Method for testing a computer reset device

A method for testing, in situ and in operation, a reset device for resetting a computer, said device running at least one piece of reset software, said computer running at least one piece of control software in order to control a member, comprising an execution sequence and a verification sequence, the execution sequence being executed during the running of the piece of control software and comprising:

• incrementing a test counter,
• storing the test counter in a non-volatile memory,
• triggering a reset of the computer,
• the verification sequence being executed when starting the piece of control software and comprising:
• reading the test counter from the non-volatile memory,
• comparing the test counter:
• if the test counter is equal to its initial value there is no test result;
• if the test counter is equal to its initial value increased by 1, resetting the test counter, and the result of the test is positive;
• and if the value of the test counter is different, creating a “reset” error, and the result of the test is negative,
• wherein the execution sequence further comprises:
• storing a reset date in a non-volatile memory,
• and the verification sequence further comprises:
• reading the reset date from the non-volatile memory,
• determining a reset duration from the difference between the reset date and the current date, and
• comparing the reset duration with a maximum threshold:
• if the reset duration is greater than the maximum threshold:
• creating a “duration” error and the result of the test is negative.

• wherein the execution sequence further comprises an initial step of:
• verifying the state of the member, the other steps of the execution sequence being executed only when the member is inactive.
