Vehicle Window Display System for Proximity-Based Driver Information
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle display systems fail to provide useful information to drivers when they approach the vehicle and do not adapt displays based on the driver's position relative to the vehicle, leading to potential difficulties in recognizing display content when the driver moves away from the display.
Innovation Solution
A vehicle display system that includes sensors to detect the driver's proximity and position, a HUD device capable of displaying real images on windows, and a controller to switch displays between inside and outside views based on the driver's boarding or exiting the vehicle, ensuring the driver can access necessary information before and during driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the display is provided only inside the vehicle, then the driver can view information during driving, but the driver cannot recognize display content when approaching the vehicle from outside
Solution Approach 1:
The display system dynamically switches between inside-display mode and outside-display mode based on the driver's position relative to the vehicle. When the driver is detected outside the vehicle, the system provides display on the window for outside viewing; when the driver enters, it switches to inside display. This dynamic adaptation resolves the contradiction by making the display system flexible rather than fixed.
Solution Approach 2:
The window display device serves multiple functions: it can display information for drivers outside the vehicle (security mode) and for drivers inside the vehicle (regular mode). This multi-functionality allows a single display system to serve both outside and inside viewing needs, eliminating the contradiction between inside-only and outside-only display capabilities.
2Adaptability or versatility
If the display is switched between inside and outside views, then the driver can access information in both positions, but the system complexity increases
Solution Approach 1:
The system uses sensors to detect the driver's position and provides feedback to the control unit, which then automatically adjusts the display mode accordingly. This feedback mechanism enables automatic adaptation without requiring complex manual control systems, resolving the contradiction by using intelligent automation rather than mechanical complexity.
Solution Approach 2:
The display system automatically detects driver presence and switches between inside and outside display modes without requiring manual intervention. The system serves itself by using sensor data to autonomously determine the appropriate display configuration, reducing the need for complex control interfaces and manual operation.
3Loss of information
If the display is provided on the window for outside viewing, then approaching drivers can see information, but the display may not be visible to drivers inside the vehicle
Solution Approach 1:
The display system dynamically adjusts its viewing orientation based on driver position. When a driver is detected outside the vehicle, the window display presents information visible from outside; when the driver enters, it switches to present information visible from inside. This dynamic reconfiguration ensures information is always accessible to the appropriate viewer without loss.

AI summary
A vehicle display system includes a display device, a determiner, and a display controller. The display device provides a display on a window of a vehicle. The determiner determines whether a driver of the vehicle comes close to the vehicle. The display controller controls the display device to provide the display for an outside of the vehicle, when the determiner determines that the driver of the vehicle comes close to the vehicle.
