Vehicle Interface Guidance Indication Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle navigation systems fail to update surroundings in real time and cannot effectively display turn-by-turn guidance information through multiple interfaces, leading to driver distraction and limited usability due to narrow bandwidth networks and limited output devices.
Innovation Solution
A vehicle system that includes a communication unit, a vehicle interface, and a controller to receive and decode navigation data, recognize marks and characters, and output guidance information through various interfaces such as the cluster and head-up display, reducing driver distraction and enhancing usability by leveraging phone connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If navigation data is transmitted through the vehicle network (CAN), then the system can receive guidance indication from user equipment, but the narrow bandwidth of the network prevents direct reception of guidance indication
Solution Approach 1:
The system extracts only the essential guidance indication elements (marks and characters) from the navigation data transmitted through the narrow bandwidth network, rather than transmitting the complete navigation data. This extraction approach overcomes the bandwidth limitation by sending only critical information that can be rendered into full guidance indication.
Solution Approach 2:
The controller acts as an intermediary that receives navigation data through the limited bandwidth network, processes it to extract guidance indication, and then outputs it through the vehicle interface. This intermediary processing resolves the contradiction between network bandwidth limitations and the need for complete guidance information.
2Ease of operation
If guidance indication is displayed only through the navigation system, then the system structure remains simple, but driver distraction increases and usability decreases
Solution Approach 1:
The system enables multiple vehicle interfaces (cluster, head-up display, and navigation system) to display guidance indication, rather than limiting it to the navigation system alone. This multi-functionality approach reduces driver distraction by presenting information through multiple channels while maintaining system usability.
Solution Approach 2:
The guidance indication is segmented and distributed across multiple display interfaces based on their capabilities and driver visibility. The cluster and head-up display show critical turn-by-turn information, while the navigation system provides comprehensive navigation data, creating a segmented information distribution that improves ease of operation.
3Loss of information
If the vehicle interface outputs complete navigation data, then all navigation information is available, but driver distraction increases due to excessive information display
Solution Approach 1:
The controller extracts only the essential guidance indication (marks and characters) from the complete navigation data for display on the vehicle interface. This extraction ensures that critical navigation information is conveyed without presenting the full complexity of navigation data, thereby reducing driver distraction while maintaining information completeness.
Solution Approach 2:
Different interfaces display different qualities and types of navigation information based on their characteristics and driver needs. The cluster and head-up display show simplified mark and character information for quick recognition, while the navigation system displays complete navigation data, creating local quality variations that reduce distraction.
Data Source
AI summary
A vehicle and method for controlling the same, enabling guidance indication, such as turn by turn information to be displayed in cooperation with an interface in the vehicle, such as a cluster are provided to minimize driver distraction and increase usability of phone connectivity to guarantee stability and convenience. The vehicle includes a communication unit that receives navigation data from an outside terminal and a vehicle interface that outputs the navigation data. A controller then recognizes at least one of a mark and a character based on the navigation data and operates the vehicle interface to output the at least one of the mark and the character.
