Determination Of The Absolute Angular Position Of A Steering Wheel By Binary Sequences Discrimination

摘要

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 ) theta₂ corresponding to said non-repetitive binary sequence; if no, to test whether an estimate makes it possible to discriminate the absolute angular position theta₃ of the steering wheel corresponding to said binary sequence.
