation System Integrating Smartphone Path Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Navigation devices in vehicles and smartphone navigation apps often provide different path information to the same destination, leading to user inconvenience due to limited smartphone display size and potential communication defects affecting position determination.
Innovation Solution
A navigation device for vehicles that includes a communication module, display, and processor to simultaneously receive and display path information from both the vehicle's navigation system and a user terminal, using modes like picture-in-picture or dual displays to present multiple paths effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If path information is provided only through a smartphone navigation application, then functionality is improved due to rapid updates, but user convenience deteriorates due to limited display size
Solution Approach 1:
The patent merges the navigation functions of the vehicle-mounted navigation device and the smartphone navigation application into a unified system. The processor integrates path information from both devices, allowing users to benefit from the updated functionality of the smartphone app while enjoying the large display capability of the vehicle navigation system. This combination resolves the contradiction by consolidating the advantages of both separate systems.
2Area of stationary object
If path information is provided only through the vehicle navigation device, then display quality is improved, but reliability deteriorates due to potential communication defects affecting position determination
Solution Approach 1:
The system prepares for potential communication failures by establishing a backup mechanism in advance. The processor is configured to receive and process path information from both the vehicle navigation device and the smartphone navigation application simultaneously. This redundancy ensures that if communication defects occur in one system, the other can provide backup path information, maintaining navigation reliability without compromising display quality.
3Reliability
If multiple path information sources are integrated, then reliability is improved through backup mechanisms, but device complexity increases
Solution Approach 1:
The vehicle navigation device's processor is designed to perform multiple functions: it processes path information from its own navigation system, receives path information from the smartphone navigation application via the communication module, and integrates both sources into a unified display. This multi-functionality allows the single device to handle multiple information sources without requiring additional separate systems, thereby improving reliability while controlling complexity.

AI summary
A navigation device for a vehicle includes a communication module for communicating with a user terminal, a display, and a processor for setting a navigation destination, searching a first path toward the navigation destination, receiving second path information corresponding to a second path toward the navigation destination from the user terminal through the communication module, and displaying first path information and the second path information on the display depending on a predetermined display mode.
