Vehicle Authentication Zoning for Faster Multi-Device Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing vehicle authentication systems face inefficiencies in determining the absence of multiple mobile devices within a vehicle cabin, leading to prolonged locking times and reduced user convenience, especially when multiple devices are involved, as they require individual confirmation processes that increase with the number of devices.
Innovation Solution
The system employs a first area determination device for simultaneous response requests and a second area determination device for time-difference response requests to quickly ascertain the presence or absence of mobile devices, allowing for constant waiting times regardless of the number of devices, thereby reducing the absence determination time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual confirmation processes are used for each mobile device, then measurement precision of device presence is improved, but loss of time increases due to prolonged absence determination time
Solution Approach 1:
The system divides the vehicle cabin into multiple areas (first area and second area) and uses separate area determination devices for each area. This segmentation allows parallel determination of device presence in different zones, reducing the total time required compared to sequential individual device confirmation.
Solution Approach 2:
The system performs preliminary area determination by checking if any mobile devices are present in the vehicle cabin before executing the door locking operation. This preliminary check using multiple area determination devices running in parallel speeds up the overall process while maintaining accurate detection.
2Adaptability or versatility
If multiple mobile devices are involved, then adaptability of the system is improved, but loss of time increases due to increased confirmation processes
Solution Approach 1:
The system merges the confirmation processes for multiple mobile devices into a unified area determination approach. Instead of confirming each device individually, it determines whether any device is present in the vehicle cabin areas, combining multiple checks into a single efficient operation that scales with the number of devices.
Solution Approach 2:
The system performs a preliminary check to determine if any mobile devices are present in the vehicle cabin areas before proceeding with door locking. This preliminary action using multiple area determination devices running in parallel reduces the time required regardless of how many devices are involved.
3Measurement precision
If sequential individual device confirmation is used, then measurement precision is improved, but productivity decreases due to prolonged locking operations
Solution Approach 1:
The system segments the vehicle cabin into multiple areas with separate determination devices, enabling parallel processing of presence detection. This segmentation maintains measurement precision through dedicated area checks while improving productivity by eliminating sequential delays.
Solution Approach 2:
The system performs preliminary area determination using multiple determination devices in parallel before executing the door locking operation. This preliminary action maintains accurate device presence confirmation while significantly reducing the time required for the locking operation.

AI summary
A vehicle authentication apparatus includes first and second communication devices, first and second area determination devices, and a control execution device. The first communication device specifies a first area as a communication area. The second communication device specifies a second area as the communication area. The first area determination device determines whether the mobile devices are present at the first area based on a communication status of the first communication device with the mobile devices. The second area determination device determines whether at least one of mobile devices is present at the second area based on a communication status of the second communication device with the mobile devices. The control execution device executes predetermined vehicle control in response to determining no mobile devices being present at the first area; and determining at least one of the mobile devices being present at the second area.
