Vehicle Immobilizer Timer for New Key Learning Theft Delay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Thieves are exploiting advanced tools to add valid new electronic keys to vehicles, enabling quick theft, and existing security measures are being bypassed, necessitating an improved automobile theft prevention technology.
Innovation Solution
Implementing an immobilizer timer that activates when new vehicle keys are registered, immobilizing the vehicle until the timer expires, with duration based on factors like market, vehicle, and key type, and allowing cancellation via proof of ownership or secure access methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical locks and alarm systems are used, then physical obstacles and detection capabilities are provided, but thieves can bypass these measures using advanced hacking tools and keyless entry signal amplifiers
Solution Approach 1:
The system performs preliminary action by detecting key learning attempts and activating the immobilizer timer before the thief can complete the key programming process. The timer prevents the vehicle from being driven away immediately, forcing the thief to wait and potentially be detected.
Solution Approach 2:
The system applies preliminary anti-action by implementing an immobilizer that counteracts the thief's key learning attempt. The immobilizer timer creates a delay that prevents the vehicle operation, directly opposing the thief's goal of quick vehicle access.
2Reliability
If an immobilizer timer is activated upon key learning, then theft prevention is improved by forcing thieves to wait, but the vehicle operation is delayed for legitimate users
Solution Approach 1:
The system applies dynamics by making the immobilizer timer cancellable under certain conditions. The timer duration and activation are dynamic rather than fixed, allowing the system to adapt between preventing theft and enabling legitimate user access based on authentication outcomes.
Solution Approach 2:
The system changes parameters by adjusting the immobilizer timer state based on user authentication. The timer can be cancelled or extended depending on whether the user is legitimate, dynamically changing the time parameter to balance security and convenience.
3Adaptability or versatility
If multi-layered authentication and cancellation options are implemented, then security is enhanced and flexibility for owners is provided, but the system complexity increases
Solution Approach 1:
The system applies universality by implementing multiple cancellation methods that serve different user needs and scenarios. The same immobilizer timer can be cancelled through various authentication mechanisms (owner authentication, dealer authentication, remote server verification), making the system versatile and adaptable to different situations.

AI summary
An electronic device for vehicle immobilizer timer based on electronic key learning to facilitate anti-theft security of a vehicle is provided. The electronic device receives first information indicative of learning of an electronic key of the vehicle. The electronic device controls selection of a delay time of an operation mode of the vehicle, based on the first information. The electronic device controls the operation mode of the vehicle to be set in an immobilized state, based on the delay time and the first information. The circuitry detects whether a request of a user to mobilize the vehicle is received. The circuitry authenticates the user, based on the detection that the request is received. The electronic device controls the operation mode of the vehicle to be set in a mobilized state based on the expiry of the delay time or the authentication of the user.
