CIRCUIT, METHOD AND STORAGE MEDIUM FOR CONTROLLING FAILURE OF VEHICLE MCU

A circuit for controlling failure of a vehicle MCU includes: a failure state detector, configured to monitor the state of a MCU circuit in real time; 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 the normal work of the driving controller.
