Head-Up Display Lane Overlay for Intuitive Driving Assist Status
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driving assistance systems, such as lane departure warning and lane keeping assist devices, face challenges in intuitively communicating their active state to drivers, especially when lane markings are unclear or absent, leading to confusion about the system's operational status.
Innovation Solution
An image processing device generates a display image that superimposes virtual elements on the windshield, with these elements changing position and inclination relative to detected lane markings, creating a visual representation that indicates the system's active state by simulating movement and alignment with the lane markings, enhancing driver recognition of the system's operational status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a pattern is displayed on the display device to indicate the active state of the driving assistance device, then the active state can be notified to the driver, but the driver cannot intuitively recognize the active state
Solution Approach 1:
The patent creates a virtual copy of the lane marking that mirrors the real lane marking's position, shape, and movement. This virtual lane marking is displayed on the head-up display device to indicate the active state of the driving assistance device. By copying the visual characteristics of the real lane marking, the system provides intuitive recognition for the driver, resolving the contradiction between information transmission and ease of recognition.
Solution Approach 2:
The patent makes the virtual lane marking dynamic by causing it to move and change position in response to the vehicle's actual movement and the detected lane marking's position. The virtual lane marking dynamically adjusts its inclination and position to match the real lane marking, providing continuous intuitive feedback to the driver about the system's active state and the vehicle's relative position to the lane.
2Device complexity
If the display element position is fixed, then the display device structure is simple, but the display element cannot change position in conjunction with positional information changes
Solution Approach 1:
The patent implements a dynamic display system where the virtual lane marking's position, shape, and inclination are continuously adjusted based on detected positional information. The system calculates the relative position between the vehicle and the lane marking, then dynamically repositions the virtual lane marking on the head-up display to reflect this information, enabling adaptability without requiring complex manual reconfiguration.
Solution Approach 2:
The patent establishes a feedback loop where the display element's position is continuously updated based on detected lane marking position and vehicle position. The system monitors the relative position information and automatically adjusts the virtual lane marking's display position accordingly, creating an adaptive system that responds to changing conditions without increasing structural complexity.
3Device complexity
If the display element is displayed as a flat pattern, then the display is simple, but the display element cannot visually represent the inclined relationship toward the vehicle from the lane marking
Solution Approach 1:
The patent adds a dimensional aspect to the display element by rendering the virtual lane marking with visual characteristics that suggest three-dimensional spatial relationships. The display element is designed to visually represent the inclined relationship between the vehicle and the lane marking by adjusting its orientation and perspective, providing spatial information without requiring complex three-dimensional display hardware.
Solution Approach 2:
The patent changes the visual parameters of the display element, such as its orientation angle, perspective, and shape, to represent the spatial relationship between the vehicle and the lane marking. By dynamically adjusting these parameters based on detected positional information, the system conveys inclined relationship information while maintaining a relatively simple display structure.

AI summary
An image processing device applied to a driving assistance system, which includes: a driving assistance device that detects a relative position of a lane marking with respect to a vehicle and assists a driving of the vehicle based on a detected positional information; and a head-up display device that projects a display image on a projection area arranged on the vehicle to visually recognize a virtual image of the display image, includes: an acquisition device that acquires the positional information; and a generation device that generates the display image including a predetermined display element. The generation device generates the display image to visually recognize the display element at a position associated with the positional information and to visually recognize the display element as a shape inclined toward the vehicle from the lane marking.
