Vehicle Door Authentication via Actuation Sequence Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for locking and unlocking motor vehicles are inconvenient and lack user-friendly authentication options, particularly when users want to keep their car keys or mobile devices inside the vehicle.
Innovation Solution
A method utilizing an operating device mounted on the vehicle that communicates with a control device, allowing user authentication through a sequence of actuations on the device, generating an immaterial password for locking and unlocking, and enabling secure access without physical keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If classic user authentication methods (car key, keyless go) are used, then reliable vehicle security is maintained, but user convenience deteriorates when users want to keep keys inside the vehicle
Solution Approach 1:
The patent introduces an intermediary authentication system consisting of an operating device mounted on the vehicle and a communication system. This intermediary layer allows users to authenticate without physical keys by using a sequence of actuations on the operating device, which generates an access key that is verified against stored authorization keys. This resolves the contradiction by providing a keyless authentication method that maintains security while enabling users to leave keys inside the vehicle.
Solution Approach 2:
The patent replaces the mechanical key insertion system with an electronic authentication system. Instead of mechanically inserting a physical key into the ignition or door lock, the system uses electronic signals generated by actuating the operating device in a specific sequence. The control device receives these actuation signals, generates an access key, and compares it with stored authorization keys to determine whether to grant access. This substitution eliminates the need for physical keys while maintaining security through electronic verification.
2Adaptability or versatility
If physical keys are required for authentication, then simple and reliable access control is achieved, but flexibility deteriorates when users need to leave keys inside the vehicle
Solution Approach 1:
The operating device serves multiple functions: it acts as both a normal vehicle control interface and an authentication device. The same operating device that users interact with for normal vehicle operations is also used to generate authentication sequences. This multi-functionality increases adaptability by allowing the system to work in both traditional key-based modes and new keyless modes, while the complexity is managed by reusing existing hardware components rather than adding separate authentication devices.
3Ease of operation
If traditional key-based authentication is used, then straightforward access control is maintained, but user comfort deteriorates in scenarios like beach situations where keys must be carried
Solution Approach 1:
The patent extracts the authentication function from the physical key itself and relocates it to the vehicle-mounted operating device and control system. The physical key is completely removed from the authentication process, and its function is replaced by electronic authentication sequences generated by actuating the operating device. This extraction eliminates the need for users to carry physical keys, thereby improving comfort in scenarios where users want to leave keys inside the vehicle, while the authentication capability is preserved through the extracted and relocated function.

AI summary
A method for locking and unlocking a motor vehicle having an operating device, which is mounted on the motor vehicle and can be actuated, and a communication system is provided. The operating device and the communication system communicate with a control device of the motor vehicle. An authorization key is provided to the control device, which locks the motor vehicle. The motor vehicle is unlocked by the control device if a successful user-authentication of a user of the motor vehicle has been performed. It is essential that the user of the motor vehicle activates and deactivates the execution of the method for locking and unlocking the motor vehicle by the communication system.
