Vehicle UWB Diagnostics by User Location for Targeted Components
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for diagnosing vehicle electronic device failures are limited, as they do not provide diagnostic information in real-time or for specific devices when desired by the user, potentially compromising vehicle safety.
Innovation Solution
A vehicle system that enables wireless communication with a user terminal, allowing the vehicle to determine the location of the terminal, identify relevant electronic components, and transmit diagnostic information, including state or failure data, to the terminal for user access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional diagnostic methods (failure lamp checking or OBD connection) are used, then the diagnostic process is simple, but diagnostic information cannot be provided at the desired time point and lacks real-time capability
Solution Approach 1:
The system performs preliminary actions by continuously collecting and storing diagnostic information from vehicle electronic components in real-time before the user needs it. When a user approaches the vehicle with their terminal device, the pre-collected diagnostic data is immediately available for transmission, eliminating the time delay associated with conventional diagnostic methods that require active connection and data retrieval at the moment of need.
2Ease of operation
If diagnostic information is transmitted to user terminal wirelessly, then user convenience is improved, but system complexity increases due to additional communication components
Solution Approach 1:
The controller in the vehicle system performs multiple functions: it manages vehicle electronic components, collects diagnostic information, determines user terminal locations, authenticates users, and transmits diagnostic data wirelessly. By making the controller multi-functional, the patent avoids adding separate dedicated hardware for each function, thereby providing enhanced user convenience while minimizing the increase in system complexity.
3Loss of information
If diagnostic information is provided for all electronic components, then comprehensive information is available, but information overload occurs and relevance to user needs decreases
Solution Approach 1:
The system applies local quality by determining the user terminal's location relative to the vehicle and selectively providing diagnostic information only for electronic components associated with that specific location. For example, if the terminal is detected near the driver's seat area, only diagnostic information relevant to driver-side components is transmitted. This approach maintains information completeness for the relevant subset while eliminating information overload by excluding unrelated components.
4Reliability
If authentication is implemented before transmitting diagnostic information, then security is improved, but the process time increases
Solution Approach 1:
The system performs authentication in advance by continuously monitoring for the presence of authorized terminal devices near the vehicle and pre-validating their authentication credentials. When an authenticated terminal is detected, the system has already completed the authentication process beforehand, so diagnostic information can be transmitted immediately without requiring additional authentication time at the moment of data request, thus maintaining both security and speed.
