🤖 AI Summary
Existing mission profile modeling approaches for electric and autonomous vehicles provide only aggregated histograms of single stress parameters (e.g., temperature or voltage), lacking multidimensional coupling, temporal evolution, and full-lifecycle characterization. To address this, we propose a novel mission profile modeling framework grounded in functional temporal modeling, which jointly captures the dynamic evolution of multiple stress parameters—including temperature, humidity, and voltage. The framework supports configurable time-granularity sampling and user-defined quantile analysis, and embeds anomaly detection and data integrity protection mechanisms to ensure compliant, trustworthy data sharing across the supply chain (suppliers–OEMs–end users). For the first time, our framework enables high-fidelity, quantifiable, multi-stress-coupled mission profile modeling with built-in security and collaborative capabilities.
📝 Abstract
Mission profiles cover the conditions that a component, e.g., an electronic component of a vehicle, is exposed to during its lifecycle. Currently, these profiles typically provide descriptive summaries, such as histograms, of single stress parameters like temperature, humidity, or voltage. This is highly aggregated information. New requirements for electric and autonomous driving cars require much more information how applications are used. In this work, we present a new approach for mission profiles which contains detailed usage information. We suggest a functional description over time, which allows joint modeling of various characteristics such as temperature, humidity, and voltage. The entire lifecycle history is covered, and the method can control the temporal resolution, i.e., the level of details of a mission profile. As a result, more accurate mission profiles can be generated, user quantiles can be derived, and usage outliers can be identified. This model establishes a framework to exchange usage data between suppliers, original equipment manufacturers (OEMs), and end customers while data integrity and protection are assured.
