Latch circuit and vehicle control system

The invention discloses a latch circuit and a vehicle control system. The latch circuit comprises a logic control module, a status latch module and an output control module, wherein the input end of the logic control module is connected with a processor, and the output end of the logic control module is connected with the input end of the status latch module; the processor outputs a logic control signal to the logic control module, so that the logic control module controls the status latch module to latch a first control signal; the output end of the status latch module is connected with the input end of the output control module so as to input the first control signal to the output control module; and the output control module outputs a second control signal under the effect of the first control signal, and the second control signal is used for controlling vehicle parts. When the processor normally works, the latch circuit latches the input signal of the output control module; and when the processor is abnor
