The goal is to expose the energy management system (EMS) to extreme temperature and environment. This ensures the system will operate appropriately under stressed conditions. The vehicle test trips often compose of hot, cold, and altitude conditions. Because the test trips are sensitive to suitable weather conditions, using climatic chambers for extreme temperature testing has been used to supplement calibration process when seasonal constraints and production timing do not line up. In order to meet the F-series Euro II SOP in July, the process is to use exclusively climatic chamber for calibration and validation instead of territory test trips. 要标定全面的引擎和汽车性能参数,传统的方法是通过驾驶被测车辆进行一次道路三高试验来完成测试.目的是为了把汽车的发动机管理系统暴露在极端条件下(温度和环境).这保证了所有的系统在比较恶劣的环境下能够正常有效的运行.而这样的旅行常常包含高温,低温,高海拔条件.由于这样的旅行测试对气候条件非常敏感,因此当标定工作被季节或者产品开发时间所限制的时候,我们把环境仓测试当作普通标定过程的一种补充形式.为了达到 7 月份 F 系列发动机 欧 II 排放的标准,这次标定完全由环境仓来代替传统的自然环境标定过程. While territory test trips have certain benefits such as lower cost and expose vehicles to greater range of conditions, there are benefits to using climatic chamber. The benefits are: 和传统旅行标定方式拥有低成本,参数广泛全面等优点一样,环境仓标定方法也有自己的好处: 1) Controllability 可控性 It is easier to adjust the temperature/barometric pressure to the exact condition that is not always possible in actual vehicle test trip. In test trips, you are at the mercy...
