Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle access systems require carrying a dedicated component, such as a key fob, and restrict third-party access to vehicle on-board systems, leading to inefficiencies and limited communication capabilities, especially in areas with poor signal reception.
Innovation Solution
An intermediary access device with a secure wireless transceiver for communication with the vehicle's on-board system and a user-initiated communication channel for user electronic devices, eliminating the need for a dedicated access device and enabling secure, efficient command issuance and data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manufacturer-controlled backend-server system is used for third-party access, then vehicle security is maintained, but communication efficiency deteriorates due to signal reception requirements and routing through remote servers
Solution Approach 1:
The patent introduces a backend server as an intermediary component that mediates all communications between user electronic devices and the vehicle's on-board system. The server receives commands from user devices, authenticates them, and relays them to the vehicle, while also receiving vehicle data and forwarding it to users. This intermediary architecture maintains security by centralizing authentication and encryption management while enabling efficient local communication between the vehicle and authorized user devices without requiring direct manufacturer server routing for each interaction.
2Reliability
If RKS key fobs with distinct digital identity codes are used, then vehicle access security is improved, but device complexity increases as users must carry dedicated access components
Solution Approach 1:
The patent enables user electronic devices to serve multiple functions: they act as both the vehicle access key (replacing the RKS key fob) and the communication interface for third-party system access. The same device that unlocks the vehicle can also send commands to and receive data from the vehicle's on-board system through the backend server. This multi-functionality eliminates the need for separate dedicated access devices while maintaining security through the server-mediated authentication process.
Solution Approach 2:
The patent merges the functions of the traditional RKS key fob and the third-party communication interface into a single user electronic device. Instead of requiring users to carry both a key fob for access and a separate device or system for third-party interactions, the invention combines these functionalities so that one device handles both vehicle access and authenticated communication with the on-board system through the backend server.
3Reliability
If encrypted wireless communication channels are established between the intermediary device and vehicle on-board system, then communication security is improved, but energy consumption increases
Solution Approach 1:
The patent implements preliminary authentication and channel establishment through the backend server before actual vehicle commands are transmitted. The security framework, including authentication credentials and encryption parameters, is set up in advance through the server-mediated process. This preliminary action ensures that subsequent communications between the user device and vehicle can proceed with established security measures, reducing the need for repeated heavy authentication handshakes and associated energy consumption during each interaction.

AI summary
An intermediary access device enables a user electronic device to communicate with a vehicle's onboard computer system. A first wireless transceiver of the intermediary access device is used to establish a secure wireless communication channel between the intermediary access device and a vehicle on-board computer system. A second wireless transceiver of the intermediary access device is used to establish a user-initiated communication channel between the intermediary access device and a user electronic device. User commands and vehicle information can then be transmitted between the vehicle on-board computer system and the user electronic device via the intermediary access device in a safe, secure and efficient manner.
