Vehicle Smart Key Driver Identification and Automatic Setting Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle convenience systems fail to accurately determine the actual driver when multiple people share a vehicle, leading to confusion and potential safety issues, as they require manual resetting and expose personal information.
Innovation Solution
A system using a smart key that periodically transmits identification information to an external device, allowing for automatic detection and display of the actual driver's information, and control of vehicle settings without additional hardware, using criteria such as proximity and preset preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual memory buttons are used for driver settings, then driver preferences can be stored, but it becomes confusing to identify which button belongs to which driver and requires manual resetting
Solution Approach 1:
The system automatically detects which driver is approaching the vehicle using the smart key and externally displayed information, and autonomously recalls the corresponding driver's settings without requiring manual button selection. The driver simply needs to approach the vehicle, and the system handles the rest automatically.
Solution Approach 2:
The patent replaces the mechanical memory button system with an electronic automatic detection system using smart key communication and external display units. This substitution eliminates the need for physical button identification and enables automatic driver recognition and settings recall.
2Measurement precision
If contact information is always displayed inside the vehicle, then external driver identification is possible, but personal information is easily exposed even when unnecessary
Solution Approach 1:
The external display unit dynamically adjusts its operation based on the detected driver's preferences. Some drivers choose to have their contact information displayed externally, while others opt for privacy. The system adapts to each driver's individual settings rather than using a fixed display policy for all drivers.
Solution Approach 2:
The system applies different display policies to different drivers based on their individual preferences. Each driver can set whether their information should be externally displayed, creating localized quality differences in information exposure across different users of the same vehicle.
3Adaptability or versatility
If multiple drivers share a vehicle with manual settings, then vehicle usage is flexible, but it is impossible to precisely determine who the actual driver is
Solution Approach 1:
The system provides visual feedback through the external display unit showing which driver is currently detected and will be using the vehicle. This feedback mechanism allows bystanders to precisely identify the actual driver without ambiguity, while still maintaining flexible multi-driver vehicle sharing capability.

AI summary
A vehicle includes a smart key which periodically transmits identification information to an external device, a communication unit which receives information on a driver corresponding to the identification information generated by the smart key from the external device, and a control unit which displays information preset by the driver based on the information on the driver received from the communication unit or automatically controls devices in the vehicle pre-stored by the driver.
