基于国内工况的整车制动性能山路试验

Mountain Path Test of Vehicle Braking Performance Based on Chinese Customer Conditions

欧美车企在奥地利大格洛克纳山模拟用户工况进行整车制动性能试验,日本车企在日本本土也有相应的试验道路,以实际道路模拟用户驾驶工况的方法进行制动性能的开发验证。国内关于山路制动性能测试,暂未形成统一的试验方法。文章以国内实际道路为基础,结合奥地利大格洛克纳山试验方法和国内用户工况,参考中国汽车技术研究中心在全国乘用车制动使用情况与工况研究中对国内用户制动减速度、制动负荷系数、制动频度等数据的总结,进行整车试验数据采集、验证,从而探索出一种适应中国用户的制动性能山路试验方法,具有重大的实际意义。

European and American automobile companies conduct vehicle braking performance tests in the Great Glockner Mountain in Austria under simulated user driving conditions.Japanese auto companies also have corresponding test roads to develop and verify braking performance by simulating driving conditions of users on actual roads.In China,there is no unified test method for braking performance test on mountain road.In this paper,based on the domestic actual road,combining with the Austrian Great Glockner test method and user condition,and referring to the summary of braking deceleration,braking load coefficient,braking frequency in the research on braking of passenger vehicles in China by China Automotive Technology and Research Center.It is of great practical significance to collect and verify the vehicle test data,so as to explore a kind of test method of braking performance in mountain road which is suitable for Chinese users.
