A tyre sensor device having a container with a container housing and a tyre sensor device electronics assembly, the tyre sensor device electronics assembly including a foldable flexible printed circuit board with at least two printed circuit board portions each having two surfaces and being suitable for placement of electronic components of the tyre sensor device. The electronic components have at least one sensor for sensing at least one tyre parameter. The foldable flexible printed circuit board is configured to be folded for insertion of the tyre sensor device electronics assembly in the container housing. The container housing is adapted to contain the foldable printed circuit board in a folded condition.

A tire air pressure detection system and a vehicle body side device to detect air pressure of a plurality of tires. The vehicle body side device causes a transmission unit to transmit to all tire side devices, a transmission stop signal instructing transition to a transmission stop state and then the transmission unit transmits a transmission standby signal at a transmission strength that enables the signal to reach the tire side devices; and then the transmission unit transmits to the one of the tire side devices, a transmission request signal requesting a transmission of a signal including a unique identifier stored in that tire side device; and when it is determined that a reception unit has received a response signal in response to the transmission request signal, the transmission unit transmits a transmission standby signal and a transmission request signal to the tire side device corresponding to the next tire.

Method and apparatus are disclosed for controlling vehicle TPMS sensor localization. An example vehicle includes a plurality of tire pressure monitoring system (TPMS) sensors, a communication module, and a controller. The controller is to detect an initiation event associated with the vehicle, and, in response to detecting the initiation event, determine whether first localization information is valid based on information associated with the TPMS sensors. The controller is also to initiate, via the communication module, a localization procedure at the TPMS sensors when the first localization information is not valid.

Embodiments provide a tire pressure measurement device that includes an electromechanical transducer configured to convert mechanical energy from tire deformation of a tire into electrical energy for powering the tire pressure measurement device; and an energy harvesting circuit configured to receive and store the electrical energy from the electromechanical transducer, where the energy harvesting circuit is further configured to supply the stored electrical energy to the tire pressure measurement device.

A portable tire pressure monitoring system (TPMS) tool includes a tire sensor trigger device ensuring the TPMS tool is in close proximity to a TPMS tire sensor to trigger or awaken the sensor to emit measured tire data. In one example, a manually displaceable trigger signal contact device in the form of a push button is used. On manual displacement of the push button against the tire, the tool generates the tire sensor trigger signal. In another example, the tool includes a first power source in the form of a high density capacitor. In another example, a second power source in the form of a lithium button-type battery is used to selectively provide power or recharge the first power source between function cycles.

A tire condition detecting device includes a controlling section that determines whether there is an anomaly in the tire based on the condition of the tire detected by the condition detecting section. A protocol that is designated by a trigger device is defined as a first protocol, and protocols that are not designated by the trigger device are defined as second protocols. When determining that there is no anomaly in the tire, the controlling section causes the transmission section to transmit only the data signals using the first protocol. When determining that there is an anomaly in the tire, the controlling section causes the transmission section to transmit the data signals using the second protocols in addition to the data signals using the first protocol.

A monitoring device comprises an acquisition unit configured to acquire information related to movement or stoppage of the vehicle; a request signal transmission unit configured to wirelessly transmit the request signal to the detection device if it is determined that the vehicle is stopped based on the information acquired by the acquisition unit; an air pressure signal reception unit configured to receive the air pressure signal that is transmitted from the detection device in response to the request signal; and an output unit configured to, in a case where the request signal transmission unit transmitted the request signal, outputs a warning signal for giving a warning inside the vehicle, if the air pressure signal in response to the request signal is not received by the air pressure signal reception unit.

A method for operating a monitoring device for at least one vehicle parameter, in particular an air-pressure sensor for the tire-pressure vehicle parameter. The monitoring device is operated in a drive mode or in a stationary mode as a function of the velocity of the vehicle. Connection signals for the wireless connection to an external device, in particular a configuration device for the monitoring device, are transmitted in the stationary mode. Prior to the change to the stationary mode, the monitoring device is operated in a first intermediate mode. A passive search for wireless connection signals from the external device is carried out in the first intermediate mode.
