Abstract: Tire pressure control devices include first sensors to deliver repeatedly a measured value M1 for the rotation speed of the wheel. A measurand, from which the rotation speed of the associated wheel can be derived, is detected in a pointwise manner by means of a second sensor over a predetermined rotation angle ? of the wheel as a function of time, is subjected to a low pass filtering in a subsequent first time interval ?t1 and from the filtered development of the measurand a second measured value M2 is determined, which is a measurement for the rotation speed or respectively for the angular speed of the associated wheel. Each tire pressure control device transmits at the end of a second time interval ?t2 the second measured value M2 together with an identification of the tire pressure control device to a central unit. Comparing M1 and M2 determines wheel position.

Abstract: A method for operating a tire pressure monitoring unit for monitoring pneumatic tires of a vehicle includes where a pressure measurement is taken at regular intervals using a pressure sensor and the pressure information is transmitted wirelessly at larger intervals by a transmitter. A control unit checks whether a pressure change exceeding a threshold value has occurred, and, if so, pressure measurements are taken at shortened intervals and the transmission activity is increased. The control unit uses a first threshold value for the pressure change in the case of a stationary vehicle and uses a second threshold value, which differs from the first threshold value, for the pressure change in the case of a moving vehicle. The control unit, by evaluating a signal of an acceleration sensor of the tire pressure monitoring unit, establishes whether the first threshold value or the second threshold value is used.

An evaluation device receives the transmitted identifier and compares the information on the rotation speed of the wheel transmitted along with the identifier, with rotation speed information, which were acquired by the ABS sensors for the same time span and transferred to the evaluation device.

The server may modify the search request to increase the likelihood that the search request will return relevant results. The identified list of resources is then provided back to the client device, along with the modified search request if applicable, which then originates and transmits the search request to each of the identified resources or subset thereof.
