摘要： The invention concerns a device for measuring on a rotating shaft (1) the torque of a steering column located in the plane of said shaft cross section (A) and a detector which delivers a signal proportional to the shaft (1) torsional moment resulting from the relative angular offset of the field generator with respect to the detector. The invention is characterised in that a first electronic circuit (14) within the steering column is fixed to a support (17) concentrating the magnetic field and moves in front of the generator of said field (12) jointly with mechanical angular return means (13) of the rotating shaft (1) two sections, and bearing measuring sensors (15) delivering signals to a second electronic circuit (20) processing said signals, outside the steering column for delivering signals actuating receiving devices via a transfer box (28).

摘要： The invention concerns a device for multiplying the resolution of a speed and displacement sensor consisting of a mobile multipolar magnetic encoder facing two fixed analog sensors, delivering sinusoidal signals (S1, S2), out of phase by π/2 comprising: a generator (3) of 2n sinusoidal signals (Si), of the same amplitude (A) as the signals (S1, S2) out of phase by π/n; an analog multiplexer (5) delivering a signal (S) consisting of 2n successive portions of signals (Si); means (6) for acquiring the maximum envelope (E) of signals (Si); two generators (7, 10) of threshold (Li) and (Lj) of commutation proportional to the envelope (E); two comparators (8, 11) of signal (S) with thresholds (Li) and (Lj), delivering binary signals (Ai) and (Bj); two means for combining (9, 12) the binary signals (Ai) and (Bj) each delivering a signal of 2m*n periods in the interval of one period of one of the sensors.

摘要： The invention concerns a digital position sensor, whereof the device processing input signals (S1 and S2), sinusoidal, in quadrature, of equal maximum amplitude (A0), centred on a common mean value (C0), and of duration equal to one rotation, generates, from said signals, 2 m-1 sinusoidal signals (S¿i?), of the same amplitude (A0), centred on the same mean value (C0) and successively out of phase by 2π/2?m-1¿, delimiting 2m identical sectors (P¿i?) representing the m high order bits of the digital output signal (bn-m+1, ....., bn); for each sector (Pi), fine interpolation means (4) break down the input signals (S1 and S2) specific to each sector for generating the (n-m) low order bits of the signal (b1, ....., bn-m), the set of the sensor output digital signals (b1....., bn) representing the absolute position of the rotating member.
