1. A circuit for controlling failure of a vehicle MCU, at least comprising:
a failure state detector, configured to monitor information output by an MCU circuit in real time to detect whether the MCU circuit is in a failure state;
a maintaining voltage signal generator, configured to: when the MCU circuit is detected to be in a failure state, convert a voltage from an ignition coil of a vehicle to form a failure maintaining voltage signal; and
a driving maintainer, configured to output the failure maintaining voltage signal to a driving controller of each load in the vehicle so as to maintain normal work of the driving controller.
