With the constant progress of auto safety technology，the development of occupant protection technology has become mature，improving the safety of occupant considerably. By contrast，the development of the pedestrian collision protection technology is still very slow. At present，the pedestrian collision protection technology has become the focus of the relevant researchers in the world. It has attracted attention of the governments，enterprises，and consumers. This paper introduces the history of the development of pedestrian collision and the relevant regulations and appraising methods of Europe，Japan，and China etc. and provides comparison of the regulations and appraising methods between China，Europe，and Japan （such as GB/T 24550-2009，ECE R 127，Euro NCAP，11-3-99，and JNCAP. Finally，it indicates the development trend of pedestrian collision protection technology and standard，giving the direction to the R&D of Chinese enterprises in this area.
