Car Control System Keyless Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart key systems for motor vehicles require a separate smart key for operation, lack theft prevention and location tracking capabilities, and do not allow for remote control without an internal car control device.
Innovation Solution
A car control system utilizing a user terminal that connects via short-range wireless communication to a car access device, which authenticates with an authentication server using terminal and vehicle identification information, enabling control of the vehicle without a separate smart key and providing location tracking and theft prevention features.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate smart key is used for vehicle control, then the vehicle can be controlled remotely, but the system requires an additional physical device that users must carry and manage
Solution Approach 1:
The patent merges the vehicle control function with the user's existing terminal device (smartphone, tablet, or computer). Instead of requiring a separate smart key, the terminal device that users already carry is used for authentication and control. This eliminates the need for an additional physical device while maintaining remote control capability.
Solution Approach 2:
The terminal device serves multiple functions: it acts as an authentication credential, a remote control interface, and a communication bridge between the user and the vehicle. This multi-functional approach replaces the dedicated smart key with a versatile device users already possess.
2Reliability
If traditional smart key systems are used, then vehicle access control is provided, but the system lacks theft prevention and location tracking capabilities
Solution Approach 1:
The terminal device-based system provides multiple security functions including authentication, theft prevention, and location tracking through a single integrated system. The server can communicate with both the terminal device and the vehicle to implement comprehensive security measures beyond simple access control.
Solution Approach 2:
The system implements feedback mechanisms where the server receives status information from the vehicle (including location data) and can send control commands back to the vehicle through the terminal device. This enables real-time monitoring and responsive security actions such as remote locking or alarm activation.
Data Source
AI summary
A car control system is disclosed. The car control system for controlling a car by being linked with a car control device (electronic control unit, ECU) that is installed inside the car for electronic control of the car can include: an authentication server configured to perform access authentication for a user terminal and configured to generate an authentication result based on least one of terminal information of the user terminal and vehicle identification information; and a car access device configured to be directly connected with the car control device through an internal network of the car and configured to determine whether a car control request for control of the car by the user terminal is to be relayed to the car control device according to the authentication result of the user terminal.
