Description

The invention relates to a method for receiving tire data with a stationary measuring station.

It is known to use tire pressure monitoring on vehicle tires to reliably detect pressure loss.

There are various tire pressure monitoring systems on the market, each of which communicates with an external receiving system in different ways. Fleet operators want to be able to receive tire data from all their vehicles, even if individual vehicles are equipped with different types of tire modules.

The object of the invention was to provide a method by which the reception of tire data with a stationary measuring station is significantly improved.

2. b) Identifizieren des Fahrzeuges mit einer Identifiziervorrichtung,
3. c) Ermitteln von Fahrzeug-Informationen zu dem identifizierten Fahrzeug mit einer Datenbank,

wobei die Fahrzeug-Informationen Daten zu dem am Fahrzeug eingesetzten Reifenmodulen umfassen,
wobei mit den Daten ein bestimmter Typ von unterschiedlichen Reifenmodulen ermittelt werden kann,

• d) Initiieren von Sendesignalen mit der stationären Messstation,

wobei die Sendesignale auf den jeweiligen Typ des eingesetzten Reifenmoduls abgestimmt sind,

• e) Empfangen der Sendesignale durch das Reifenmodul am Fahrzeugreifen,
• f) Senden eines Antwortsignals durch das Reifenmodul mit Reifendaten,
• g) Empfangen des Antwortsignal mit der stationären Messeinheit,

wobei die stationäre Messeinheit Antwortsignale von unterschiedlichen Typen von Reifenmodulen empfangen und auswerten kann,

• h) Auswerten des Antwortsignales von dem Reifenmodul und Weiterleiten der ausgewerteten Daten.

The task is solved using a procedure with the following steps:

1. a) Providing a vehicle with at least one vehicle tyre with a tyre module,
2. b) Identifying the vehicle with an identification device,
3. c) Determining vehicle information about the identified vehicle using a database,

where the vehicle information includes data on the tire modules used on the vehicle,
where the data can be used to determine a specific type of different tire modules,

• d) Initiating transmission signals with the stationary measuring station,

The transmission signals are tailored to the respective type of tire module used,

• e) Receiving the transmission signals by the tire module on the vehicle tire,
• f) Sending a response signal by the tire module with tire data,
• g) Receiving the response signal with the stationary measuring unit,

whereby the stationary measuring unit can receive and evaluate response signals from different types of tire modules,

• h) Evaluating the response signal from the tire module and forwarding the evaluated data.

A particular advantage of the invention is that the new method significantly improves the reception of tire data with a stationary measuring station. With the new method, it is now possible for the stationary measuring station to also query and record tire data from different types of tire modules. The stationary measuring unit is now capable of receiving tire data from different tire modules, which in particular use different transmission protocols. For example, the tractor unit of a commercial vehicle could be equipped with different tire modules than the truck trailer. The new method ensures that both types of tire modules can be read with the stationary measuring unit.

In an advantageous development of the invention, the tire data transmitted by the tire module includes a tire pressure measured on the vehicle tire. The current tire pressure measured on the vehicle tire is particularly important for tire maintenance.

In a further advantageous development of the invention, it is provided that the identification device comprises a transponder reader at the stationary measuring station,
A transponder containing information about the vehicle is arranged on the vehicle.

A transponder reader can be easily installed at the stationary measuring station. The reader allows all vehicle information to be recorded quickly and easily.

In a further advantageous development of the invention, the identification device at the stationary measuring station comprises a camera for recognizing the license plate on the vehicle, whereby the license plate is used to identify the vehicle. The stationary measuring station can be easily equipped with a camera.

In a further advantageous development of the invention, the stationary transmission unit transmits different transmission signals one after the other if the vehicle and/or the trailer on the vehicle are equipped with different types of tire modules. This ensures that all tire modules arranged on the vehicle are read one after the other.

In a further advantageous development of the invention, the tire data from the tire module includes a measured temperature, a measured tire load, and/or a determined tread depth of the vehicle tire. This tire data is particularly important for vehicle tire maintenance.

A further advantageous development of the invention provides for the tire data to be forwarded to an online database. This allows the tire data to be easily stored in a central location. Furthermore, the data can be easily forwarded to a fleet operator.

In a further advantageous development of the invention, the tire data is transmitted from the stationary measuring station to the database via a radio connection. This makes the measurement data available to the database very quickly.

In a further advantageous development of the invention, the vehicle is a commercial vehicle or a commercial vehicle trailer. The measuring system is particularly suitable for use in commercial vehicles.

The invention is described in more detail below using an exemplary embodiment.

• 1: Eine Nutzfahrzeugzugmaschine in der Seitenansicht.

It shows:

• 1 : A commercial vehicle tractor in side view.

The 1 shows an exemplary embodiment. It depicts a side view of a tractor of a commercial vehicle. The tractor comprises a plurality of vehicle tires, each equipped with a tire module 2. The tire modules 2 are attached, for example, to the inside of the tire and include, among other things, a pressure sensor, a temperature sensor, and an acceleration sensor.

After vehicle 5 has approached stationary measuring station 3, the vehicle is first identified. At stationary measuring station 3, for example, a camera is mounted that can identify the vehicle's license plate. Subsequently, the tire modules mounted on the vehicle are identified via a query against a database. By identifying the tire modules, it is determined which transmission signal is required to initiate transmission of the respective tire modules. The stationary measuring station then transmits the transmission signal specific to the tire module. The tire modules receive the transmission signal and subsequently send a response signal with the current tire data to the stationary measuring unit.

If the vehicle is equipped with different tire modules, a second transmission signal is initiated to also record the tire data from the second tire module type. A special feature of the stationary measuring station is that it can also receive and evaluate response signals from different types of tire modules. Measuring station 3 also receives the transmission signals from those tire modules that spontaneously transmit the tire data without initiation by the measuring station.

The tire data received from the stationary measuring station is transmitted wirelessly to an online database. If, for example, one of the vehicle's tires is under-inflated, an alert is generated, which can be forwarded to a fleet operator.
