Definitions

  • the present invention relates to the field of mechanical rotating systems, and more particularly the rotation detection systems.
  • the patent application FR 2 867 450 describes a method and a system for determining the angular position of the crankshaft of an internal combustion engine. For this, a sound wheel provided with incremental angular marks is integrally connected to the crankshaft. An angle sensor makes it possible to detect the successive passage of the angular lairs. The angle sensor has two units each capable of detecting the passage of the angular lairs. Depending on the offset between the two signals, it is possible to determine the direction of rotation of the disk and thus of the crankshaft.
  • Patent application FR 2 879 750 describes a method and a device for determining the direction of rotation of a wheel.
  • the device for detecting the direction of rotation of a wheel furthermore comprises at least one memory containing an electronic signature serving as a stored signal for the correction of the speed measurement noise signal by the means of determining the rotation speed of the wheel.
  • a wheel and at least one rotational direction change analyzer capable of determining a change in the direction of rotation of the wheel when the level of a corrected speed measurement noise signal received from the rotational speed determination means d a wheel passes a stored threshold level, the analyzer of the direction of rotation of the wheel emitting a signal of direction of rotation of the wheel following the reception of at least one logic signal for changing the direction of rotation of the wheel from a change of direction analyzer.
  • a method for detecting the direction of rotation of a wheel comprising a means for determining the speed of rotation of a wheel comprising a rotating part comprising angular marks and integrally connected to the wheel, and a part non-rotating device comprising a sensor capable of emitting at least one signal depending on the passage in succession of the angular marks during the rotation of the rotating part, the means for determining the speed of rotation of a wheel being able to deliver a signal of speed measurement noise corrected according to a stored signal.
  • the noise level of said at least one corrected speed noise signal is compared with a stored threshold level to determine the direction of rotation of the wheel.
  • the angular marks 3 have a circular path centered on O 2 .
  • FIG. 2 Such a situation is illustrated in FIG. 2, on which is represented a rotating part 1 whose shape and dimensions differ from the circular shape, leading to obtaining a shape of ellipse of large radius R2 and small radius Rl.
  • the elliptical character of the rotating part 1 has been deliberately exaggerated in order to be more perceptible.
  • FIG. 4 describes the method of calibrating digital signatures.
  • step 8 the digital signatures are acquired.
  • FIG. 5 shows an exemplary device for determining the direction of rotation of a wheel.
  • the analyzer 17 monitors the level of the corrected speed measurement noise signal and compares it to a stored threshold level.
  • the stored threshold level is defined as a signal level for discriminating a corrected speed measurement noise signal by an appropriate correction of a speed measurement noise signal corrected by an inappropriate correction.
  • the noise level is low.
  • the angular marks follow one another in the same way and the placement defects of said marks at the origin of the received signal correspond to those at the origin of the signature.
  • the correction being adapted, the measurement noise is reduced.
  • the analyzer 17 can then emit a detection signal of the direction of rotation of the wheel matching the direction of rotation of the wheel during the registration of the signature.
  • the noise level is high.
  • the angular marks follow one another in a different way and the placement defects of said marks at the origin of the received signal do not correspond to those at the origin of the signature. Since the correction is not adapted, the measurement noise increases.
  • the device By using the variations of the speed measurement noise signal level, corrected so as to use the manufacturing defects as a unique signature for each device, the device has few sources of error which can distort the determination of the direction of rotation of the device. a wheel.
  • the use of two simultaneous signals makes it possible to raise ambiguous cases and to obtain a reliable detection of the direction of rotation of a wheel.
  • the device does not require additional sensors and does not use expensive technologies in the detection member while being a very robust measuring device.
  • the determination device thus makes it possible to reliably and inexpensively determine the direction of rotation of a wheel.
