Solution Overview
Problem
Unmanned vehicles face safety hazards due to undetected faults in their software and hardware systems, leading to potential accidents when timely data transfer is impossible.
Innovation Solution
The implementation of a dual vehicle fault processing system where two devices monitor and share real-time data from the main system, allowing for consistent fault determination and control actions based on pre-configured authorities, ensuring robustness and safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single vehicle fault processing device is used, then the device complexity is low, but the reliability of fault detection is insufficient
Solution Approach 1:
The patent implements independent fault processing capabilities at each vehicle fault processing device, where both the first and second devices can autonomously perform fault detection and determination. This local quality approach ensures that each device has the necessary processing power and algorithms to reliably detect faults, while the system as a whole benefits from redundancy without requiring one device to be overly complex.
Solution Approach 2:
The fault detection system is segmented into multiple independent processing devices, each handling specific aspects of fault monitoring. The first vehicle fault processing device and second vehicle fault processing device operate as separate entities that exchange information, allowing the system to distribute the computational load and improve reliability through modular architecture.
2Loss of time
If real-time data sharing between dual fault processing devices is implemented, then the fault detection timeliness is improved, but the data transfer requirements increase
Solution Approach 1:
The patent extracts only the essential fault-related data from the complete vehicle system data stream for transmission between the first and second vehicle fault processing devices. By selectively extracting and transmitting only the critical parameters needed for fault detection rather than all available data, the system achieves timely fault detection while minimizing data transfer volume and network bandwidth requirements.
Solution Approach 2:
The system implements partial data sharing where each device transmits only the portion of data it has processed or that is relevant to its specific monitoring function. This partial action approach avoids the excessive data transfer that would occur if complete data sets were exchanged, while still providing sufficient information for reliable joint fault determination.
Data Source
AI summary
A method for processing vehicle fault, the method includes obtaining, by a first vehicle fault processing device, first data information of a main system of a vehicle in real time, obtaining second data information of the main system sent by a second vehicle fault processing device, and sending the first data information to the second vehicle fault processing device, so that the second vehicle fault processing device performs fault determination on the main system according to the first data information and the second data information; determining, by the first vehicle fault processing device, whether a fault has occurred in the main system according to the first data information and the second data information; and performing, by the first vehicle fault processing device, corresponding control on the vehicle according to a pre-configured control authority if the fault has occurred in the main system.
