HUD Integrated Cluster for Vehicle Rear View Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers face inconvenience and risk of distraction due to frequent gaze shifts between the front and rear environments while driving, as existing head-up display (HUD) systems only display front views and require manual checks of side and rear mirrors for complete situational awareness.
Innovation Solution
An HUD integrated cluster system that displays rear view images and warning lights on a dashboard-mounted cluster and HUD, using rear cameras, sensing units, and a microcomputer to control image display based on vehicle speed, gear shift, turn signals, and steering direction, allowing for reduced gaze shifting and enhanced situational awareness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the driver checks side mirrors and rearview mirrors to observe the rear environment, then the driver can obtain comprehensive situational awareness, but the driver's gaze shift distance and time increase
Solution Approach 1:
The patent combines the rear view camera system with the existing HUD and cluster display systems, merging multiple information sources (rear camera, side cameras, HUD, cluster) into a unified display architecture. This integration allows the driver to view rear environment information on the cluster display without shifting gaze to mirrors, reducing gaze shift time while maintaining comprehensive situational awareness.
Solution Approach 2:
The patent introduces a camera system as an intermediary device that captures rear environment images and transmits them to the cluster display. This intermediary approach replaces the need for direct visual inspection of mirrors, allowing the driver to obtain rear view information while maintaining focus on the front road, thereby reducing gaze shift distance and time.
2Loss of information
If the driver checks side mirrors and rearview mirrors to observe the rear environment, then the driver can obtain comprehensive situational awareness, but the driver's attention is diverted from the front view
Solution Approach 1:
The patent merges rear view information display with the front-facing cluster display system, creating a unified information presentation that allows the driver to monitor rear conditions without turning attention away from the front view. This integration eliminates the need to shift attention between separate mirror and dashboard displays, reducing distraction while maintaining situational awareness.
Solution Approach 2:
The patent replaces the mechanical mirror system with an electronic camera-based imaging system. The cameras capture rear environment images that are displayed on the cluster, substituting the mechanical act of turning mirrors with electronic image transmission. This substitution allows the driver to obtain rear view information without the attention-diverting action of physically checking mirrors.
3Device complexity
If the HUD displays only front view information, then the display system remains simple, but the driver must shift gaze to mirrors for rear environment observation
Solution Approach 1:
The patent extends the HUD and cluster display system's functionality to include both front view and rear view information display. The cluster display serves multiple functions: showing traditional vehicle information, navigation, and now rear camera images. This multi-functionality allows the driver to access all necessary information through a single display location, eliminating gaze shifts to mirrors while the added complexity is managed through software integration.
Data Source
AI summary
Disclosed herein is an HUD integrated cluster system for a vehicle camera. The HUD integrated cluster system displays captured images of the rear view of the vehicle on a cluster and an HUD in front of the driver's seat. Thereby, the gaze shift distance and time may be reduced in watching the environment behind the vehicle and a traffic accident resulting from distraction from the front view may be prevented. The HUD integrated cluster system also displays, on the cluster and the HUD in front of the driver's seat, an image of at least one of the views of the rear center, rear left side and rear right side of the vehicle according to the speed of the vehicle, gear shift, blinking of a turn signal, and a steering direction of the steering wheel. Thereby, the driver may easily observe the rear view according to respective situations. In addition, the HUD integrated cluster system displays a captured image of a rear view of the vehicle and a warning light according to an object which is positioned near or is approaching the vehicle. Thereby, the driver's attention may be readily drawn when the vehicle moves backward or changes lanes.
