Vehicle low speed rear-end impact is a familiar traffic accident type. In order to prevent the occupants＇ cervical whiplash injury in this accident, different countries are promoting the development of passive safety technologies. This paper analyses similarities and differences of the test methods, scoring methods and assessment systems of Chinese, European, Japanese and American whiplash test programs.

The results show that although various assessment systems have differences, but assessment results have high consistency. The C-NCAP assessment score is higher than the others.%汽车低速后碰是一种常见的交通事故。为防止该事故中乘员颈部挥鞭伤，各国都在促进被动安全技术的发展。该文对比了中国、欧洲、日本和美国不同鞭打试验程序在试验方法、评分方法和评分体系的差异。2012新版中国新车评价规程（C-NCAP）将鞭打试验纳入评价体系，它不同于欧洲新车评价规程（Euro-NCAP）、日本新车评价规程（J-NCAP）和美国公路安全保险协会（IIHS）的规程。用上述各评价体系和评分方法，对同一组试验数据进行评分，把评分结果进行3分制转换，然后进行分析。结果表明：上述各评价体系虽然有差异，但评价结果具有高度的一致性。C-NCAP评价得分高于其他体系评价得分。
