Abstract: Abstract: 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 whiplash
test is added to China New Car Assessment Program (C-NACP) of 2012 new version which is different from
European New Car Assessment Program (Euro-NCAP), Japanese New Car Assessment Program（J-NCAP） and
that of the American Insurance Institute for Highway Safety (IIHS). This paper scores the same test data based
on the above scoring methods and assessment systems, transforms the scoring results into the 3 points system
and analyses the results. 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.
