Vehicle Terminal Server Sync for Driver Settings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle-side control systems cannot change the setting state of vehicle facilities without retained information, leading to incomplete or incorrect configuration for drivers.
Innovation Solution
A vehicle-mounted terminal device that acquires driver identification information, communicates with a server to receive personal setting information, and adjusts settings for vehicle-mounted apparatuses based on this information, ensuring appropriate configuration upon driver authentication and power supply activation, with options for storage in portable or vehicle-mounted devices and adjustment for vehicle type compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the vehicle-side control system does not retain information indicating setting states of the vehicle facilities, then the device complexity is reduced, but the ability to perform personalized setting changes is lost
Solution Approach 1:
The patent introduces a server as an intermediary component that stores and manages personalized setting information. The vehicle-side control system communicates with this server to retrieve and apply settings, thereby maintaining personalized capability without requiring complex local storage and management systems. The server acts as the mediator between the driver's identification and the vehicle's setting configuration.
Solution Approach 2:
The system retrieves setting information from the server, which contains copies of personalized configurations for different drivers. These setting copies are transmitted to the vehicle control system and applied without requiring the vehicle to permanently store multiple complete setting profiles locally, thus reducing device complexity while maintaining adaptability.
2Reliability
If personal setting information is stored only in the vehicle-mounted terminal device, then data security is improved, but accessibility across different vehicles is reduced
Solution Approach 1:
The patent merges the storage function between two locations: the server and the vehicle-mounted terminal device. The server provides centralized storage for cross-vehicle accessibility, while the local device maintains a cache or copy for security and immediate access. This combination allows the system to achieve both data security through local storage and cross-vehicle accessibility through server connectivity.
Solution Approach 2:
The server provides a universal storage solution that serves multiple vehicles and multiple drivers, enabling the same personalized settings to be accessed across different vehicle instances. The vehicle-mounted terminal device simultaneously serves as both a secure local storage unit and a communication interface to the universal server system.
3Measurement precision
If the system requires server communication for every setting change, then data accuracy is improved, but communication time and energy consumption increase
Solution Approach 1:
The system performs preliminary actions by caching or pre-loading setting information from the server into the vehicle-mounted terminal device. When the vehicle is used, the settings are already available locally, eliminating the need for real-time server communication during normal operation. This preliminary storage action ensures data accuracy is maintained while significantly reducing communication time and energy consumption during actual use.
Solution Approach 2:
The system implements local quality by allowing the vehicle-mounted terminal device to store and process setting information locally rather than requiring constant server communication. The local device has the quality of autonomous setting management, while the server provides the quality of centralized data accuracy. This distribution of functionality reduces communication overhead while maintaining data integrity.

AI summary
In a vehicle-mounted terminal device configured to be mounted on a vehicle and capable of communicating with a server device, a communication unit transmits identification information of a driver of the vehicle to the server device and receives personal setting information, indicating a setting state of a vehicle-mounted apparatus, transmitted from the server device and related to the identification information of the driver. A setting unit makes setting of a vehicle-mounted apparatus on the vehicle based on the personal setting information received at the communication unit. When the authentication of the driver is completed and when a power supply of the vehicle is turned on, the communication unit receives personal setting information for a vehicle-mounted apparatus, transmitted from the server device and related to the identification information of the driver.
