摘要 美国、欧洲和日本的汽车排放法规是当今世界上的3个主要法规体系。对主要法规体系的FTP-75,US06,SC03,NEDC,JC08 5种法规工况从速度、加速度以及两者的联合分布方面进行了研究和分析。研究表明:FTP-75,SC03,JC08工况点主要分布在低于60 km/h的中低速度区间内;US06工况点主要分布在80 km/h以上的高速区间内;NEDC工况点主要分布在匀速工况速度点;US06工况加速度分布范围最大,为-3.06~3.73 m/s^2,其最大加速度值(3.73 m/s^2)也最大;5种工况在高速工况比较平缓,中低速工况下加减速更频繁。该研究为我国制定相应测试工况提供了一定依据。 Light-duty vehicle emission regulations in the United States, Europe and Japan are the three major regulatory systems in the world. Five regulation test cycles including FFP-75, US06, SC03, NEDC and JC08 are studied anti analyzed hy speed distribution, acceleration distribution and joint distribution between speed and acceleration in this paper. The research shows that the main points of FTP-75, SC03 and JC08 are distributed in middle and low speed area which is lower than 60 km/h, while the main points of US06 cycle are distributed in the high speed area which is higher than 80 kin/h, and the NEDC points are mainly distributed in unifimn speed area. The acceleration of US06 cycle range is from -3.06 m/s^2 to 3.73 m/s^2, and the maximum acceleration is 3.73 m/s^2. It is relatively flat in the high speed driving condition of the five regulation test cycles, and the operation of acceleration and deceleration is more frequent in middle and low speed driving ranges. This study provides the basis for stipulating Chinese test cycles.
