Cloud-Based Electronic Key Permission Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle key systems lack the ability for owners to remotely control and monitor permissions, allowing unlimited access and usage by authorized users, and do not support user-specific permissions or real-time tracking, especially in a cloud network environment.
Innovation Solution
A system and method for generating and managing electronic keys with multiple permission settings over a cloud network, allowing owners to remotely grant and modify access permissions for registered users, including real-time updates and storage of these settings, using processors connected to the cloud network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical key is transferred to an authorized user, then the user can access and operate the vehicle, but the owner cannot remotely control or monitor permissions and the user has unlimited access
Solution Approach 1:
The patent replaces the mechanical physical key system with an electronic key system that uses digital credentials stored on a user device. This substitution enables remote permission control through electronic communication channels and allows the owner to monitor and modify permissions without physical key transfer, directly resolving the contradiction between ease of remote operation and loss of permission information.
Solution Approach 2:
The patent introduces a cloud-based server as an intermediary between the vehicle owner and the authorized user. The server manages electronic key distribution, stores permission settings, and enables remote communication for permission modification. This intermediary facilitates remote control capabilities while maintaining the owner's ability to monitor and control access permissions.
2Adaptability or versatility
If a physical key is used, then the user can operate the vehicle, but the key cannot be modified or restricted remotely
Solution Approach 1:
The patent replaces the static mechanical key with a dynamic electronic key system that allows remote modification of permissions through digital communication. The electronic key stored on the user device can be updated via wireless communication, enabling the owner to adjust permissions instantly without meeting the user physically, thus providing permission flexibility while eliminating time loss.
Solution Approach 2:
The patent implements preliminary action by pre-configuring multiple permission profiles with different access levels and restrictions. The owner can set up various permission templates in advance (e.g., different speed limits, time restrictions, geographic boundaries) and assign them to users as needed, allowing rapid adaptation to different situations without time-consuming customization during actual use.
3Ease of operation
If smart keys or keyless authorization are used, then access is enabled, but the system cannot prevent unwanted access to vehicle functions
Solution Approach 1:
The patent applies local quality by implementing fine-grained permission control that restricts access to specific vehicle functions rather than providing universal access. Different electronic key profiles can grant access to different vehicle subsystems (e.g., engine, radio, climate control, trunk) independently. This allows the owner to enable convenient access to necessary functions while preventing unwanted access to other functions, directly addressing the security vulnerability of traditional keyless systems.
Solution Approach 2:
The patent utilizes parameter changes by dynamically modifying electronic key parameters such as permission levels, time restrictions, geographic boundaries, and functional access rights. The system can adjust these parameters remotely based on user behavior, location, time of day, or other conditions, enabling convenient access under normal circumstances while automatically preventing unwanted access when parameter conditions are not met.

AI summary
A system for remotely granting vehicle permissions over a cloud network may be performed by one or more processors connected to the cloud network. The one or more processors may generate an electronic key for permitting one or more registered users to access and operate a vehicle, and the electronic key may include a plurality of permission settings. The one or more processors may provide the electronic key to the one or more registered users through the cloud network, receive at least one update from the vehicle or the one or more registered users through the cloud network, modify at least one permission setting associated with the electronic key based on the received update, and provide the modified permission setting to the one or more registered users through the cloud network. The system may further include a storage device configured to store the electronic key and the permission settings.
