Vehicle Navigation Display Angle Control at Turns and Curves
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current navigation systems in vehicles often confuse users by displaying driving directions based on the forward direction rather than the vehicle's current location, especially at turning points and curved sections, making it difficult to determine the correct driving path.
Innovation Solution
A display device and method for vehicles that activate a navigation mode to display a virtual item indicating the driving direction change at a specific angle relative to the vehicle's current location, adjusting the display angle based on the angle of the driving direction change, ensuring directions are shown relative to the vehicle's position rather than the forward direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the navigation system displays driving direction based on the forward straight direction, then the display is simple and consistent, but the user cannot recognize the actual driving direction at turning points and curved sections
Solution Approach 1:
The patent inverts the conventional approach by not displaying the arrow in the forward straight direction, but rather calculating and displaying it in the actual driving direction based on the vehicle's current location and the road's geometry. This inversion resolves the contradiction by prioritizing accurate direction information over simple consistent display.
Solution Approach 2:
The patent changes the parameter of arrow display angle from a fixed forward direction to a dynamic angle calculated based on the vehicle's current location, road curvature, and turning point information. This parameter change enables the arrow to accurately reflect the actual driving direction while maintaining a consistent display format.
2Device complexity
If the arrow indicates direction on the basis of forward straight direction toward curved road, then the display method is simple, but it confuses the user with regard to the actual driving direction
Solution Approach 1:
The patent performs preliminary calculations of the arrow display angle based on pre-acquired road information and vehicle location data before the user needs the direction information. By pre-calculating the optimal display angle that reflects actual driving direction, the system maintains simplicity while ensuring reliability.
Solution Approach 2:
The patent introduces an intermediary calculation process that mediates between the simple forward direction display and the complex actual direction requirement. The calculated angle serves as an intermediary parameter that transforms the raw road geometry data into a user-friendly arrow display that accurately indicates the actual driving direction.

AI summary
The present disclosure relates to a vehicle display device and a control method thereof, the vehicle display device comprising: a display unit; and a control unit that activates a navigation mode for guiding to a destination, and controls the display unit to display a virtual item indicating a driving direction that needs to be changed at a specific display angle when the driving direction needs to be changed within a preset distance on the basis of road information provided in the navigation mode while a vehicle is driving to the destination, wherein the control unit performs a control such that the display angle of the item changes on the basis of the angle of the driving direction that needs to be changed.
