With the sustainable development of the national economy in our country, the industry of auto has entered a new period in our country. Auto possession has increased unceasing, more and more people have their own cars, the demand for cars is higher and higher with people. Especially on the area of north in the low temperature on the winter, how to ensure that in low temperature environment better driving vehicle. To ensure the comfortableness, safety, dynamic property and economy, has become a concern of the people.This paper is for passenger cars to achieve work limit of the standard of requirements, in view of the cold areas use the characteristics of passenger vehicles in our country, and present the technical connotation. And both home and abroad present situation and the development tendency. Strengthen the passenger car for low temperature test standards, In order to improve the service life of the machine, and reduce wear passenger vehicles and failure, thus, improve the dynamic performance of passenger car, economy and safety. In the industry of relevant standards and standardization of the objective demand, according to ensure that international trade as a fair competition, maintain the normal order of the market, the communication of international economic cooperation bridge, the maximum maintenance automobile industry in our country in international interests. This article through to the passenger vehicles in the low environment and ice snow way the impact on the way to the analysis and research of the modeling method for passenger cars of car simulation, and combining with actual test results, preliminary passenger car for low temperature performance test specification, and gradually improve is, make it become the automobile industry standards of low temperature environment.Another the emphasis in this article is to establish the standard of low temperature environment farms, makes the test vehicle can better commissioning, and through the test of passenger vehicles in the experiment, setting passenger vehicles in the low temperature environment static and dynamic tests of the test of test methods, test method and result according to, make a fit their product characteristics of the standard, and screened accord with the situation of standard system in China.
