Abstract: With the development of China's automobile industry, a diversified pattern of automotive products has taken shape, and the accompanying product competition grows increasingly fierce. Especially in the field of automated manual transmission (AMT) commercial vehicles, automakers no longer regard "high load and high speed" as the sole objective in vehicle development. Instead, they place greater emphasis on the research of gear-shifting strategies to improve drivability, thereby boosting the competitiveness of similar products. The AVL-Drive drivability evaluation system mainly adopts subjective scoring and lacks objective test result indicators, which makes it difficult to satisfy the test demands of domestic complete vehicle development. This paper presents an evaluation and test method for the drivability of AMT commercial vehicles based on the AVLDrive system. The method intends to provide a basis for automaker designers and developers to improve vehicle drivability throughout the development process, empower industrial upgrading, and fill the research gap in this field.

摘要： 随着国内汽车工业持续发展，汽车产品多样化格局已然形成，行业产品竞争日趋激烈。 在机械式自动变速器（AMT）商用车领域，主机厂车型开发不再单一追求“多拉快跑”，而是 愈发重视换挡策略优化，以此提升车辆驾驶品质、增强产品市场竞争力，现阶段 AVL-Drive 驾驶性评价系统以主观评分为核心，缺乏客观测试指标，无法满足国内整车开发的测试要求。 文章基于 AVL-Drive 驾驶性评价系统，提出一套 AMT 商用车驾驶性评价测试方法，可为车 企研发人员优化车辆驾驶品质提供参考依据，同时助力行业产业升级，填补该领域相关研究 空白。
