STRATEGY FOR THE REPLACEMENT OF A DETACHED WHEEL UNIT DETACHED IN A TPMS SYSTEM FOR CONTROLLING THE PRESSURE OF THE TIRES OF A MOTOR VEHICLE

摘要

The invention relates to a method and a TPMS system comprising a central unit (2) and wheel units (3a-3d), • each wheel unit (3a-3d) comprising a pressure sensor (5a-5d), and regularly transmitting pressure measurements and radial acceleration measurements to the central unit, the latter being used to calculate a detachment parameter for the wheel unit, • the central unit (2) comprising a test module ( 2d) configured to determine whether each wheel unit is in an off state or in an operational state, and a reset module (2e) configured to toggle the state of a wheel unit from the detached state to the operational state if: - since the wheel unit has been declared detached, a pressure less than or equal to a reference atmospheric pressure has been measured while the vehicle was stationary, and if - after this stop, at least l one of the following criteria is verified: para detachment meter did not reach a nominal detachment threshold at first taxiing; an attachment index corresponding to a particular form of a measurement signal of the wheel unit has been detected under specific evaluation conditions.
