摘　　要：分析并排除汽车电子电路中的潜电路成为提高汽车电子电路可靠性的重要手段。无效路径的剔除是电子电路潜电路分析技术的关键技术之一。基于电路元件特性及基本电路原理,提出了改进的无效路径剔除通用方法,从而保证后续潜电路判定的准确性。并用此方法对汽车部分控制电路进行了潜电路分析,验证了该方法的可行性和正确性。Sneak circuits analysis and excluding of vehicle electronic circuits have become an important means to improve the reliability of the vehicle electronic circuits. Invalid paths excluding is one of the key technologies in sneak circuit analysis tech nique. The paper puts forward the improved general method of invalid paths excluding based on the characteristics of circuit compo nents and the basic circuit principles in order to ensure the accuracy of sneak circuits judge in subsequent circuits. And in this paper, the feasibility and validity of this method have been verified through sneak circuit analysis for electronic circuits of vehicle.
