Abstract
To compensate for the corruption of a memory of a computer communicating with several identical computers via a communication bus: prior to any communication between the computers, a distinct number is allocated (200) to each of the computers, said number being used by the computers to calculate an identifier to be included in data to be communicated; each computer, before sending or receiving data, performs (202) an initialization procedure; if, during this initialization procedure, a computer detects (204) that its memory is corrupted, it searches (210) on the communication bus, over a predetermined duration (208), for the identifiers included in the data which travel around the bus; and if, after elapsing (212) of this predetermined duration, the computer having a corrupted memory has found the identifiers of all the computers except one, it determines (214) the missing identifier, deduces therefrom the corresponding number and self-assigns it (216), so as to be able to communicate with the other computers. Application to motor vehicles.
