Vehicle Navigation Display Switching for Obstructed Forward Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head-up display systems fail to provide an intuitive and easy-to-understand display of a planned driving route when the real view is obstructed, such as by another vehicle, making it difficult for the observer to grasp the route guidance.
Innovation Solution
A display control device that utilizes a first display area overlapping with the real view and a second display area not overlapping with the real view to present a real-view following navigation image and a bird's-eye-view navigation image, respectively, adjusting their visibility and position based on visibility and weather information to maintain route guidance even when the real view is obscured.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a real-view following navigation image is displayed to guide the driving route, then the route guidance is provided in an easy-to-understand manner by harmonizing with the real view, but the navigation image becomes hidden or difficult to visually recognize when obstructed by other vehicles
Solution Approach 1:
The navigation display is segmented into two distinct views: a real-view following navigation image that harmonizes with the real view for easy understanding, and a bird's-eye-view navigation image that provides reliable route information from above. This segmentation allows each view to serve its specific purpose while compensating for the other's limitations.
Solution Approach 2:
The bird's-eye-view navigation image acts as an intermediary that provides reliable route guidance when the real-view following navigation image is obscured. It mediates between the need for easy understanding and the need for reliable visibility by offering an alternative perspective that is not blocked by other vehicles.
2Reliability
If a bird's-eye-view navigation image is displayed to provide reliable route information, then the route guidance remains visible even when obstructed, but the ease of understanding the route in relation to the real view is reduced
Solution Approach 1:
The system merges two different navigation views (real-view following and bird's-eye-view) into a single navigation system. This combination allows the system to leverage the strengths of both views: the real-view following provides contextual understanding while the bird's-eye-view ensures reliable visibility.
Solution Approach 2:
The navigation system dynamically switches between or combines different display modes based on visibility conditions. When the real view is obstructed, the system activates the bird's-eye-view to maintain reliable guidance, and may adjust the display to harmonize the different views for continued ease of understanding.
3Ease of operation
If the display area overlaps with the real view to provide contextual navigation, then the navigation image harmonizes with the real view, but the navigation image cannot be displayed when the real view is obstructed by other vehicles
Solution Approach 1:
The system transitions from a two-dimensional real-view following display to a three-dimensional bird's-eye-view display that looks down on the vehicle and route. This dimensional change allows the navigation to be displayed from a perspective that is not obstructed by other vehicles, maintaining adaptability while preserving ease of understanding through spatial context.

AI summary
The present invention provides a display in which it is easy to ascertain a planned travel path. This display control device displays, in a first display region, a real-view-following navigation image that follows a specific superimposition target in a real view so as to maintain the positional relation with the specific superimposition target. When it is inferred that visibility in a forward view from a vehicle will be impaired, the display control device displays, in a second display region that has a vertical center which is disposed lower than the vertical center of the first display region, a bird's-eye-view navigation image which includes, in a diagonal view from above, at least a map image that is of the surrounding area of the vehicle and a path image that overlaps with the map image and that indicates a planned travel path.
