Abstract
The invention relates to a method for determining the absolute angular position .theta. of a steering wheel (2) of a motor vehicle with respect to the chassis thereof comprising an initial procedure for determining whether a detected binary sequence is non-repetitive and, if yes, to test whether an estimate makes it possible to discriminate the absolute angular position of a encoder (1) in the case when the binary sequence is non-repetitive on a sector and to discriminate the absolute angular position of the steering wheel (2) .theta..sub.2 corresponding to said non-repetitive binary sequence; if no, to test whether an estimate makes it possible to discriminate the absolute angular position .theta..sub.3 of the steering wheel corresponding to said binary sequence.
