the alarm information generating unit is used for generating and outputting corresponding alarm information if the current times of activating the ECU is not less than the preset activation times;
wherein the re-flashing unit includes:
and the first re-flashing subunit is used for re-flashing the required data by using the activated ECU and returning to execute the ECU state detection unit if the ECU is successfully activated and the current number of times of activating the ECU is less than the preset activation number.
8. The apparatus of claim 6, wherein the control unit comprises:
and the control subunit is used for calling a preset safe access operation program and controlling the ECU to enter a safe access service if the state of the ECU is detected to be the death state.
9. An electronic device, comprising: the system comprises a processor and a memory, wherein the processor and the memory are connected through a communication bus; the processor is used for calling and executing the program stored in the memory; the memory for storing a program for implementing the ECU flush fault handling method according to any one of claims 1 to 5.
10. A computer-readable storage medium having stored therein computer-executable instructions for performing the ECU flush fault handling method of any one of claims 1-5.
