Abstract
A method of determining the rotary, rotationally immobile or mobile, state of a vehicle wheel, according to which the signal delivered by an active motion sensor fitted to the wheel is analyzed instantly according to a procedure consists, firstly, at time t, in connecting the motion sensor to an analog circuit including at least one capacitor and interposed between the motion sensor and a first input of an electronic comparison element, so as to store in the capacitor reference value Vrepresenting the value of the signal at t. Thereafter, the motion sensor is connected to a second input of the comparison element, to compare Vwith a value Vrepresenting the value of the signal at time t, and to deliver a diagnostic signal representing either a rotationally immobile state of the wheel when V=V, or a rotationally mobile state of the wheel when V≠V
