Vehicle Touchscreen Mirroring for Rear-Seat Remote Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicles often integrate primary touchscreens in the center dashboard, limiting access to rear seat passengers who cannot reach or interact with the touchscreen controls for infotainment systems, HVAC, navigation, and other functions.
Innovation Solution
An auxiliary device with a display and processor is used to mirror the vehicle's touchscreen interface, allowing remote control of vehicle functions via touch controls displayed on the auxiliary device, which can be wirelessly connected to the vehicle's onboard computing system, enabling passengers to access and control vehicle functions from a secondary location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the touchscreen is integrated in the center dashboard, then the vehicle's control functions are consolidated and organized, but rear seat passengers cannot access or interact with the touchscreen controls
Solution Approach 1:
The patent creates a mirrored representation of the vehicle's touchscreen interface on an auxiliary device (such as a smartphone or tablet). This copy allows rear seat passengers to access and control vehicle functions without physically reaching the center dashboard touchscreen, thereby resolving the accessibility issue while maintaining system organization.
Solution Approach 2:
The auxiliary device acts as an intermediary between the vehicle's onboard computing system and the passenger. It receives control commands from the passenger and transmits them to the vehicle system, enabling remote interaction with vehicle functions without requiring direct contact with the primary touchscreen.
2Adaptability or versatility
If multiple devices can access vehicle controls simultaneously, then passenger convenience is improved, but control conflicts and security issues may arise
Solution Approach 1:
The system dynamically manages connections from multiple auxiliary devices by establishing secure sessions with the onboard computing system. It can handle multiple simultaneous connections while maintaining control integrity through session management, allowing different passengers to access vehicle controls without causing conflicts.
Solution Approach 2:
The onboard computing system provides feedback mechanisms to monitor and manage multiple auxiliary device connections. It tracks active sessions, validates control commands, and prevents conflicting operations by coordinating between multiple devices, ensuring reliable and secure control despite multiple access points.

AI summary
Techniques are described that facilitate remotely interfacing with a vehicle touchscreen. According to an embodiment, a method is provided comprising determining touch controls included in a GUI configured for displaying on a touchscreen of the vehicle, wherein the touch controls provide for controlling functions of the vehicle based on first interaction with the touch controls as displayed on the touchscreen. The method further comprises generating a representation of the GUI for display via an auxiliary display of the auxiliary device, the representation comprising one or more graphical controls corresponding to one or more touch controls of the touch controls, and enabling remote control of one or more functions of the functions of the vehicle by the auxiliary device based on second interaction with the one or more graphical controls as displayed via the auxiliary display.
