论文摘要
装有传感器，执行器和电子控制单元（ECU）的现代车辆可以分为几个称为功能工作组（FWGS）的操作子系统。这些FWG的示例包括发动机系统，变速箱，燃油系统，制动器等。每个FWG都有相关的传感器通道，可以计算车辆操作条件。这些数据丰富的环境有利于预测维护（PDM）技术的发展。削弱各种PDM技术的是需要稳健的异常检测模型，这些检测模型可以识别出明显偏离大多数数据的事件或观察结果，并且不符合正常车辆操作行为的明确定义的概念。在本文中，我们介绍了车辆性能，可靠性和操作（VEPRO）数据集，并使用它来创建一种基于多阶段的异常检测方法。利用时间卷积网络（TCN），我们的异常检测系统可以达到96％的检测准确性，并准确预测91％的真实异常。当利用来自多个FWG的传感器通道时，我们的异常检测系统的性能会改善。
A modern vehicle fitted with sensors, actuators, and Electronic Control Units (ECUs) can be divided into several operational subsystems called Functional Working Groups (FWGs). Examples of these FWGs include the engine system, transmission, fuel system, brakes, etc. Each FWG has associated sensor-channels that gauge vehicular operating conditions. This data rich environment is conducive to the development of Predictive Maintenance (PdM) technologies. Undercutting various PdM technologies is the need for robust anomaly detection models that can identify events or observations which deviate significantly from the majority of the data and do not conform to a well defined notion of normal vehicular operational behavior. In this paper, we introduce the Vehicle Performance, Reliability, and Operations (VePRO) dataset and use it to create a multi-phased approach to anomaly detection. Utilizing Temporal Convolution Networks (TCN), our anomaly detection system can achieve 96% detection accuracy and accurately predicts 91% of true anomalies. The performance of our anomaly detection system improves when sensor channels from multiple FWGs are utilized.
