Vehicle Switch Input for User Terminal Control Without Retrofit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies require a retrofitted dedicated controller for operating a user terminal in a vehicle, which can be inconvenient and unsafe, especially if the controller cannot be easily installed or operated by the driver.
Innovation Solution
An information processing device mounted on a vehicle that detects operations on existing switches by a predetermined method, where the function of the corresponding device is not exerted, and transmits a command to a user terminal to perform a predetermined action.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a retrofitted dedicated controller is installed to operate a user terminal in a vehicle, then the user terminal can be operated, but the device complexity increases and installation becomes inconvenient
Solution Approach 1:
The patent applies universality by enabling existing vehicle switches to perform multiple functions: their original device control functions plus the additional function of operating the user terminal. The control unit detects operations on existing switches and translates them into commands for the user terminal, eliminating the need for a dedicated controller and allowing existing components to serve dual purposes.
2Ease of operation
If a retrofitted dedicated controller is installed to operate a user terminal in a vehicle, then the user terminal can be operated, but the installation process becomes unsafe and inconvenient for the driver
Solution Approach 1:
The system applies self-service by allowing the driver to operate the user terminal through existing vehicle switches that are already familiar and accessible during normal driving. The control unit automatically detects switch operations and executes the corresponding user terminal commands without requiring the driver to learn new controls or perform complex installation procedures, making the system safe and convenient for in-vehicle use.
3Device complexity
If existing switches are used to operate the user terminal, then device complexity is reduced, but it may be difficult to distinguish terminal operation commands from normal device operations
Solution Approach 1:
The patent applies preliminary action by pre-defining specific operation patterns for the existing switches that are dedicated to user terminal control. These predetermined operation methods are established before use, allowing the control unit to clearly distinguish between normal device operations and user terminal commands based on pre-programmed detection criteria, eliminating ambiguity without adding complex real-time analysis.

AI summary
The control unit of the information processing device detects that a specific switch among the plurality of existing switches for operating each of the plurality of devices existing in the vehicle is operated by a predetermined method in which the function of the corresponding device is not exerted. The control unit of the information processing device transmits a command for causing the user terminal used by the user associated with the vehicle to perform a predetermined operation in response to the detection of the operation of the specific switch by the predetermined method.
