Tire Path HUD Display for Narrow-Road Vehicle Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drive support technologies, such as displaying vehicle width on a head-up display, do not adequately assist drivers in navigating narrow roads or avoiding obstacles, particularly for novice drivers, as they fail to provide clear guidance on tire positions and passage paths.
Innovation Solution
An information processing device that displays expected passage paths of vehicle tires on a display unit, adjusting the display based on steering angle, tire widths, and obstacle detection, and compensates for variations in the driver's head position or viewpoint, using a head-up display, display monitor, or head-mounted display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If vehicle width is displayed on head-up display, then driver can grasp vehicle width, but driver cannot accurately understand tire positions and passage paths for navigating narrow roads and avoiding obstacles
Solution Approach 1:
The patent segments the vehicle information display into multiple components: vehicle width indication, tire position markers, and expected passage path visualization. This segmentation allows drivers to separately understand vehicle boundaries and tire trajectories, enabling better navigation through narrow roads and obstacle avoidance.
Solution Approach 2:
The patent adds a temporal dimension to the display by showing expected passage paths that predict future tire positions based on current steering input. This transforms static vehicle width information into dynamic trajectory visualization, helping drivers anticipate tire movement and make smoother steering decisions.
2Measurement precision
If expected passage paths of tires are displayed, then driver can accurately grasp tire positions, but display may deviate due to variations in driver's head position or viewpoint
Solution Approach 1:
The patent incorporates driver head position detection as feedback to dynamically adjust the display. By monitoring where the driver is looking and adjusting the projection accordingly, the system maintains accurate tire position indication regardless of head movement, ensuring consistent reliability across different viewing conditions.
Solution Approach 2:
The display system is made dynamic by continuously adjusting the projection parameters based on real-time detection of driver head position and viewpoint. This dynamic adaptation ensures that the expected passage paths remain accurately aligned with the driver's perspective, maintaining measurement precision even as the driver moves their head.
3Loss of information
If visual information is always displayed, then driver has continuous guidance, but driver may feel overwhelmed or distracted
Solution Approach 1:
The patent implements periodic or conditional display activation rather than continuous visualization. The system can activate tire passage path display based on detected driving conditions such as narrow road detection, obstacle presence, or driver request, providing guidance only when needed and reducing potential distraction during normal driving.
Solution Approach 2:
The display system applies different visualization qualities to different driving situations. In critical situations like narrow passage navigation or obstacle avoidance, detailed tire passage information is displayed. In normal driving conditions, the display is minimized or simplified, providing local quality adjustment based on situational needs.
