Method, system and system components for wireless tire pressure monitoring
First Claim
1. A method for monitoring and wirelessly signaling data containing information about the pressure conditions present in pneumatic tires of wheels of a vehicle, the data being transmitted wirelessly by electronic modules disposed in the wheels to a controller disposed in the vehicle, wherein a first mode is associated with a stopped state of the vehicle, and data being transmitted in the form of datagrams by the respective electronic module to the controller during at least one further mode which is associated with a different state of the vehicle, characterized in that least intermittently a plurality of datagrams containing the same data are consecutively transmitted in an accumulated manner to the controller by the respective electronic module, wherein the data is transmitted in the form of a first datagram during a second mode, which is associated with a driving state of the vehicle, and that data is transmitted only partially in the form of a second datagram, which is shorter than the first datagram, during a third mode, which is associated with a starting state of the vehicle.

Abstract
In order to monitor and wirelessly signal data (D, D*) containing information (DRK) about the pressure conditions present in pneumatic tires of wheels of a vehicle, it is proposed to transmit the data from electronic modules (wheel electronics) disposed in the wheels wirelessly to a controller disposed in the vehicle, wherein no data is transmitted during a stopped mode of the vehicle, and wherein the data (D*) is transmitted in the form of datagrams (DT*) during at least one further mode, which is preferably associated with a starting mode of the vehicle, in that at least intermittently a plurality of, preferably shortened, datagrams (DT*) containing the same data (D*) are consecutively transmitted in a cumulative manner to the controller. In this way, the required data (D*) is transmitted only intermittently, however in a lumped form, to the controller, whereby the transmission duration, but not the actual usage duration, is shortened, and additionally battery energy is saved, without any data loss occurring.

13. A system for monitoring and wirelessly signaling data containing information about the pressure conditions presents in pneumatic tires of wheels of a vehicle, the system comprising:
-
a controller disposed in the vehicle; and electronic modules, disposed in the wheels, for wirelessly transmitting the data to the controller, wherein a first mode is associated with a stopped state of the vehicle, and data being transmitted in the form of a first datagram by the respective electronic module to the controller during a second mode which is associated with a driving state of the vehicle, the modules being further configured for, least intermittently, consecutively transmitting a plurality of datagrams containing the same data in an accumulated manner to the controller by respective electronic modules, and wherein data is transmitted only partially in the form of a second datagram, which is shorter than the first datagram, during a third mode, which is associated with a starting state of the vehicle wherein the data in the second datagram contains at least no information about the pressure condition present in the respective wheel and/or about the temperature present in the respective wheel. - View Dependent Claims (14)

15. A pressure sensor system for monitoring and wirelessly signaling the pressure state of a pneumatic tire of a vehicle, comprising:
-
a controller disposed in the vehicle; and an electronic module placed within the pneumatic tire of the vehicle, the electronic module comprising a pressure sensor, a transmitter and a motion sensor; wherein the controller is configured to receive data from the electronic module sent by the transmitter; wherein the electronic module is configured to transmit to the controller during a driving state a first datagram comprising a pressure state of the pneumatic tire; wherein the electronic module is configured to transmit to the controller during a starting state a second datagram comprising an identification state without the pressure state of the pneumatic tire; wherein the second datagram is shorter in length as compared to the first datagram.
