Vehicle Sensor Authentication for Installation Position Errors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing object detection devices struggle to accurately detect errors in the installation of transmission and reception devices on vehicles, particularly when these devices are reasssembled or incorrectly installed between vehicles.
Innovation Solution
An object detection device that assigns unique first identification codes to transmission and reception devices at predetermined timings, reads second identification codes from these devices, and authenticates them based on pre-stored data associations, enabling accurate detection of installation errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transmission and reception devices are reasssembled to a vehicle, then device reusability is improved, but installation position accuracy deteriorates
Solution Approach 1:
The system performs preliminary authentication by comparing the unique ID of each transmission and reception device with pre-stored installation position information before the device is actually installed. This preliminary check prevents incorrect installations from occurring in the first place, resolving the contradiction by ensuring position accuracy is maintained even when devices are reasssembled.
Solution Approach 2:
The system provides feedback by notifying the user when a mismatch between device unique ID and installation position is detected. This feedback mechanism allows operators to correct installation errors immediately, maintaining position accuracy while still allowing device reusability through proper reassignment procedures.
2Adaptability or versatility
If transmission and reception devices are reasssembled to a vehicle, then device reusability is improved, but installation error detection capability deteriorates
Solution Approach 1:
The system detects installation errors by comparing the unique ID read from each device with the pre-stored correct installation position information. When a mismatch is detected, the system provides feedback by notifying the user of the installation error. This enables reliable error detection while still allowing device reusability through proper authentication procedures.
3Measurement precision
If identification codes are assigned to transmission and reception devices, then device identification capability is improved, but system complexity deteriorates
Solution Approach 1:
The system uses the unique ID already embedded in each transmission and reception device as a natural identifier, eliminating the need for separate identification code assignment procedures. This copying approach maintains device identification capability while reducing system complexity by leveraging existing device characteristics.
