Vehicle Crosswalk Display With Advance Driver Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The sudden appearance of a crosswalk on a road can hinder vehicle driving, as it is not typically displayed and only appears when a pedestrian crosses, causing unexpected visual obstruction for drivers.
Innovation Solution
An information processing system that includes a controller to output advance notification information on a display device, allowing drivers to visually recognize the upcoming crosswalk display by superimposing it on the road surface or road structures, reducing the likelihood of hindrance during driving.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a crosswalk is displayed solely when a pedestrian crosses, then the crosswalk is not normally displayed on the road, but the crosswalk suddenly appears from the viewpoint of a vehicle driver, which may hinder driving of the vehicle
Solution Approach 1:
The system displays advance notification information before the actual crosswalk display to alert drivers in advance. This preliminary action allows drivers to prepare for the upcoming crosswalk, reducing the sudden appearance effect and potential driving hindrance while maintaining crosswalk visibility when needed.
Solution Approach 2:
The patent introduces an intermediary element (advance notification information) between the driver and the crosswalk display. This intermediary provides warning to the driver before the crosswalk appears, mediating the interaction and reducing the harmful effect of sudden visual obstruction while preserving the crosswalk's function.
2Object-affected harmful factors
If advance notification information is displayed, then driving hindrance is reduced, but the system complexity increases
Solution Approach 1:
The display device performs multiple functions: it displays both the actual crosswalk information and the advance notification information. By making the display device universal and multi-functional, the system adds the notification feature without requiring entirely separate hardware, thus managing complexity while improving safety.
Solution Approach 2:
The system changes the temporal parameter of information display by showing notification information at a different time (in advance) and potentially with different visual characteristics. This parameter change approach allows the system to convey additional information using the existing display capabilities, avoiding major system complexity increases.

AI summary
An information processing device includes a controller configured to control display of a crosswalk on a road on which a vehicle travels. The controller outputs information to be displayed on a display device such that a driver of the vehicle visually recognizes advance notification information that makes advance notification of the display of the crosswalk.
