Vehicle Head-Up Display Correction for Disturbance-Stable Object Cues
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern head-up display systems in vehicles face instability in visual output due to sudden vehicle movements and vibrations, leading to incorrect positioning of external object information, which can compromise driver safety.
Innovation Solution
A computer-implemented method and system that monitors the driver's eye position and external objects using camera systems and sensors, detects disturbances, and adjusts the display location to maintain a stable visual output on the head-up display, ensuring accurate positioning and highlighting of external objects despite vehicle movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spatial information is displayed on the head-up display without correction, then the display shows object information, but the visual output becomes unstable due to vehicle vibrations and movements
Solution Approach 1:
The system performs preliminary actions by detecting disturbance events (vehicle vibrations and movements) before they significantly affect the display stability. The correction module continuously monitors for disturbances and applies corrections in advance to maintain stable visual output, preventing instability rather than reacting to it after occurrence.
Solution Approach 2:
The system implements feedback by continuously monitoring the relationship between the head-up display, windshield, and driver's eyes, detecting when vehicle movements cause misalignment, and automatically applying corrections to the display parameters. This closed-loop feedback mechanism ensures the visual output remains stable despite external disturbances.
2Reliability
If the display location is adjusted frequently to compensate for vehicle movements, then the visual output stability improves, but the response time and processing speed decrease
Solution Approach 1:
The system applies dynamic correction by continuously adjusting display parameters based on real-time detection of vehicle movements and driver eye position. Rather than fixed corrections, the system dynamically adapts the display location and characteristics to maintain stability while responding efficiently to changing conditions, optimizing both stability and response speed.
3Measurement precision
If the system monitors driver eye position and vehicle disturbances continuously, then the accuracy of visual output positioning improves, but the energy consumption and computational load increase
Solution Approach 1:
The system achieves multi-functionality by using the camera system and sensors for multiple purposes: detecting driver eye position, identifying external objects in the environment, and monitoring vehicle disturbance events. This universal approach allows accurate visual output positioning while optimizing energy consumption by reusing existing hardware components for multiple detection functions rather than requiring separate dedicated systems.

AI summary
A method for providing information related to an external object in a field of view of a driver of a vehicle comprises that the driver is monitored by a camera system, and that an estimated eye position is identified based on data provided by the camera system. Spatial information is gathered for at least one external object outside the vehicle. A basic display location is determined for a visual output related to the external object based on the spatial information. At least one imminent or instantaneous disturbance event for the vehicle is detected. An eye position correction and/or a display location correction are determined in response to the imminent or instantaneous disturbance event. The visual output related to the external object is generated based on the estimated eye position and the basic display location and based on the eye position correction and/or the display location correction.
