Vehicle Remote Control Access by Key-Based Terminal Registration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle parking assistance systems face challenges in managing terminal registrations for multiple users, particularly in shared vehicle scenarios, which affects convenience and safety.
Innovation Solution
A control device for vehicles that includes a processor capable of starting the vehicle based on different types of keys, with a storage unit managing terminal information for remote control, allowing for autonomous movement and limiting access based on key types, enabling secure and convenient user registration and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminal information is stored in the storage unit for remote control, then convenience for multiple users is improved, but security and access control deteriorate
Solution Approach 1:
The patent applies local quality by associating different access rights with different key types. Owner keys grant full access including terminal registration, while user keys grant only remote control access. This differentiated access control resolves the contradiction by providing convenience for multiple users while maintaining security through role-based permissions.
Solution Approach 2:
The patent segments the access control system into different key types (owner key and user key) with distinct functionalities. This segmentation allows the system to simultaneously support multiple users for remote control while preventing unauthorized terminal registration, thus resolving the security-convenience contradiction.
2Ease of operation
If terminal registration is allowed for all key types, then ease of use for shared vehicles is improved, but unauthorized access control deteriorates
Solution Approach 1:
The patent implements local quality by assigning different registration capabilities to different key types. Owner keys enable terminal registration while user keys do not. This resolves the contradiction by allowing ease of use for shared vehicles through user key remote control while preventing unauthorized access through restricted registration rights.
Solution Approach 2:
The processor acts as an intermediary that mediates between different key types and the terminal registration function. It verifies key types and selectively permits or denies registration based on the key type, thus enabling ease of use while preventing unauthorized access.
3Adaptability or versatility
If multiple terminals are registered for remote control, then versatility for shared usage is improved, but system complexity deteriorates
Solution Approach 1:
The patent applies local quality by differentiating access rights based on key types. Owner keys can register multiple terminals while user keys cannot. This resolves the contradiction by providing versatility for shared usage through multiple registered terminals while simplifying the system by preventing unnecessary registration attempts from user keys.

AI summary
A control device for a vehicle includes: a processor configured to start the vehicle in response to operation of one of a plurality of types of keys. The processor is accessible to a storage unit in which terminal information of a terminal for remotely controlling the vehicle is stored in association with the vehicle, the processor is configured to control autonomous movement of the vehicle in response to an operation of the terminal whose terminal information is stored in the storage unit, and the processor is configured to perform limitation of the terminal information in the storage unit based on the type of the key used to start the vehicle.
