The invention relates to the technical field of electric automobiles, in particular to a circuit device for system failure protection, a system failure protection method and an automobile, and the circuit device comprises an input end module which is used for receiving a control signal; the transistor logic network module comprises at least two transistors, the conduction state of each transistor is independently or jointly controlled by a control signal, and the transistor logic network module realizes a failure detection and response mechanism through logic combination based on the control signal; the delay circuit module is used for starting a preset delay time when a preset failure condition is detected, and changing the output state of the circuit after the delay is finished; and the output end is used for keeping low-level output when the system works normally, outputting a high level when the system fails, and then outputting the low level after the delay is finished. When the system encounters a failure condition, the system can quickly respond and effectively prevent emergency situations such as power interruption caused by the failure of the system, so that the safety in the driving process is ensured.

    本发明涉及电动汽车技术领域,具体涉及一种用于系统失效保护的电路装置、系统失效保护方法及汽车,包括:输入端模块,用于接收控制信号;晶体管逻辑网络模块,包括至少两个晶体管,每个晶体管的导通状态由控制信号独立或联合控制,晶体管逻辑网络模块基于控制信号通过逻辑组合实现失效检测与响应机制;延时电路模块,用于在检测到预定的失效条件时,启动一段预定的延时时间,并在延时结束后改变电路的输出状态;输出端,用于在系统正常工作时保持低电平输出,在系统失效时,先输出高电平,随后在延时结束后输出低电平。本发明在系统遭遇失效状况时,能够迅速响应并有效预防因系统失效而引发的动力中断等紧急情况,从而确保行车过程中的安全性。
