vehicle tires

Abstract

It is proposed that the vehicle tire has a sensor for detecting environmental conditions and / or tire information, wherein the sensor is a passive Bluetooth sensor (2), in which the sensor draws its energy for transmitting information from existing radiation in its environment, wherein the sensor is arranged with a label (4) on a surface on the vehicle tire (1).

Description

The invention relates to a vehicle tire.Vehicle tires are stored in storage halls for a certain time after manufacture. If the vehicle tires are stored for too long a time or if the vehicle tires are stored at too high temperatures, the quality of the vehicle tires may be impaired.The invention is based on the object of providing a vehicle tire in which monitoring of stored vehicle tires is made possible with simple means.The object is achieved according to the preamble and the characterizing features of claim 1 in that the vehicle tire comprises a sensor for detecting environmental conditions and / or tire information, wherein the sensor is a passive Bluetooth sensor, wherein the sensor obtains its energy for transmitting information from an existing radiation in its environment, wherein the sensor is arranged with a label on a surface on the vehicle tire.An advantage of the invention is to be seen in particular in the fact that the storage of vehicle tires can be easily controlled and monitored using a Bluetooth sensor.The use of a passive Bluetooth sensor has the advantage that it does not require a battery for an energy supply, in particular. The Bluetooth sensor receives an existing ambient radiation, in particular a radio frequency radiation or radiation from a W-Lan router, and uses this radiation energy to forward information from the Bluetooth sensor, the storage temperature of the vehicle tire, to a receiver.The Bluetooth sensor does not require its own energy supply and thus has a very compact construction.The sensor information is transmitted to a receiver located outside the vehicle tire via a Bluetooth connection.The Bluetooth sensor is characterized by a low weight and a compact construction, whereby it can be easily arranged on a label. The Bluetooth sensor can be integrated, for example, on the rear side of the label. It comprises, inter alia, a temperature sensor with which the ambient temperature can be measured. If the temperature exceeds a certain threshold value, a warning message is generated, which is forwarded to a receiver.In an advantageous development of the invention, it is provided that the sensor is used for monitoring vehicle tires in a store.With the Bluetooth sensor, certain vehicle tires can be easily located in the store. An employee of the warehouse can be informed in this way of where a specific vehicle tire is located in the warehouse.In a further advantageous development of the invention, it is provided that the ambient conditions detected by the sensor comprise the storage temperature and / or the storage humidity of the vehicle tire in a storage.Monitoring these environmental conditions is particularly important to ensure high quality for the vehicle tires.In a further advantageous development of the invention, it is provided that the tire information recorded by the sensor comprises a tire identification code and / or the location of the vehicle tire.The tire identification code can be used to determine in a simple manner what tire type the stored tire is.In a further advantageous development of the invention, it is provided that the label comprises an energy label and is adhesively bonded to the tread or to the side wall.In certain countries, it is prescribed to provide the vehicle tires with such an energy label before sale, which label comprises, for example, a classification of the rolling resistance.In a further advantageous development of the invention, it is provided that the vehicle tire is packed into a plastic film, wherein the label is arranged on an upper side of the plastic film.The plastic film serves to protect the stored or transported tires from dirt or dust. To identify the vehicle tires, the wrapped vehicle tires are likewise provided with labels. On the rear side of these labels, corresponding Bluetooth sensors can be integrated in a simple manner.In a further advantageous development of the invention, it is provided that the sensor has dimensions in the form of a flat stamp, wherein the width and height dimensions are between 10 and 30 mm.As a result, the sensor can be integrated on a label in a simple manner. The sensor is also characterized by a low weight.The invention will be explained in more detail on the basis of an exemplary embodiment. It shows: FIG. 1 : shows a vehicle tire with a passive Bluetooth sensorFIG. 1 shows an exemplary embodiment. The vehicle tire 1 is shown in a radial sectional view.The passive Bluetooth sensor 2 is arranged, for example, on the back side of the label 4. The Bluetooth sensor 2 is designed in the form of a flat letter mark. The Bluetooth sensor does not have its own power supply. In particular, it receives radio frequency radiation from its environment and uses the energy of the radiation to transmit information to a receiver which is arranged outside the vehicle tire. The receiver may be disposed at a central position in a tire bearing. The data are transmitted via a Bluetooth connection. This also makes it possible to query the data of the Bluetooth sensor using a smartphone.It is also possible for the smartphone to access a cloud database via an Internet connection in order to query measurement data from the Bluetooth sensor. The measurement data can be transmitted to the cloud database in advance using another receiving device.The label 4 can be, for example, an energy label which is bonded to the surface of the tread 3 as standard. The energy label in particular indirectly indicates the relative rolling resistance of the vehicle tire. In addition, the relative noise emission is indicated with respect to other vehicle tires. The energy label is directed in particular to the end customer. The Bluetooth sensor incorporates various sensors which can measure, for example, the ambient temperature or the ambient humidity. The vehicle tires stored in a store are each provided with a Bluetooth sensor and can transmit the measured data to a receiver. The receiver is arranged, for example, at a central position in a tire bearing. If a certain threshold value is exceeded, for example a maximum temperature, then a warning message is generated. The warning message can contain, for example, information that the vehicle tire is stored at too high a temperature. In addition, a tire identification code, for example, is stored in the memory of the Bluetooth sensor. The tire identification code can be used, for example, to determine the date of manufacture of the vehicle tire in a simple manner.List of reference characters1 Vehicle tire 2 Bluetooth sensor 3 Tread 4 Label with energy label 5 Sidewall
