Vehicle Control Device Intersection Guidance via AR Projection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle control systems lack an efficient method to guide vehicles through intersections by utilizing objects around the intersection, especially in autonomous driving modes, which can lead to confusion and inefficiency.
Innovation Solution
A vehicle control device equipped with a communication unit, sensing unit, and processor that receives location information, detects objects around the intersection, and provides guidance to the driver using these objects, adjusting the guidance based on the driver's attention and vehicle operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the vehicle control system provides detailed route guidance information to drivers, then the guidance completeness is improved, but the driver's attention is diverted from the road
Solution Approach 1:
The patent introduces an intermediary system (AR display on windshield or window) that mediates between the navigation information and the driver's view of the road. The guide information is projected through the windshield or displayed on the window, allowing drivers to see both the road and guidance information simultaneously without diverting attention to separate displays
Solution Approach 2:
The patent transitions guidance information from a traditional 2D display plane (screens) to a 3D spatial dimension by projecting AR images directly onto the windshield or window surface. This allows guidance information to be displayed in the driver's field of view without requiring the driver to shift focus to a separate display device
2Loss of information
If the vehicle uses traditional navigation displays to provide route guidance, then the guidance information can be transmitted, but the driver cannot intuitively understand the route at intersections
Solution Approach 1:
The patent creates visual copies of the real-world environment (intersection layout, road markings, surrounding objects) through camera capture and processes these images to overlay guidance information. This copying approach allows the guidance system to present familiar visual references that drivers can intuitively understand rather than abstract symbolic representations
Solution Approach 2:
The patent uses color-coded visual indicators (arrows, highlights, and graphical overlays) to differentiate route directions and important navigation elements. Color changes and visual enhancements make the guidance information more distinguishable and easier to understand at a glance
3Adaptability or versatility
If the vehicle control system continuously monitors driver behavior to adjust guidance output, then the guidance adaptability is improved, but the system complexity increases
Solution Approach 1:
The patent implements feedback mechanisms where the system monitors driver responses (acknowledgment of guidance, vehicle operations) and adjusts subsequent guidance output accordingly. The processor determines whether to repeat or modify guidance based on driver behavior, creating an adaptive loop that responds to driver needs without requiring complex predictive models
Solution Approach 2:
The guidance system serves itself by automatically adjusting its output based on driver responses. When the driver acknowledges guidance or performs the indicated maneuver, the system automatically terminates or modifies further guidance output without requiring manual intervention or complex external control

AI summary
A vehicle control device includes a communication unit configured to receive location information of a vehicle, a sensing unit, a display unit, and at least one processor that is configured to determine, based on the location information received by the communication unit, that the vehicle has entered an area within a predetermined distance from an intersection at which the vehicle changes a travel direction according to a preset route information. The at least one processor is further configured to detect an object located around the intersection through the sensing unit, and to control the display unit to output a route to an entrance of the intersection based on information related to the object located around the intersection.
