Adaptive Transceiver Interval for Vehicle Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication systems for shared vehicles consume excessive power due to continuous operation and lack efficiency in determining when a user is approaching, leading to delayed authentication and reduced convenience.
Innovation Solution
An authentication apparatus with a transceiver and controller that operates intermittently, adjusting the interval between working periods based on the scheduled use start time, shortening intervals as the start time approaches to minimize power consumption and ensure timely verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the transceiver operates continuously to ensure immediate user verification, then authentication convenience is improved, but power consumption increases
Solution Approach 1:
The transceiver operates intermittently in periodic cycles rather than continuously. The controller activates the transceiver for specific working time periods at predetermined intervals, and deactivates it during non-working periods. This periodic operation reduces power consumption while still enabling user verification when needed.
Solution Approach 2:
The operating interval of the transceiver is made dynamic and adaptive. The controller adjusts the interval between working time periods based on whether scheduled use start time information has been acquired. When scheduled use information is available, the interval is shortened to ensure timely authentication; when no schedule is known, the interval is extended to save power.
2Loss of energy
If the transceiver operates intermittently with fixed intervals to reduce power consumption, then power efficiency is improved, but authentication response time worsens
Solution Approach 1:
The transceiver's operating interval transitions from a fixed pattern to a dynamic, condition-based schedule. The controller modifies the interval between working time periods based on the acquisition of scheduled use start time information, optimizing the balance between power efficiency and authentication response time according to actual usage scenarios.
Solution Approach 2:
The system uses feedback from scheduled use information to adjust transceiver operation. When the controller acquires scheduled use start time data, it shortens the working intervals to ensure the transceiver is active and ready for authentication before the scheduled time, thus maintaining quick response while managing power consumption.
3Loss of energy
If the transceiver operates intermittently without adjusting intervals to save power, then power consumption is reduced, but authentication timeliness deteriorates
Solution Approach 1:
The transceiver operates with dynamic intervals rather than fixed periodic cycles. The controller adapts the timing of working periods based on scheduled use information, shortening intervals when authentication is expected soon and extending them when no usage is scheduled, thereby optimizing both power consumption and authentication timeliness.
Solution Approach 2:
When scheduled use start time information is acquired, the controller proactively shortens the working time period intervals in advance of the scheduled usage. This preliminary adjustment ensures the transceiver will be active and ready for authentication before the user arrives, improving authentication timeliness without requiring continuous operation.

AI summary
In the case where the scheduled use start time has been acquired, the controller shortens the interval between the adjacent working time periods of the transceiver as the scheduled use start time approaches. Thus, in a case where there is a long time before the scheduled use start time, the power consumption is decreased. As the scheduled use start time approaches, the transceiver verifies the user immediately.
