摘要： 2022 年 1 月 1 日正式实施了中国新车评价规程（CNCAP）2021 版标准，新增了中国 独有的对二轮踏板车的自动紧急制动（AEB）试验要求。基于 CNCAP2021 版中对二轮踏板 车的 AEB 试验要求，结合车辆制动系统特性，分析并计算出为满足该场景试验得满分的要求， AEB 系统触发需要的碰撞时间（TTC），并实车测试验证该 TTC 时间。根据所需要的碰撞时 间，结合实际二轮电动车与车辆的碰撞场景，及二轮电动车的制动性能，分析并实际模拟测 试，得出了 AEB 系统在实际使用中，不能完全与 CNCAP 完全一样的策略，需要根据实际的 复杂情况细化场景中车辆及二轮车的各种参数及二轮电动车驾驶行为，以提高车辆触发 AEB 的客户体验。

Abstract: January 1st 2022, the standard CNCAP 2021 edition has implemented, and there is a Chinese unique scenario test that autonomous emergency braking (AEB) to two-wheel electric bicycle. Based on the requirement of the test, and combined the character of the vehicle brake system, analyzed and calculated the requirement of full score of the test, and produced the result of the AEB trigger TTC. And then verified the TTC by real vehicle test. Accorded the TTC and AEB trigger strategy, and combined the collision scenario of the two-wheel electric bicycle and vehicle, and the character of the two-wheel electric bicycle brake system, furtherly produced the result form analysis and test that, it doesn't fit very well that use the strategy and TTC of AEB in the real road scenario. It needs more meticulous strategy based on the complex scenario of the character of the vehicle and the two-wheel electric bicycle and the operation of the two-wheel electric bicycle, to improve the customer experience of AEB system.
