摘　　要：汽车启动瞬间,整车电源电压波动剧烈。整车厂要求在这种电源波动情况下,整车电子产品需要有相应的保护措施,确保低压及电源振荡时工作性能仍然符合预期。传统的验证电子产品耐受电源电压干扰的性能需要实验资源支持,这给项目开发成本和时间带来负担。仿真验证产品电性能是传统设计验证方法的一个有力的补充。仿真验证的关键是要建立合乎规范和标准的启动电压激励模型。本文结合福特定义的汽车发动机冷、热启动时的电压波形,阐述了这类电压激励源模型的基本原理,建模和仿真方法。最后指出了电压激励源模型在验证电器模块电气性能的前瞻作用及其发展趋势。The vehicle power supply voltage fluctuates violently at the moment the vehicle starts.Vehicle manufacturers require that under such power fluctuations,vehicle electronic products need to have corresponding protection measures to ensure that the working performance of low voltage and power supply oscillations still meet expectations.The traditional verification of the performance of electronic products withstanding power supply voltage interference requires experimental resources to support,which brings burdens to project development costs and time.Simulation to verify the electrical performance of products is a powerful supplement to traditional design verification methods.The key to simulation verification is to establish a starting voltage excitation model that meets specifications and standards.Combining the voltage waveforms defined by Ford during cold and hot start of automobile engines,this paper expounds the basic principles,modeling and simulation methods of this type of voltage excitation source model.Finally,the forward-looking role and development trend of the voltage excitation source model in verifying the electrical performance of electrical modules are pointed out.
