  • Patent number: 11659306
    Abstract: A method for communication of a plurality of wheel units with one another and with a device for remotely monitoring and/or controlling the wheel units, the wheel units measuring a pressure value of a wheel of a motor vehicle as parameter(s). The units are identified beforehand and each wheel unit may identify the other wheel units, the communication taking place in accordance with a communication standard allowing a bidirectional data exchange. A hub wheel unit storing the pressure values measured by each of the wheel units is selected at least temporarily, the other units being peripheral. The hub unit sends a signaling frame in the direction of the peripheral units, received in a peripheral unit through scanning. The pressure values are communicated between the wheel units and a device solely via the hub unit.

  • Patent number: 11440359
    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.

  • Publication number: 20220150709
    Abstract: A method for adjusting a periodicity of communication between a wheel unit and a remote monitoring and/or control device, a communication being carried out using ultra-high-frequency radio waves, the wheel unit sending with a predetermined first periodicity basic signaling messages indicating its presence to any communication device located in an environment of the wheel unit. The wheel unit, having previously stored a group of communication devices authorized to serve as monitoring devices therefor, checks whether the communication device having sent a response message belongs to the group, and, if this is the case, the wheel unit replaces the first periodicity with at least one shorter second periodicity resulting in a more intense two-way exchange for any signaling message subsequently sent from the wheel unit to the authorized device.

  • Publication number: 20220134817
    Abstract: A method for controlling, by a remote monitoring and/or control device, an activation of a command in a wheel unit that has previously stored a group of authorized UHF communication devices and checked whether a device that has sent a response message belongs to the group. If it does, the wheel unit sends a series of command-related signaling messages with each message associated with a single command. When the authorized device receives a message relating to a specific command that the authorized device requests to have activated by the wheel unit, the authorized device sends back to the wheel unit a standard response message interpreted as an activation order for the wheel unit to activate the specific command.

  • Patent number: 11110757
    Abstract: A method for locating at least one wheel of a vehicle, the wheels each being equipped with an electronic device which sends a wheel rotation signal to a central unit, a speed sensor for each wheel which supplies a signal to the central unit. For each electronic device, at least two sequences of several acquisitions are performed by formation of the signal with simultaneous acquisition by the central unit of the signal transmitted by each speed sensor. A pairing is performed of the two signals for an electronic device with each of the wheel speed signals. For each pair, a phase offset is measured between the two signals. When a constant phase offset is measured in the pairs with a speed sensor, the electronic device associated with the signal is identified as being assigned to the wheel associated with the speed sensor.
