摘　　要：汽车在启动瞬间电源电压的变化较为复杂,该电压的变化需要车载电子模块设计出合理的电源管理策略,目前针对此电源管理策略缺乏有效的验证手段,提出了一种基于Lab VIEW的汽车电源模拟测试系统设计。通过利用示波器采集不同车型在不同研发阶段的起动瞬间的整车电源电压做为测试的输入,利用Lab VIEW以及GPIB总线,实现对可编程程控直流电源的控制,输出预设的电源模拟测试波形,并最终通过NI的Teststand实现了系统的自动化测试。经过验证,测试系统在某主机厂的娱乐系统测试中得到了很好的应用。The power change when starting a car is very complicated. It requires an optimum strategy of power management, which is deficient now. The LabVIEW based test system design is introduced, which can collect and monitor the change of power when the vehicle is starting. The system uses the LabVIEW software to realize the control of DC power source via GPIB. The system also realizes auto test via TestStand. The test system and its realization has been introduced. And the whole system has been applied in some entertainment system in an automotive company.
