Aiming at the safety accident of children mislocked in the car incurred the death, a reliability calculation method of vehicle safety device is proposed. In order to avoid the accident as far as possible, a device is used for the monitoring and alerting of living beings in the vehicle. So the device reliability becomes particularly important. In the study, the safety logic relationship of the device unit is clarified through the detailed analysis of the composition function and work flow of the device. Furthermore, this paper introduces the method of building the device reliability models, gives the equivalent models of solving the device reliability, and defines a series of solving functions of reliabilities. This paper also studies the calculation method of the reliability of the network equivalent model, that is, the calculation method of the network model decomposition method. Finally, an example of reliability calculation is given to show the effectiveness of the proposed method. The results show that the proposed method can obtain the reliability value of the device.
