Vehicle Terminal Authentication and Pairing Screen Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems face difficulties in simplifying the pairing process between portable terminal devices and in-vehicle instruments, making it challenging for them to communicate effectively.
Innovation Solution
A vehicle control device and program that include a terminal device authentication unit, communication unit, and control unit to authenticate and communicate with terminal devices, allowing for simplified pairing by determining the presence of registered devices and outputting screens for setting communication, thereby facilitating communication between portable terminal devices and in-vehicle control devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pairing process is performed between terminal device and in-vehicle instrument, then communication between devices is established, but the operation procedure becomes complex and time-consuming
Solution Approach 1:
The system performs preliminary authentication of the terminal device by the in-vehicle instrument before the pairing operation. The in-vehicle instrument authenticates the terminal device in advance, and only displays the pairing screen after successful authentication. This preliminary action eliminates the need for complex manual pairing operations while ensuring communication reliability through pre-verification of device legitimacy.
2Reliability
If authentication process is added before communication setup, then communication reliability is improved, but the time required for device pairing increases
Solution Approach 1:
The authentication process operates automatically without requiring user intervention. The in-vehicle instrument autonomously authenticates the terminal device using stored credential information, and automatically proceeds to display the pairing screen upon successful authentication. This self-service mechanism eliminates manual authentication steps while maintaining security, thereby reducing overall pairing time without compromising reliability.
3Adaptability or versatility
If multiple terminal devices are supported, then system versatility is improved, but device management complexity increases
Solution Approach 1:
The system stores credential information (terminal information) for multiple terminal devices in the in-vehicle instrument. Each authenticated terminal device is identified and managed through stored credential copies, allowing the system to support multiple devices without requiring complex real-time verification procedures. The pairing screen displays terminal information based on stored data, enabling versatile multi-device support while simplifying management through pre-stored credential copies.

AI summary
A vehicle control device is provided. The vehicle control device includes a terminal device authentication unit that determines whether a terminal device of a user registered as a user of a vehicle, in advance, is present around or within the vehicle. The vehicle control device also includes a communication unit that communicates with the terminal device. Also included in the vehicle control device is a control unit that causes a display device provided in the vehicle to output a screen for setting communication between the communication unit and the terminal device. The display device outputs the screen in a case where it is determined by the terminal device authentication unit that the terminal device is present and the display device is started up.
