Abstract
A method and TPMS system including a central unit and wheel units. Each wheel unit including a pressure sensor, regularly transmitting pressure and radial acceleration measurements to the central unit. The latter used to calculate a detachment parameter for the wheel unit. A test module determines whether each wheel unit is in a detached or operational state. A return-to-service module toggles the state of a wheel unit from the detached to the operational state if: since the wheel unit was declared detached, a pressure less than or equal to a reference atmospheric pressure is measured while the vehicle was at rest, and if after this rest, at least one of: the detachment parameter has not attained a nominal detachment threshold in a first movement time; an attachment index corresponding to a particular shape of a measurement signal of the wheel unit has been detected under specific evaluation conditions, occurs.
