Claim:
1. A method for determining identifiers (ID) of wheel units of a vehicle and positions relative to the vehicle of the wheels on which said wheel units are fitted, the vehicle being equipped with a speed sensor for each wheel, each wheel unit being equipped with means for transmitting at a predetermined angular position of the corresponding wheel around its axis ( 18 ) a message including the identifier of the wheel unit, a central processing unit receiving said message and information from said speed sensors, said method comprising the following steps: a) counting, for each identifier, of a number “nt” of receptions of said identifier, b) statistical processing of the numbers “nt” in order to determine from among all the identifiers received those which are statistically indicated to be the identifier of one of the wheel units of the vehicle, the identifiers becoming candidate identifiers for the vehicle, the statistical process ending when the number of the candidate identifiers is at least equal to the number of wheels of the vehicle, and c) determining that each candidate identifier is the identifier of a particular wheel unit if said candidate identifier meets a predetermined criterion relating to at least one instant of reception of said candidate identifier and to the angular position of a particular wheel at said instant, and assigning to the corresponding particular wheel the position relative to the vehicle of the speed sensor supplying said angular position, wherein step c) comprises steps cb 1 ) to cb 10 ), in which at step cb if yes in step cb at step cb at step cb at step cb at step cb at step cb at step cb at step cb at step cb
