Method, system, and system components for wireless tire pressure monitoring
Disclosed is a method for monitoring and wirelessly signaling data that contains information on the pressure states prevailing in tires of wheels of a vehicle. In the method, electronic modules that are arranged in the wheels wirelessly transmit the data to control device which is arranged in the vehicle. No data is transmitted during a first mode associated with a standstill state of the vehicle, while the respective electronic module transmits the data to the control device in the form of telegrams, during at least one other mode associated with another state of the vehicle. The respective electronic module at least temporarily transmits n telegrams containing the data per time unit to the control device, n being a function of time.
1. A method for monitoring and wirelessly signaling data containing information about a pressure condition 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,
wherein the data is transmitted in a form of datagrams by a respective electronic module to the controller during a second mode associated with a starting state of the vehicle,
wherein the data is transmitted in the form of datagrams by the respective electronic module to the controller during a third mode associated with a driving state of the vehicle,
wherein the datagrams containing the data are transmitted per n unit of time to the controller by the respective electronic module intermittently with n being a function of time,
wherein the third mode of the driving state comprises a lower transmission rate as compared to the second mode of the starting state.
2. The method according to claim 1 , wherein the data is transmitted during a fourth mode with an even lower transmission rate as compared to the third mode, the fourth mode being associated with a second driving state of the vehicle.
3. The method according to claim 2 , wherein the fourth mode begins approximately 15 minutes after starting to drive.
4. A method for monitoring and wirelessly signaling data that contains information on a pressure in tires of wheels of a vehicle, wherein the data are transmitted wirelessly in a form of telegrams by electronic modules disposed in the wheels to a control device disposed in the vehicle, the electronic modules being switched by an acceleration sensor from a first mode which is assigned to a standstill state of the vehicle to a starting mode which is assigned to a starting-off state of the vehicle, the electronic modules send in the starting mode telegrams which contain information on a direction of rotation or an identification and which are shortened by containing no information on a temperature in the wheel.
5. A method for monitoring and wirelessly signaling data that contain information on a pressure in tires of wheels of a vehicle, wherein the data are transmitted wirelessly in a form of telegrams by electronic modules disposed in the wheels to a control device disposed in the vehicle, the electronic modules being switched by an acceleration sensor from a first mode which is assigned to a standstill state of the vehicle to a starting mode which is assigned to a starting-off state of the vehicle, the electronic modules send in the starting mode telegrams which contain information on a direction of rotation or an identification and which are shortened by containing no information on the pressure in the wheel.
