Vehicle Cockpit Screen Mirroring for Remote Multi-Screen Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operation of multiple vehicle screens in an intelligent vehicle cockpit is inconvenient due to the need for users to physically move to interact with screens located away from their seating position, increasing hardware costs and complexity.
Innovation Solution
A method and device that utilizes a head unit to identify operation attributes on a first screen, determine a second screen based on these attributes, and display a mirror interface of the second screen on the first screen, allowing operations to be performed without physical movement by using a simulation touchpad on a mobile terminal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple screens are disposed in different locations in the vehicle cockpit, then the functionality and information display capability are improved, but the ease of operation deteriorates because users need to physically move to operate screens away from their seating position
Solution Approach 1:
The patent displays a mirror interface of the second screen on the first screen, creating a visual copy that allows users to operate remote screens without physically moving. The mirror interface replicates the content and controls of the distant screen, enabling operation from the original seating position.
Solution Approach 2:
The first screen acts as an intermediary device that mediates between the user and the second screen. By displaying the mirror interface on the first screen, it bridges the spatial gap and allows indirect operation of the second screen without requiring the user to relocate.
2Adaptability or versatility
If multiple screens are disposed in different locations in the vehicle cockpit, then the information display capability is improved, but the device complexity increases due to the need for additional physical controls and hardware
Solution Approach 1:
The first screen serves multiple functions: it displays its own content and simultaneously displays the mirror interface of the second screen. This multi-functionality eliminates the need for separate physical controls for each screen, reducing hardware complexity while maintaining the ability to operate multiple screens.
Solution Approach 2:
The patent merges the control interface of the second screen with the display of the first screen. By combining the mirror interface display with the existing first screen, it avoids adding separate control hardware and integrates multiple functions into a single device.
3Productivity
If users need to physically move to operate screens located away from seating position, then the ease of operation deteriorates, but the productivity remains unaffected
Solution Approach 1:
The system prepares the mirror interface in advance on the first screen, so when the user needs to operate the second screen, the interface is already ready and accessible. This preliminary preparation eliminates the need for physical movement and allows immediate operation, maintaining productivity while improving convenience.

AI summary
Embodiments of this application disclose a vehicle cockpit screen operation method and a related device. The method includes: A head unit device obtains attribute information of an operation on a first screen in a plurality of screens in a cockpit; the head unit device determines a second screen from the plurality of screens based on the attribute information; and the head unit device displays a mirror interface of the second screen on the first screen. In embodiments of this application, when different screens in the cockpit need to be operated, only mirrors of the different screens need to be switched, and a user does not need to change a location of the user, thereby improving convenience of an operation on a screen in a vehicle cockpit. In addition, there is no need to add physical hardware to implement operations on the different screens in the cockpit. This can reduce hardware costs.
