Virtual Dashboard Rear-View Display for Turn Signal Awareness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional digital dashboards in vehicles, such as motorcycles, cannot display rear-view images due to size limitations, hindering drivers' awareness of road conditions behind them when turning or changing lanes.
Innovation Solution
A mobile device with a display, transceiver, and processor is used to receive and display rear-view images on a virtual dashboard, triggered by direction indicator lights, allowing the rear-view image to be shown on a dedicated area, enhancing visibility and safety during turns or lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a traditional digital dashboard is used in a vehicle, then the dashboard can display digital information such as speed and time, but it cannot display rear-view images due to size limitations
Solution Approach 1:
The patent combines the traditional digital dashboard with a mobile device (smartphone or tablet) to create an integrated display system. The mobile device's larger screen is used to display rear-view images from cameras, while the traditional dashboard continues to display basic digital information. This merging allows the system to overcome the size limitation of the dashboard while maintaining its existing functionality.
Solution Approach 2:
The mobile device serves multiple functions: it displays rear-view images from multiple cameras, shows navigation information, and can function as an additional dashboard display. By making the mobile device universal and multi-functional, the system accommodates the rear-view image display requirement without adding dedicated single-purpose equipment.
2Loss of information
If the rear-view image is displayed on the virtual dashboard, then the driver can see road conditions behind during turns or lane changes, but the display area for other dashboard information is reduced
Solution Approach 1:
The display system is segmented into multiple independent display areas on the mobile device screen. Different cameras can be assigned to different regions of the screen, and the system can selectively activate specific camera feeds based on driving conditions. This segmentation allows efficient use of display space while maintaining awareness of rear conditions.
Solution Approach 2:
The display system dynamically adjusts which rear-view images are shown and where they are positioned on the screen based on vehicle state. When the vehicle is going straight, rear-view images may be minimized or shown in smaller areas. When turning or changing lanes, the system activates relevant camera feeds and allocates appropriate display areas, optimizing both safety and information display.
3Ease of manufacture
If a mobile device is used to replace the traditional digital dashboard, then production costs and maintenance are reduced, but the device must accommodate multiple functions including rear-view image display
Solution Approach 1:
The patent leverages the inherent multi-functionality of mobile devices, which are already equipped with processors, displays, cameras, and communication capabilities. By utilizing these existing capabilities for rear-view image display and dashboard functions, the system avoids the need for dedicated equipment, thereby reducing production costs and maintenance requirements while maintaining versatility.
Solution Approach 2:
The mobile device uses its own built-in resources (processor, display, operating system) to handle rear-view image processing and display without requiring additional dedicated hardware resources. The device's existing camera modules can also serve dual purposes for both general photography and rear-view monitoring, reducing the need for separate equipment.

AI summary
A method of displaying a rear-view image and a mobile device using the method are provided. The method includes: receiving the rear-view image; displaying a virtual dashboard through a display; and displaying the rear-view image on a default area of the virtual dashboard in response to receiving a signal associated with a direction indicator light, wherein the default area corresponds to the direction indicator light.
