Description

Monitoring system for pneumatic vehicles and device for

Transmitting data of a vehicle tire to a receiver

The invention relates to a monitoring system for pneumatic vehicles and a device for transmitting data of a vehicle tire to a receiver. This invention is suitable for pneumatic vehicles, especially for motor vehicles, in which the vehicle tires are equipped with sensors that provide the physical data, such as the air pressure of the

Vehicle tires, measure.

State of the art

Modern vehicle tires consist of a treadmill and a carcass. The treadmill itself includes a tread (profile), which is responsible for sufficient road grip, as well as water or snow displacement. The carcass includes inter alia cords, which specify the shape of the vehicle tire accordingly. The inner layer ensures that the vehicle tire is airtight. The side panels protect against side damage and the core profile favors the driving stability as well as the steering and comfort behavior. The provided steel cores together with the bead reinforcements ensure the correct seat on the rim and support the driving stability and the precise steering behavior.

Devices are known from the prior art, the physical sizes of the vehicle tires, such as the tire pressure on a

Display means in the cockpit of a vehicle, transmit. Especially at

Large tires it is known that so-called TPMS systems (Tire Pressure Monitoring System) it provide, on the outside of the vehicle tire valve a

To install measuring device, which is used to monitor the tire pressure. At this time, the pressure of the air existing inside the tire is measured on the valve.

Alternatively, such systems can be attached to the rim of the vehicle tire. It is also known that such systems measure the temperature. The data itself are transmitted via GSM, GPS, Bluetooth or radio or comparable transmission methods to a receiver module within the vehicle and preferably displayed visually in the area of the cockpit at least. It is distinguished by the receiver from which tire the corresponding signal received, so that the user is informed exactly about a possible defect. From DE 10 2007 01 1 678 it is already known, data of a

Monitoring system of a motor vehicle component with a

Communication module of the motor vehicle to exchange to certain

To make states of the vehicle component to the driver visually present. Also mentioned herein is a tire control pressure system in which all tires of the motor vehicle are provided with sensors which control the pressure inside the vehicle

Determine vehicle tire while driving and transmit wirelessly using a transmitter as a communication module. This data can then be retrieved by the vehicle user in the communication module and displayed on a display.

Also known from DE 198 568 98 A1 is an arrangement which is used for transmitting signals which generates data in a device for monitoring the tire pressure on vehicle wheels and transmits them to an evaluation unit and receiver unit. A module equipped with the receiver unit displays the current status to the user in the event of a corresponding warning state. It is also known that lack of vehicle tires include frequent breakdown and accident causes, with a lower cause of tire damage

Tire pressure is determined. It is also known that the low tire pressure leads to high fuel consumption and thus to high CO 2 emissions, so that the knowledge has been gained that the correct tire pressure enables an efficient as well as safe driving with a vehicle. To remedy this situation, tire control systems (Tire Pressure Monitoring System) are commercially available, with which it is possible to use several electronic tire pressure sensors, evaluate their signals and display the result on a display unit accordingly. In particular, for use in large tires (for buses, trucks and the like) such a device is known.

Disadvantages of the prior art

From the prior art, a variety of systems are known which measure the physical data of vehicle tires, such as tire pressure, but also temperature and thus check. These are each individual solutions that are only partially or not compatible with each other.

When changing tires it is necessary to adjust the systems accordingly

match, renew or at least the sensors in the new

Vehicle tires are arranged to train on the system that exists in the vehicle. This means a considerable effort and is associated with additional costs, since such an adaptive adaptation of the vehicle driver can not be carried out by himself, since special tools, such as

For example, control and read-out systems are necessary, which, however, only the expert trade has alone because of their costs. The sensors for detecting the physical data consist of a housing with an electronics located therein. These sensors are commonly used in Tire inside arranged in the immediate region of the tire valve of the vehicle tire.

Alternatively, it can also be provided that at least one transmitting unit outside the interior of the vehicle tire, for example in the region of

Valve is preferably arranged on the valve mouth. The sensors that measure the pressure are usually located inside the tire. They are held there with a looped around the rim fastening tape or arranged directly by gluing on the tire inner wall.

The sensors send corresponding signals to receiver modules, which are also arranged in the tire area. However, these can either not be removed at all or only with the help of special tools. The time required in this regard is very large, such recipient or

Remove, replace and rearrange transmitter units.

Object of the invention

The problem of the invention is a monitoring system

to provide, which is also interchangeable and reusable in a very simple manner without the aid of special tools or electronic special devices.

Solution of the task

The solution of the problem is provided by the features of claim 1.

Advantages of the invention

The basic idea of the invention is to provide a monitoring system in which the corresponding sensors for measuring the

physical data, such as pressure and / or temperature within the vehicle tire is arranged. These sensors send signals to

Receiver / transmitter module, which is arranged outside the interior of the vehicle tire, preferably on the vehicle tire itself. This receiver / transmitter module has the characteristics of being very small in size and removable from the tire by simple commercial means.

Furthermore, it has the property of communicating with a receiver module within the vehicle so that the data transmitted from the tire interior can be transmitted via the receiver / transmitter module to a receiver module, so that at least in the critical area in which the safety of the vehicle is no longer present, the vehicle driver signals a corresponding warning signal.

An essential advantage of the invention is that the receiver / transmitter module is designed universally. This means that this has properties that this is not only within or outside the vehicle tire can be arranged, but provides opportunities to adaptively fix them at almost any point. To provide this feature, a universal housing is provided in which the necessary electronics for receiving the

corresponding data, but also to send the data with a

Power supply unit is arranged. In addition, the universal housing has an adapter area, which has the property of being attachable to different fastening systems. This in turn has the advantage that this receiver / transmitter module is not only suitable for vehicles, but also for other facilities, such as ships or aircraft or any other devices. It serves to wirelessly receive the provided with a low transmission power sensors or their physical data, prepare such that they can then be sent to a receiver module for further processing, such as display on a display. The adapter area is part of the universal housing. The adapter region advantageously has a bore which is suitable, for example, for receiving at least part of a vehicle valve. However, if this area is designed to be too short in relation to the length, it is provided to provide an adapter in the adapter element, which is screwed onto a vehicle valve. After screwing the adapter element onto the vehicle valve, the receiver / transmitter module can be mounted with its universal housing. It is designed such that this plan is arranged within the vehicle rim and thus does not form a protruding element in the region of the vehicle tire.

If a driving is changed, it is sufficient to easily remove the receiver / transmitter module (without any tools possible), in order to use this for the spare tire or for other facilities. It has the property that this with defined sensors, which in the

the immediate area of the receiver / transmitter module are arranged, automatically establishes the communication and the data to a central unit in the

Training a receiver module sent on.

The respective receiver / transmitter modules can advantageously be integrated into a network, so that bidirectional communication is also conceivable.

Another embodiment of the invention is in the use of

Universal housing with the receiver / transmitter module can be seen in the fact that other parameters can be detected and monitored on a motor vehicle both in the mobile and in the stationary training. Data, such as temperature, current position pressure, humidity level,

Pressure tightness, tire tread depth and similar parameters can be determined by the

Receive / transmit modules receive advantageously evaluated and further transmitted.
