1. A method for managing the sporadic anomalies of a power system of a motor vehicle, said system comprising a computer and a set of sensors, said computer comprising a memory area and being configured to receive measurements made by the sensors of the set of sensors and to detect anomalies on the basis of the measurements received, the anomalies of the system being defined in a predetermined list of sporadic anomalies at a given instant, said method comprising:
a) detecting an anomaly,
b) measuring a duration of the detected anomaly,
c) verifying a presence of the detected anomaly in the predetermined list of sporadic anomalies,
d) incrementing an occurrence counter when the measured duration is less than a predetermined duration threshold, and when the detected anomaly is present in the predetermined list of sporadic anomalies at the current instant,
e) confirming the detected anomaly as a sporadic anomaly when the value of the occurrence counter is greater than a predetermined occurrence threshold, and
f) operating the power system of the motor vehicle based on the predetermined list of sporadic anomalies updated with the confirmed sporadic anomaly.
