Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle access control systems rely on physical key fobs, which are inconvenient and costly to distribute for remote access, especially for large numbers of vehicles, and current smartphone-to-vehicle systems are not economically viable due to high hardware costs.
Innovation Solution
A remote access system that uses a backend cloud-based provider site to learn and pair with a vehicle's access control system, employing a client device with a learning device and RF signal transmitter to register additional remote entry keys, allowing access via a smartphone app without physical key distribution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If physical key fobs are distributed for remote access, then access control functionality is provided, but cost and inconvenience increase for large numbers of vehicles
Solution Approach 1:
The patent creates virtual copies of key credentials through a learning device that captures authentication data from the vehicle's access control system. Instead of distributing physical key fobs, the system generates digital key credentials stored in a database, which can be accessed by multiple users simultaneously through their smartphones or other devices, eliminating the need for multiple physical keys.
Solution Approach 2:
The patent replaces the mechanical physical key fob system with an electronic/digital credential system. The learning device captures the vehicle's authentication code and communication protocol, then uses this data to generate electronic key credentials that communicate with the vehicle's access control system via electromagnetic signals, substituting mechanical key distribution with digital credential management.
2Ease of operation
If smartphone-to-vehicle systems are implemented, then remote access is enabled, but hardware costs become prohibitive
Solution Approach 1:
The patent introduces a learning device as an intermediary that captures the vehicle's authentication credentials and stores them in a centralized database. This intermediary layer allows standard smartphones to access vehicles without requiring expensive proprietary hardware modifications in the vehicle, as the credential verification is handled through the database and communication protocol rather than specialized hardware.
Solution Approach 2:
The patent creates a universal access system where a single learning device can capture credentials from multiple vehicles of the same Make and Model, and the captured credentials can be used by multiple different users on different smartphones. This multi-functionality eliminates the need for vehicle-specific or user-specific hardware, reducing overall system cost while maintaining broad access capability.
3Adaptability or versatility
If a learning device captures vehicle authentication data, then remote key creation is enabled, but system complexity increases
Solution Approach 1:
The learning device automatically captures the vehicle's authentication code and communication protocol through standardized learning procedures specific to each vehicle Make and Model. The system self-configures by extracting the necessary credentials during a one-time learning process, then automatically stores them in the database without requiring manual configuration or complex system integration, reducing operational complexity despite the enhanced functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and cost-effective remote access to vehicles, supporting scenarios like package delivery and car sharing, by dynamically configuring RF signals and key credentials, thus addressing a large number of vehicles with minimal hardware changes.
Implementation Method 1
The learning device is coupled to a Radio Frequency signal transmitter. The RF signal transmitter is used for transmitting RF signals to a Radio Frequency receiver associated with the access control system of a vehicle.
Data Source
AI summary
A method to learn and then pair with a pre-installed access control system of a vehicle is discussed. Communication is exchanged between the access control system and a backend cloud-based system. Required data of the access control system including its particular authentication code is extracted by a learning device. A vehicle matching data is sent to the backend cloud-based system and the vehicle is registered with the backend cloud-based system. The learning device is registered to the access control system in accordance with learning procedures implemented in the vehicle as remote entry key. The learning device is coupled to a Radio Frequency signal transmitter that has Application-Specific Integrated Circuits to generate stable RF signals at multiple frequency wavelengths. Registration of learning device includes, receiving a first access control telegram message, transmitting the first access control telegram message to the access control system, pairing the learning device with the access control system.
