Vehicle Usage Rights Management via Mobile Terminal Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic vehicle keys are not adequately suited for managing usage rights due to limited size, which restricts operating comfort and increases security risks, as they lack sufficient input elements and display capabilities, and their energy requirements are high due to integrated communication modules and small batteries.
Innovation Solution
A communication system comprising a vehicle, a mobile terminal, and an electronic vehicle key with internal and external communication modules, allowing secure allocation and withdrawal of usage rights using the mobile terminal, which enhances security and comfort by utilizing different communication standards and decentralized management systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the electronic vehicle key is made compact, then it is portable and can be carried on a keyring, but it has limited input elements and display capabilities which restricts operating comfort
Solution Approach 1:
The patent introduces a mobile terminal (smartphone or tablet) as an intermediary device that provides the complex input elements and display capabilities needed for managing usage rights. The electronic vehicle key itself remains compact but communicates with the mobile terminal, which serves as an external interface for comfortable operation. This resolves the contradiction by offloading the operational complexity to a separate device that the user already possesses.
2Adaptability or versatility
If communication modules and display devices are integrated into the electronic vehicle key, then usage rights can be managed, but energy requirement increases causing rapid battery discharge
Solution Approach 1:
The patent extracts the energy-intensive communication modules and display devices from the electronic vehicle key and relocates them to the mobile terminal. The key retains only essential functions (identification and basic communication), while the mobile terminal handles the demanding tasks of displaying information and providing input interfaces. This separation dramatically reduces the energy requirements of the key itself.
Solution Approach 2:
The mobile terminal serves multiple functions: it acts as the display device, provides input elements, handles communication protocols, and manages the user interface for usage rights management. By making the mobile terminal a multi-functional device that serves the electronic vehicle key, the system avoids duplicating these functions within the key itself, thereby reducing energy consumption.
3Ease of operation
If touchscreen dimensions are increased for better information display and usage rights management, then operating comfort improves, but the key cannot be conventionally carried on a keyring
Solution Approach 1:
The mobile terminal serves as an intermediary that provides the large touchscreen interface needed for comfortable usage rights management. The electronic vehicle key itself remains small and portable, while the mobile terminal (which the user already carries) provides the extended display and input capabilities. This resolves the contradiction by separating the portability function from the operational interface function.

AI summary
A communication system for managing usage rights to a vehicle, having a vehicle which includes a communication module inside the vehicle, a mobile terminal, and an electronic vehicle key which communicates with the communication module inside the vehicle and with the mobile terminal and allocates usage rights for the vehicle. Allocation of usage rights for the vehicle, which are carried out by the electronic vehicle key, are controlled by the mobile terminal.
