Vehicle Anti-Theft Lock Controller ID Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle robbery prevention systems face inconvenience during lock controller replacement, as they require specialized registration devices and complex operations to re-register ID information, such as inserting the key into the key cylinder.
Innovation Solution
A robbery prevention system with a lock controller that includes memory for storing ID information, an auxiliary controller for data transmission and backup, and searching and storing means to facilitate ID registration by transmitting response signals to portable devices within a detection range, allowing for simplified registration without the need for specialized devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a specialized registration device is used to register ID information on a new lock controller, then the ID information can be accurately transferred, but the user must seek a specialist and the process becomes inconvenient
Solution Approach 1:
The system enables the lock controller to automatically obtain ID information from the auxiliary controller without requiring external specialized registration devices or specialist intervention. The lock controller autonomously performs the registration process by receiving ID information directly from the auxiliary controller through data transmission, making the system self-sufficient during lock controller replacement.
Solution Approach 2:
The auxiliary controller serves as an intermediary between the original lock controller and the new lock controller. It stores backup ID information and transmits it to the new lock controller, facilitating the transfer process without requiring specialized external registration devices.
2Ease of operation
If ID information is transmitted from the engine controller to the lock controller during replacement, then no special registration device is needed, but the key must be inserted into the key cylinder which is complicated and troublesome
Solution Approach 1:
The system extracts the ID information registration function from the key cylinder insertion process. Instead of requiring key insertion to trigger registration, the auxiliary controller directly transmits the ID information to the new lock controller through data communication, separating the registration function from the mechanical key insertion operation.
Solution Approach 2:
The mechanical key insertion operation is replaced with an electronic data transmission process. The auxiliary controller electronically transmits ID information to the new lock controller, substituting the mechanical key cylinder insertion with a digital communication process that is simpler and more direct.
3Reliability
If the lock controller stores ID information in memory means, then authentication is secure, but the system requires backup and transmission mechanisms when the lock controller is replaced
Solution Approach 1:
The auxiliary controller performs preliminary action by storing backup ID information in advance before the lock controller is replaced. This pre-stored information is readily available for transmission to the new lock controller, ensuring that authentication security is maintained without requiring complex real-time retrieval processes during replacement.
Solution Approach 2:
The system changes the state of ID information from being stored only in the lock controller to being stored in both the lock controller and the auxiliary controller as backup. This parameter change in information storage distribution enhances both security and adaptability during replacement scenarios.

AI summary
An anti-theft system for a vehicle that registers ID information at the time of replacement of a lock controller. A portable device, such as a key, has exclusive ID information. A lock controller locks or unlocks a control target device according to an authentication result of the portable device. An auxiliary controller transmits and receives data to and from the lock controller and stores the ID information of the portable device as backup data. The lock controller receives the ID information from the auxiliary controller, and transmits a response requiring signal for searching the portable device which has the ID information received from the auxiliary controller and is present within a predetermined detection range. Then, the lock controller stores the ID information of the portable device which has transmitted a response signal to the response requiring signal.
