Vehicle Display Control for Passenger-Driven Road Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle display systems lack usability for manual passenger control of light patterns, are prone to disruption during abnormalities in road surface drawing devices and Head-Up Displays (HUDs), and have limited operating speeds, affecting visual communication between vehicles and passengers.
Innovation Solution
A vehicle display system comprising a first display device for emitting light patterns on the road surface, a second display device for displaying information inside the vehicle, and a display control unit that allows passengers to intuitively control light patterns, continues visual communication during device abnormalities, and optimizes operating speeds of road surface drawing devices and HUDs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the display control unit automatically controls the light pattern emission, then the visual communication function is maintained, but the passenger's manual control capability is limited
Solution Approach 1:
The control system dynamically switches between automatic control mode (by display control unit) and manual control mode (by passenger input). The system adapts its control characteristics based on operational context, allowing the passenger to override automatic control when needed while maintaining automatic control as the default state for normal operation.
2Reliability
If the system relies on both road surface drawing device and HUD for visual communication, then comprehensive information display is achieved, but system reliability decreases when abnormalities occur
Solution Approach 1:
The system prepares backup display paths in advance by establishing alternative communication routes between the display control unit and each display device. When an abnormality is detected in one device, the system has pre-established alternative methods to maintain visual communication, cushioning against the impact of device failure.
Solution Approach 2:
The display control unit serves as an intermediary that can route information to either the road surface drawing device or the HUD based on their operational status. This mediator component enables flexible information distribution and maintains communication continuity by adapting the transmission path according to system state.
3Productivity
If the road surface drawing device and HUD operate at higher speeds, then visual communication efficiency is improved, but system stability may be compromised
Solution Approach 1:
The system employs periodic operation cycles for the road surface drawing device and HUD, where information is displayed in discrete time intervals rather than continuous streams. This periodic action allows the system to maintain high operating speeds while providing stabilization periods between updates, reducing the risk of instability from excessive processing speeds.

AI summary
A vehicle display system provided to a vehicle, includes a first display device, a second display device, and a display control unit. The first display device is configured to emit a light pattern toward a road surface outside the vehicle. The second display device is located inside the vehicle and configured to display predetermined information toward a passenger in the vehicle so that the predetermined information is superimposed on a real space outside the vehicle. The display control unit is configured to control the first display device. The display control unit is configured to control emission of the light pattern according to a passenger's input operation on a display area where the predetermined information can be displayed.
