Patent ID: 7930929

Claim:
A method of transmitting information making it possible to monitor an operation of an internal combustion engine, comprising the steps consisting of: measurement of an angular position of a crankshaft by means of an absolute position sensor provided with a digital output, and transmission at a frequency f 1 to an engine control unit of the measured angular position information, encoded in a data string containing N1 bits, and transmission at a frequency f 2 of the measured angular position information, encoded in a data string containing N2 bits, the number N2 of bits being greater than the number N1, the frequency f 2 being less than or equal to the frequency f 1 , wherein the measurement step is carried out by a single absolute position sensor measuring the angular position in at least N2 bits, the step of transmission of the angular position encoded in a data string containing N1 bits being carried out by the truncation of the data string containing N2 bits.
