Vehicle Display Control for Road Incline Visual Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems fail to account for inclined road conditions, leading to a sense of strangeness felt by occupants when images are displayed as if the vehicle is on a flat road.
Innovation Solution
A display control device that acquires incline angle information and adjusts images of the vehicle and road to match the actual road incline, using virtual viewpoint adjustments and image tilting to simulate the actual road conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an image as if the vehicle is traveling on a flat road is displayed at the display unit, then the display is simple and straightforward, but the occupant feels a sense of strangeness when traveling on an inclined road
Solution Approach 1:
The display control section changes the display parameters (tilt angle, orientation) of the virtual image based on the detected road incline angle. When the road is inclined, the virtual image is tilted by the same angle as the road, making the display conform to the actual road condition and eliminating the sense of strangeness for the occupant.
2Object-affected harmful factors
If the image is altered to tilt in accordance with incline angle information, then the sense of strangeness is moderated, but the device complexity increases
Solution Approach 1:
Instead of using complex mechanical systems to physically tilt the display unit, the patent uses image processing and virtual rendering techniques. The display control section generates a virtual image that is tilted according to the road incline angle, achieving the same effect as a physical tilt without the mechanical complexity.
3Loss of information
If a virtual viewpoint is used to display the image, then the visualization of road inclination is achieved, but the calculation and processing requirements increase
Solution Approach 1:
The system pre-calculates and stores three-dimensional information data of the road surface in advance. When the vehicle is traveling, the display control section only needs to retrieve the pre-stored data and adjust the virtual viewpoint based on the current incline angle, rather than performing complex real-time calculations, thus reducing processing power requirements.

AI summary
A display control device (28) acquires incline angle information of a road on which the vehicle is traveling. The display control device displays, at a display unit (24, 25, or 26), an image portraying the vehicle and an image portraying the road on which the vehicle is traveling, in which the vehicle is viewed from a virtual viewpoint, by altering the image portraying the vehicle and the image portraying the road so as to be tilted in accordance with the acquired incline angle information.
