Vehicular Data Collection Controller Mode Switching

Solution Overview

Problem

Current methods for transmitting vehicle data via cellular networks are cost-prohibitive and consume excessive bandwidth due to the large volume of data produced by millions of vehicles, necessitating a reduction in data transmission frequency.

Innovation Solution

Implementing a data collection system with a controller that switches between normal and abnormal modes based on event triggers, transmitting data at a less frequent rate during normal operation and more frequently during abnormal conditions, thereby conserving bandwidth and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data is transmitted at normal frequency continuously, then complete data monitoring is maintained, but bandwidth consumption and operational costs increase significantly

Engineering Contradiction:

Improvedata monitoring completenessVSAvoidbandwidth consumption

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent implements dynamic transmission frequency adjustment based on vehicle operational state. The system transitions between normal mode (lower transmission frequency) and abnormal mode (higher transmission frequency) depending on whether fault conditions are detected, thereby optimizing bandwidth usage while maintaining monitoring reliability when needed.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the data transmission frequency parameter based on operational conditions. In normal mode, transmission occurs at a lower frequency to conserve bandwidth, while in abnormal mode (when faults are detected), transmission frequency increases to ensure complete data monitoring and rapid fault reporting.

Inventive Principle:

Principle #35Parameter changes

2Loss of energy

If data transmission frequency is reduced to lower costs, then operational expenses decrease, but fault detection timeliness may be compromised

Engineering Contradiction:

Improveoperational costVSAvoidfault detection timeliness

Core Design Contradiction:

Loss of energyVSLoss of time

Solution Approach 1:

The system continuously monitors vehicle parameters and uses feedback to determine when to switch transmission modes. When fault conditions are detected through parameter analysis, the system automatically transitions to abnormal mode with increased transmission frequency, ensuring timely fault detection while maintaining cost efficiency during normal operation.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The transmission frequency is dynamically adjusted based on real-time vehicle condition monitoring. The system maintains lower transmission frequency during normal operation to reduce costs, but rapidly increases frequency when fault conditions are detected, ensuring timely fault reporting without unnecessary cost expenditure during normal conditions.

Inventive Principle:

Principle #15Dynamics

If transmission frequency increases during abnormal conditions, then fault reporting accuracy improves, but bandwidth consumption increases

Engineering Contradiction:

AI summary

Methods and systems are provided for vehicular communications. The systems include a server and a controller in a vehicle. The controller is configured to receive data from vehicular components and transmit the data to the remote server. In a normal mode, the data is transmitted in accordance with a normal frequency of events, while in an abnormal mode, the data is transmitted in accordance with an abnormal frequency of events. The abnormal frequency is different from the normal frequency. The abnormal mode is set in response to an event trigger denoting a fault of at least one component.
