Driving Support Device Using Drag-and-Drop Vehicle Icons
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automatic driving systems lack intuitive and convenient methods for drivers to instruct specific driving operations, such as lane changes or following traveling, due to non-intuitive switch operations and complex interfaces, making them difficult for a wide range of users to use without training.
Innovation Solution
A driving support device with an image output unit, operation signal input unit, and command output unit that allows users to intuitively instruct driving operations by interacting with a graphical interface, such as dragging and dropping vehicle icons, to control the automatic driving system, enabling commands for following traveling, distance adjustments, and other operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional switch operations are used for automatic driving control, then the system can perform specific driving operations, but the user interface becomes complex and non-intuitive, making it difficult for users to operate without training
Solution Approach 1:
The patent uses graphical icons representing vehicles on a map display as a simplified copy of the actual driving scenario. Users interact with these visual representations by dragging and dropping icons to indicate desired driving operations, replacing complex switch operations with intuitive graphical interactions that mirror the actual spatial relationships in the driving environment
Solution Approach 2:
The patent transitions from one-dimensional switch operations to two-dimensional graphical interactions on a display screen. Users can visually position vehicle icons in spatial relationships (front, rear, left, right) to indicate desired driving operations, adding a spatial dimension to the control interface that makes operations more intuitive and easier to understand
2Ease of operation
If a simplified graphical interface is implemented, then ease of operation improves, but the system must accurately interpret user intentions to maintain reliability
Solution Approach 1:
The system provides visual feedback by displaying the current state of vehicle icons and their positions on the screen. When users drag and drop icons to indicate desired operations, the system processes these positional changes and executes corresponding driving commands, creating a clear feedback loop that confirms accurate interpretation of user intentions while maintaining system reliability

AI summary
In a driving support device, an image output unit outputs an image including a host vehicle object representing a host vehicle and a nearby vehicle object representing a nearby vehicle, to a display unit. The operation signal input unit receives an operation of a user for changing a distance between the host vehicle object and the nearby vehicle object in the image displayed on the display unit. The command output unit outputs a command for instructing one vehicle to travel following another vehicle when the distance between the host vehicle object and the nearby vehicle object is equal to or less than a predetermined distance, to an automatic driving control unit that controls automatic driving.
