Process for estimating the motion phase of an object

Process for estimating the motion phase of an object, comprising:

• acquiring experimental data from measurements of physical quantities by means of at least one sensor associated to the object;
• using the measurement data from the at least one sensor to produce a first reliable estimation of a motion phase with a first range of values by a first method, presenting a first predetermined reliability;
• using the measurement data from the at least one sensor to produce at least one additional estimation of a motion phase with an additional range of values with a different method for the at least one additional estimation of a motion phase, the different method presenting a different predetermined reliability;
• arranging the ranges of values representing estimations of a motion phase in order of decreasing reliability of the corresponding methods;
• comparing each additional range of values with the range of values corresponding to the previous method according to said order;
• choosing the additional range of values as a result range of values when the additional range of values lies within the range of values corresponding to one of the previous methods;
• applying the result range of values to precisely estimate the motion phase of the object;
• and
• reporting the results of the application,
• wherein the reported precisely estimated motion phase of the object facilitates characterizing the motion of the object.
