A tire pressure monitoring unit includes a pressure sensor, a temperature sensor, a transmitter for wireless transmission of pressure and temperature data HF signals, a receiver for receiving wireless control LF signals, a microcontroller containing a program memory and a data storage device containing a library of control programs to control the measurement and transmission activity of the tire pressure monitoring unit. The microcontroller selects from this library, on the basis of control signals that are received, a control program and then writing it into its program memory. When a loading program is activated by a control signal, it causes the microcontroller to transfer into the data storage device an additional control program that is received by the receiver. A method includes adding, to a library of control programs in a data storage device connected to a microcontroller of a tire pressure monitoring unit, an additional control program.

Tire pressure monitoring unit with expandable program library and method for supplementing a program library of a tire pressure monitoring unit

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

Tire pressure control devices include first sensors to deliver repeatedly a measured value Mfor 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 &#x3c6; of the wheel as a function of time, is subjected to a low pass filtering in a subsequent first time interval &#x394;tand from the filtered development of the measurand a second measured value Mis 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 &#x394;tthe second measured value Mtogether with an identification of the tire pressure control device to a central unit. Comparing Mand Mdetermines wheel position.

Method of associating tire pressure control apparatuses to wheel positions

Allocates identifiers of units of a tire pressure monitoring system to the positions of ABS-sensors which are each assigned to the wheels of the vehicle. The identifiers are contained in signals that are emitted by the units. Each unit, which is called a wheel electronic, has a pressure sensor, which is sensitive to the tire pressure of the wheel, a motion sensor, which provides information on the rotation speed of the wheel, a memory with the individual identifier of the wheel stored therein, and a transmitter, which transmits signals only containing information on the rotation speed of the respective wheel, to a receiver. 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.

Method for allocating identification codes which are contained in signals transmitted by components of a tire pressure monitoring system, said components being attached to wheels of the vehicle, to the wheel positions. A plurality of sensors to the tire pressure, to the rolling direction of the wheel, to the shocks, as well as a memory for the identification code, and a transmitter which supplies signals with the identification code, the rolling direction and the occurrence of a shock on a wheel to a receiver which, based on the supplied rolling direction information, distinguishes identification codes pertaining to wheels on the left-hand or right-hand side of the vehicle from shocks which occur on the left-hand or right-hand side of the vehicle, measures the time interval elapsing between shock signals on one side of the vehicle, multiplies this time interval by the velocity of the vehicle measured within the same time interval.

The invention describes a method for allocating identifiers of wheel electronics of a tire pressure monitoring system to positions of wheels of a vehicle, the simultaneously occurring rotation speeds of the wheels, normalized on a consistently chosen rolling radius of the wheels differ during cornering because of the different positions of the wheels on the vehicle, so that the positions of the wheels can be sorted according to increasing speed of the wheels during cornering, the wheel electronics of each wheel comprising a pressure sensor, a motion sensor, a memory and a transmitter, which transmits signals to a receiver being connected to an evaluation device, which receives the transmitted identifiers and compares the distances which the corresponding wheels have traveled in a defined time span, sorts the identifiers according to the length of the distance traveled in the defined time span and allocates the identifiers to the wheel positions.
