Windshield Projection for Autonomous Route Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous traveling vehicles do not provide route guidance to operators during autonomous travel, as it may obstruct their view, leading to a lack of awareness about the vehicle's route and potential safety concerns.
Innovation Solution
An information processing system that includes a memory to store target objectives and circuitry to acquire external and internal information, generate an autonomous traveling route, convert it into image information, and output this information to a head-up display on the vehicle's windshield, allowing the operator to view the route while ensuring minimal obstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If route guidance is displayed during autonomous travel, then operator awareness of the vehicle's route is improved, but the operator's view may be obstructed
Solution Approach 1:
The patent projects the route guidance information onto the windshield surface, transitioning from a traditional 2D display plane to a 3D spatial integration where the information appears to float on the windshield. This dimensional transformation allows operators to view route information without the physical obstruction of conventional displays, as the projection is overlaid on the existing transparent surface.
Solution Approach 2:
The windshield serves as an intermediary medium between the route information and the operator's view. By projecting information onto the translucent windshield surface, the system uses the windshield itself as a carrier that allows light transmission while displaying graphical information, thus mediating between the need for information display and the need for unobstructed viewing.
2Object-affected harmful factors
If no route guidance is provided during autonomous travel, then the operator's view remains unobstructed, but the operator lacks awareness of the autonomous traveling route
Solution Approach 1:
The translucent windshield acts as an intermediary that simultaneously provides view transmission and information display capabilities, eliminating the need to choose between view obstruction and information provision.
Solution Approach 2:
By projecting route information onto the windshield's surface, the system adds an information layer in the visual field without occupying physical space that would block the operator's view, effectively utilizing the third dimension (depth/layering) to resolve the contradiction.
3Loss of information
If a conventional display is used to show route information, then route guidance is provided, but the display structure adds complexity to the vehicle system
Solution Approach 1:
The windshield serves multiple functions: it maintains structural integrity of the vehicle, provides a transparent barrier, and simultaneously acts as a display surface for route information. This multi-functionality eliminates the need for separate display devices, reducing overall system complexity.
Solution Approach 2:
The patent extracts the display function from a separate physical display device and integrates it into the existing windshield structure. By removing the need for dedicated display hardware and using the windshield's optical properties, the system reduces component count and structural complexity.

AI summary
An information processing system includes a memory to store information of a target objective set for a mobile apparatus, and circuitry. The circuitry acquires external information of the mobile apparatus, acquires internal information of the mobile apparatus, generates an autonomous traveling route of the mobile apparatus based on the external information, the internal information, and the information of the target objective, converts the autonomous traveling route of the mobile apparatus to image information based on at least one of the external information and the internal information, and outputs the image information indicating the autonomous traveling route of the mobile apparatus.
