摘　　要：研究了汽车电气系统的可靠性设计方法,通过计算出汽车电气系统可靠性指标,对已设计的电路进行可靠性建模、使用快速预计法检验可靠性指标,利用工程加权法进行可靠性分配、元器件选择,再通过可靠性预计来检验该电路的可靠性。以汽车上的双555电子防盗报警器电路为例,采用RELEX可靠性设计分析软件对该可靠性设计方法进行了实际的计算和应用,验证了该方法的可行性。The reliability design method for the electrical system of a ear is studied by the calculating the reliability indexes of the electrical system, modeling for reliability of the designed circuit, verifying the reliability indices with the rapid prediction method, selecting componeuts and allocating reliability, and verifying the reliability of the circuit through reliability prediction. Finally, with a double 555 circuit of the electronic immobilizer as an example, the feasibility of the proposed reliability design method is illustrated by actual calculation and application based on RELEX software.
