As with so many things, it all depends..... If your patent is describing an electrically assisted power steering system, then the angular position (as transmitted by an encoder) of the steering wheel (and probably angular velocity as well) will generate an output to be associated with a numerical data file stored in the steering logic system defining the position of the rack and pinion, quite possibly for each individual wheel (since their angles are not the same). Ideally, there would be a 1:1 correspondence between the steering wheel and the road wheels, but in reality slippage always occurs, especially when the turning circle (braquage) is tight. So, for "réferentiel", lookup table, reference file or reference data(file) should do it. But the remainder of the text should reveal more clues.
