A tire module and cover for attachment to a pneumatic tire for vehicles is disclosed. The tire module has a device for measuring and/or monitoring the air pressure in the tire, a transmitter, a mechanical-electrical transducer, and an accumulator for electrical energy storage. The cover includes a flange which extends outwardly away from the tire module and has an underside for attachment to the inner side of the tire, said flange forming the edge of the interior space of the cover. The inner height of the cover may be less than or equal to the height of the tire module measured from the underside to the top side thereof. The flange has an inwardly directed projection which engages beneath the tire module. The underside of the tire module is higher up in the region of the flange projection as compared to a central underside region.

Tire module with piezoelectric transducer

A tire pressure monitoring device is mounted on a wheel of a vehicle provided with a pneumatic tire. The device contains a tire pressure sensor and a transmitter which transmits signals wirelessly in transmission intervals, between which in each case there is a first transmission pause. A control device controls the sensor, the transmitter and the first transmission pause thereof. A source provides electrical energy to a rechargeable electric accumulator, in which electrical energy delivered from the source is stored until it is required. The state of charge of the rechargeable electric accumulator is monitored by a monitoring device and one or more of the first transmission causes is/are then ended as soon as enough electrical energy is stored in the rechargeable accumulator to operate the tire pressure monitoring device between two successive first transmission pauses until the conclusion of a predetermined number of transmission processes.

Method and device for operating a tire pressure monitoring device

A tire module for attachment to an inside of a pneumatic tire for vehicles includes a device for measuring and/or monitoring the air pressure in the tire. A transmitter for transmitting radio signals, which contains information regarding the air pressure in the tire, includes a mechanical-electrical transducer having a flexible piezo-electrical element, which converts alternating changes in shape of the piezo-electric element caused by the rolling tire into electric energy and includes a storage unit for the electric energy, which is connected to the transducer. The transducer may contain a circular, disc-like, piezo-electric element, which in the following is described as piezo disc and on which an electrical voltage generated through the piezo effect is tapped off on contact points which are located on opposite sides of the piezo disc.

Tire module with piezo-electric transducer and tire equipped therewith

A tire pressure sensor for motor vehicles includes a housing accommodating an integrated circuit (sensor IC), wherein the sensor IC has a microcontroller and a pressure sensor. The microcontroller, transfers pressure measurement values acquired by the pressure sensor to a receiver by wireless communication. The sensor IC has an internal memory, in which executable instructions and data can be stored, which, when executed, result in the acquisition and transference of the pressure measurement data. The sensor IC is coupled to an auxiliary memory module disposed in the housing. Numerous different data packets, with respective instructions or data, are stored in the memory module which can be activated via the microcontroller, in order to copy a selected data packet into the internal memory. The microcontroller controls the power supply for the auxiliary memory module such that the auxiliary memory can be switched over to an energy saving mode.

A tire pressure monitoring device is equipped for attaching to a wheel of a vehicle provided with pneumatic tires. The device measures the tire air pressure present in the pneumatic tire or a change of the tire pressure. An electrical circuit controls the tire pressure monitoring device. A memory stores a program for the electrical circuit. A first transmitter operates in a first frequency range for transmitting data out of the tire pressure monitoring device to a first receiver located outside the tire pressure monitoring device. In the memory initially a basic version of the program is stored, out of which multiple different versions of the program for multiple vehicle types can be developed. Subsequently, a fitting full version for a selected vehicle type is created in that program parameters intended for the selected vehicle type are subsequently stored in the memory of the tire pressure monitoring device.
