Circuit, method and storage medium for controlling failure of vehicle mcu

A method for controlling failure of a vehicle MCU, being implemented by a circuit for controlling failure of a vehicle MCU 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;
• wherein the method comprises the following steps:
• Step S10:
• monitoring information output by the MCU circuit in real time to detect whether the MCU circuit is in a failure state;
• Step S11:
• when the MCU module circuit is detected to be in a failure state, converting a voltage from the ignition coil of the vehicle to form a failure maintaining voltage signal;
• and
• Step S12:
• outputting the failure maintaining voltage signal to the driving controller of each load in the vehicle so as to maintain the normal work of the driving controller.

A non-transitory computer-readable storage medium having stored therein instructions that, when executed by a processor of a terminal, causes the terminal to perform a method for controlling failure of a vehicle MCU, the method comprising:
