Vehicle Telematics Data Upload via ECU Logging Mode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle telematics systems have limitations in data content and reporting intervals, failing to efficiently capture and transmit operational data from vehicles to remote servers, which restricts comprehensive vehicle monitoring and analysis.
Innovation Solution
A system that configures vehicle electronic control units (ECUs) to enter a logging mode based on received VINs, aggregates data, and transmits it using bandwidth configurations tailored to historical throughput requirements, enabling efficient data processing and uploading to a vehicle information server through a telematics control unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If telematics data is transmitted with limited data content and reporting intervals, then network bandwidth consumption is reduced, but vehicle monitoring comprehensiveness and data analysis capability deteriorate
Solution Approach 1:
The system performs preliminary actions by configuring ECUs to enter logging mode and capture operational data locally before transmission is needed. Data is pre-processed and buffered at the vehicle端, allowing comprehensive data collection without immediate network transmission, thus reducing bandwidth consumption while maintaining data completeness.
Solution Approach 2:
The patent extracts only the necessary parameter definitions and configurations from the server and sends them to the vehicle. The actual operational data is captured and processed locally at the ECU level, separating data collection functions from transmission functions. This extraction approach minimizes network traffic while preserving comprehensive vehicle monitoring capability.
2Loss of information
If more operational data is captured and transmitted from vehicles, then vehicle monitoring and analysis capability is improved, but network bandwidth requirements and transmission time increase
Solution Approach 1:
The system pre-configures ECUs with parameter definitions and enters them into logging mode before data transmission is required. Operational data is captured, aggregated, and buffered locally at the ECU level in advance, so that when transmission occurs, the data is already prepared and ready for efficient upload, reducing transmission time while maintaining data completeness.
Solution Approach 2:
The patent segments the data processing function across multiple ECUs, with each ECU independently capturing and buffering its own operational data. This segmentation allows parallel data collection from multiple vehicle systems simultaneously, improving efficiency and reducing the overall time required for comprehensive data gathering before transmission.
3Productivity
If ECUs are configured to capture and aggregate operational data locally, then data transmission efficiency is improved, but ECU configuration complexity increases
Solution Approach 1:
The patent implements a universal parameter definition structure that can be applied across multiple different ECU types and vehicle models. The server generates standardized parameter definitions that configure ECUs to perform multiple functions: capturing operational data, aggregating it locally, buffering it in memory, and preparing it for transmission. This multi-functional approach improves transmission efficiency without proportionally increasing configuration complexity.
Solution Approach 2:
The system dynamically changes ECU operational parameters by sending parameter definitions from the server that adjust logging modes, data capture rates, and buffering configurations based on specific vehicle needs and network conditions. These parameter changes allow the same ECU hardware to adapt to different monitoring requirements without requiring complex custom configurations for each vehicle type.
Data Source
AI summary
A system includes at least one processor configured to, in response to receiving a VIN from a remote vehicle, transmit to the vehicle a parameter definition selected based on fields of the VIN to configure an ECU of the vehicle to enter a logging mode to capture, aggregate, and send operational data of the vehicle, and a bandwidth configuration file for a modem of the vehicle based on historical throughput requirements associated with operational data. The parameter definition may include a reporting application configured to be executed by a processor of the ECU to generate a processed parameter from a raw parameter associated with vehicle operation. Also, the parameter definition may include updated firmware for the ECU, and the reporting application is configured to be executed by the ECU after the updated firmware is installed in the ECU.
