The invention belongs to the technical field of vehicle control, and discloses a redundancy architecture for realizing vehicle safety control, the redundancy architecture comprises a redundancy blocking circuit, a PWM driving assembly and a function safety assembly, the redundancy blocking circuit comprises U1A, U1B, R1, R2, R3 and U2, the PWM driving assembly comprises a driving IC, and the function safety assembly comprises a processing circuit, an MCU1 and an MCU2; the same enable signal can be controlled through multiple paths of signals, the two paths of MCU processing modules process detection signals in real time, when one path of processing circuit breaks down, a redundant circuit can bear the safety state of the system, and safety protection can be completed through the redundant design circuit under the condition that a vehicle breaks down; and a vehicle function safety state is realized.

    本发明属于车辆控制技术领域,且公开了一种实现车辆安全控制的冗余架构,包括冗余封锁电路、PWM驱动组件以及功能安全组件,所述冗余封锁电路包括U1A、U1B、R1、R2、R3、U2,所述PWM驱动组件包括驱动IC,所述功能安全组件包括处理电路、MCU1和MCU2;能够通过多路信号控制同一个使能信号,且两路MCU处理模块针对检测信号进行实时的处理,同时当一路处理电路故障时,冗余电路可以承担系统的安全状态,避免在车辆出现故障情况下,能够通过冗余设计电路完成安全保护,实现车辆功能安全状态。
