Vehicle Pairing via NFC Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a vehicle fleet setting, it is challenging to simplify and secure the pairing and connection of a mobile handheld device to the correct vehicle without manually inputting vehicle identification data, as existing methods can be time-consuming and prone to errors.
Innovation Solution
The system automatically identifies a vehicle using radio communication, such as near field communication (NFC), or optical tracking, allowing a mobile device to connect to a vehicle by reading identifying information from a vehicle activation device, ensuring secure and simple pairing by comparing received information with a stored set of vehicle identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual input of vehicle identification data is used for pairing, then connection security can be maintained, but the pairing process becomes time-consuming and complicated
Solution Approach 1:
The system performs preliminary actions by storing vehicle identification data in the vehicle's memory before the pairing process. When pairing is initiated, the mobile device automatically retrieves and compares this pre-stored data with the data from the vehicle key, eliminating the need for manual input during the pairing moment.
Solution Approach 2:
The system enables self-service by allowing the mobile device to automatically obtain vehicle identification data directly from the vehicle key through wireless communication. The device autonomously compares this data with stored information and completes the pairing process without requiring user intervention for data entry.
2Measurement precision
If manual input of vehicle identification data is required, then connection accuracy can be ensured, but the process becomes complicated especially with large vehicle fleets
Solution Approach 1:
The system replaces the mechanical/manual process of typing vehicle identification data with wireless electronic data transmission. The mobile device automatically receives vehicle identification data from the vehicle key through wireless communication and performs automated comparison with stored data, eliminating manual input operations.
Solution Approach 2:
The system uses copying by retrieving a copy of the vehicle identification data that is already stored in the vehicle's memory. This pre-stored copy is automatically compared with the data transmitted from the vehicle key, ensuring accurate identification without requiring users to manually enter or recall the identification data.
3Ease of operation
If automatic identification through wireless communication is implemented, then pairing simplicity is improved, but connection security requirements become more challenging
Solution Approach 1:
The system implements feedback by automatically comparing the vehicle identification data received from the vehicle key with the pre-stored data in the mobile device. This comparison provides verification feedback to confirm whether the identified vehicle matches the authorized vehicle, ensuring secure connection before enabling vehicle functions.
