Neural Network Input Storage Partitioning for Automotive Predictive Maintenance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automotive maintenance schedules are often inconvenient and fail to predict component failures in real-time, leading to potential safety hazards and unscheduled vehicle breakdowns, especially in autonomous driving systems where timely intervention is critical.
Innovation Solution
Implementing a system that uses artificial neural networks (ANNs), specifically spiking neural networks (SNNs), to analyze sensor data from vehicles to predict maintenance needs, allowing for proactive scheduling of maintenance services based on personalized operating habits and environmental conditions, thereby reducing the likelihood of breakdowns and enhancing safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional predetermined maintenance schedules are used, then maintenance services can be scheduled in advance, but the system cannot predict component failures in real-time leading to safety hazards and breakdowns
Solution Approach 1:
The system performs preliminary analysis by continuously monitoring sensor data and training neural networks to predict component failures before they occur. The ANN processes sensor inputs in advance to generate maintenance predictions, allowing the system to take proactive action rather than waiting for actual failures or relying on fixed schedules.
Solution Approach 2:
The system implements feedback loops where sensor data from vehicle operations continuously feeds into the neural network, which adjusts its predictions based on actual operating conditions. The maintenance predictions are fed back to update the monitoring system, creating a closed-loop system that improves predictive accuracy over time while enabling real-time responses.
2Measurement precision
If sensor data is continuously monitored and stored for ANN analysis, then predictive accuracy improves, but data storage requirements and processing complexity increase
Solution Approach 1:
The system extracts only the essential sensor data features that are most relevant for predicting specific component failures, rather than processing all raw sensor data. The neural network is trained to identify and extract key predictive features from sensor inputs, reducing the complexity of data processing while maintaining high prediction accuracy.
Solution Approach 2:
The monitoring system is segmented into modular components: sensor data acquisition modules, data preprocessing modules, neural network prediction modules, and maintenance scheduling modules. Each module handles specific tasks independently, reducing overall system complexity while enabling accurate predictions through coordinated operation of specialized components.

AI summary
Systems, methods and apparatus of optimizing neural network computations of predictive maintenance of vehicles. For example, a data storage device of a vehicle includes: a host interface configured to receive a sensor data stream from at least one sensor configured on the vehicle; at least one storage media component having a non-volatile memory; and a controller. The non-volatile memory is configured into multiple partitions (e.g., namespaces) having different sets of memory operation settings configured for different types of data related to an artificial neural network (ANN). The partitions include an input partition configured to store input data to the ANN. The sensor data stream is applied in the ANN to predict a maintenance service of the vehicle. The memory units of the input partition can be configured for enhanced endurance, cyclic sequential overwrite of a continuous input stream.
