Abstract

Standard driving cycles is the basis to obtain the vehicle type-approval energy consumption. However, for users, there is a gap between the type-approval results and their experiences. For manufacturers, limited number of test cycles cause sub-optimization related issues during the vehicle design and development; for testing organizations, deterministic test cycles lead to the risk of cheating in testing. Therefore, a novel double-filter method is proposed to generate multiple stochastic driving cycles that are energy consumption comparable. Using user data as reference, chassis dynamometer tests were designed for validation of the energy consistency. Results show that the maximum deviation from the user was 2.144%, and the minimum was only 0.465%. The method proposed enables customized families of test cycles, overcoming the limitations of deterministic, finite cycles, which contribute to vehicle economy optimization and provide a dependable foundation for energy consumption estimation for city transportation systems and related policy development.

一种双滤波器驱动循环生成框架，并进行了测功机测试和分析

标准行驶工况是获得整车型式认可能耗的依据。然而，对于用户来说，类型批准结果与他们的体验之间存在差距。对于制造商来说，在车辆设计和开发过程中，有限的测试周期导致了与次优化相关的问题；对于测试机构来说，确定性的测试周期会导致测试作弊的风险。为此，提出了一种新的双滤波方法来生成多个能耗可比较的随机驱动循环。以用户数据为参考，设计了底盘测功机试验，验证了能量一致性。结果表明，与用户的最大偏差为2.144%，最小偏差仅为0.465%。该方法克服了确定性、有限循环的局限性，实现了测试循环的定制化，有利于车辆经济性优化，为城市交通系统的能耗估算和相关政策制定提供了可靠的依据。

期刊介绍： Transportation Research Part D: Transport and Environment focuses on original research exploring the environmental impacts of transportation, policy responses to these impacts, and their implications for transportation system design, planning, and management. The journal comprehensively covers the interaction between transportation and the environment, ranging from local effects on specific geographical areas to global implications such as natural resource depletion and atmospheric pollution. We welcome research papers across all transportation modes, including maritime, air, and land transportation, assessing their environmental impacts broadly. Papers addressing both mobile aspects and transportation infrastructure are considered. The journal prioritizes empirical findings and policy responses of regulatory, planning, technical, or fiscal nature. Articles are policy-driven, accessible, and applicable to readers from diverse disciplines, emphasizing relevance and practicality. We encourage interdisciplinary submissions and welcome contributions from economically developing and advanced countries alike, reflecting our international orientation.
