Innovation Solution
A computer-implemented method and system for extracting vehicle operation data from internal automotive networks via iterative interrogation and heuristic selection, using a data harvesting device that connects to OBD-II ports and processes data for wireless transfer to a host system, capable of handling multiple vehicle makes and models, including proprietary protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a device is connected to the OBD-II port to extract vehicle operation data, then data collection capability is improved, but the device may interfere with safe operation of the vehicle or be damaged due to contact with vehicle operators
Solution Approach 1:
The patent relocates the data extraction device from the traditional OBD-II port location (within easy reach of the driver) to the vehicle's power distribution box, which is typically located in the engine compartment. This spatial relocation removes the device from the hazardous zone where it could contact the driver's feet or hands during normal operation, while still maintaining electrical connectivity to access vehicle data through the power distribution box's access to vehicle systems.
2Ease of operation
If the OBD-II port is located in visible areas or behind access doors, then device installation may be compromised due to aesthetics or physical control interference, but moving the port location varies by vehicle model
Solution Approach 1:
The patent develops a universal data extraction device that can interface with the power distribution box across multiple vehicle makes and models. The device incorporates adaptable connection mechanisms and software that can recognize and communicate with different vehicle systems through the power distribution box, eliminating the need for vehicle-specific OBD-II port adaptations while maintaining broad compatibility.
3Ease of manufacture
If prior art technologies use OBD-II ports for data collection, then affordability is improved, but data reliability and accuracy for real-time vehicle health monitoring is insufficient
Solution Approach 1:
The patent uses the power distribution box as an intermediary access point to reach more reliable data sources within the vehicle's electrical system. By routing through the power distribution box, the device can access raw electrical signals and operational data directly from vehicle components, providing more accurate real-time measurements compared to processed data available through standard OBD-II ports.
Data Source
AI summary
Systems, methods, and related computer programs are provided wherein vehicle operation data is extracted from an internal automotive network. In an embodiment, a method comprises: i) obtaining data available on the internal automotive network via iterative interrogation; ii) analyzing the obtained data to identify a set of candidate data values having at least one common feature within a suitable proximity margin; and iii) heuristically selecting a candidate data value best matching one or more selection criteria to identify a true value. These systems and methods allow data to be extracted from proprietary and non-proprietary busses in the internal automotive network.
