Abstract: With the advent of the intelligent, connected, and electrified automobiles, intelligent connected vehicles have entered millions of households from experimental or research prototype vehicles. The longitudinal driving assistance function plays an important role in reducing the burden on drivers and improving driving safety and comfort. The objective testing and evaluation methods are mainly used for evaluating longitudinal driving assistance functions. Objective evaluation can effectively repeat testing and compare, but some indicators are too professional to be popularized to ordinary users. At the same time, they lack subjective experience and cannot effectively solve users' core demands. Thus objective evaluation can not evaluate the relevant function comprehensively. Therefore, this article proposes a longitudinal driving assistance subjective evaluation method based on closed field testing, combining existing subjective evaluation methods for vehicles and testing scenarios. This method is applied to real vehicle evaluation examples. This article also provides a reference method for the subjective evaluation of intelligent driving related functions.

Key words: the longitudinal driving assistance function; subject evaluation; the closed field testing; the intelligent driving

摘要： 随着汽车智能化、网联化、电动化时代的来临，智能网联汽车已经从试验车或研究性。 样车走进了千家万户。纵向驾驶辅助功能在减轻驾驶员负担，提升驾驶的安全性和舒适性方 面发挥了重要作用。目前针对纵向驾驶辅助功能主要采用客观测试评价方法，但客观评价虽 能有效地重复测试且进行对比，但部分指标过于专业，无法向普通用户普及，同时缺少人的 主观体验，不能有效解决用户的核心诉求，进而不能对相关功能进行全面地评价。因此针对 客观评价方法的不足，文章结合现有的车辆主观评价方法以及测试场景，提出了一种基于封 闭场地测试的纵向驾驶辅助主观评价方法，并将该方法应用到实车测评的实例中，同时也为 智能驾驶相关功能的主观评价的研究提供了一种参考方法
