Abstract

A tire side controller (2) includes a tire pressure sensor (3), a memory (4), a radio transmitter (5) and a programming receiver (6). The memory stores several codes associated with transmission formats specifying e.g. tire type. The radio transmitter communicates with the radio receiver (8) of a vehicle side controller (20) to transmit the tire pressure data to the same controller. An acknowledgement signal is transferred between the programming receiver and programming transmitter (9) on the vehicle side controller to select one of the codes and/or transmission formats.

Description

  • The The invention relates to a tire pressure monitoring system with at least a monitoring device, which is integrated into a tire that detects the tire pressure and over transmits a radio interface to a central unit arranged in the vehicle. This central unit evaluates the received radio signals. The determined tire pressures or a drastic change the tire pressure is output to the driver.
  • Such a system is out of the DE 199 24 830 A1 and from the DE 10 2004 052 051 A1 known. The DE 10 2004 052 051 A1 was used to form the preamble of valid claim 1. The universal monitoring device in the tire is provided with a memory unit for storing a plurality of codes, each code of which comprises a transmission format that is specific to a manufacturer and / or tire type. With the help of a programming transmitter, a specific code and thus a specific transmission format can be selected; This is then used in the following exclusively for the transmission of the information regarding the tire pressure from the universal monitoring device to the central device in the vehicle with the associated control unit and the associated receiver. Programming is carried out on the workshop side in the course of maintenance work with the help of a factory-located programming station. This tire pressure monitoring system proves to be less user-friendly.
  • Of the Invention is based on the object, a tire pressure monitoring system to create, which proves to be more user-friendly.
  • These The object is achieved by a tire pressure monitoring system with all features of claim 1.
  • further developments of the invention are in the dependent claims specified.
  • The Tire pressure monitoring system according to the invention Thus, starting from the generic tire pressure monitoring system a programming transmitter, which is now located in the vehicle itself and connected to the control unit in the central unit and is controlled by this. The control unit controls the programming transmitter in such a way that the selection of a particular transmission format and thus a specific code from the different ones in the storage unit discarded possible Codes using an acknowledgment signal between the monitoring unit and the control unit takes place. This acknowledgment signal is thereby as well as programming signals or the signals with the information transmitted to the tire pressure by radio.
  • With Assistance of this tire pressure monitoring system according to the invention On the one hand, they are an independent one Programming without external devices makes possible and thus a self-sufficient Handling the tire pressure monitoring system created. External programming during maintenance in a workshop is through the system of the invention not necessary anymore. The tire pressure monitoring system is able to even when changing a tire, for example, a tire from one manufacturer to another manufacturer's tire and For example, in a tire defect during a trip, independently the Adjustment or definition and thus the selection of the appropriate code from the available standing codes in the monitoring unit of the new tire. This leads to a much more pleasant and more reliable Tire pressure monitoring system. These reliability is doing especially well by the use of an acknowledgment signal, the correct dispatch or the reception of the correct radio signal, in particular with the Information on tire pressure confirmed, further increased. By this use of an acknowledgment signal on the one hand for confirmation and thus to the execution of the selection of a certain code and thus one certain transmission format is a very reliable and pleasant handling the tire pressure monitoring system according to the invention reached. Visiting a workshop to ensure the function the tire pressure monitoring system is not according to the invention more necessary.
  • According to a preferred embodiment of the invention, the tire pressure monitoring system according to the invention is designed so that with the aid of the programming transmitter and the programming receiver, a control signal is transmitted, with the help of the memory unit, a single transmission format and accordingly a single code from the plurality of stored codes is selected and this transmission format is used to generate a signal with the tire pressure information and to transmit this via the transmitter to the receiver in the central unit in the vehicle. In the central unit, this signal is received by the transmitter and identified in the control unit, which has a control function. The identification is possible in a simple way, since the transmitted signal has the selected and determined transmission format, which is necessary for a correct evaluation of the tire data. This correct transmission and evaluation of the transmission signal is understood as an acknowledgment and thus as a confirmation signal for a correct selection. Through this out With receipt, a very reliable tire pressure monitoring system is created, which largely excludes a malfunction and, moreover, is particularly easy to handle.
  • alternative It has proven particularly worthwhile that Tire pressure monitoring system to realize that not a single transmission format and thus one single code is selected by the received programming signal, but a small number of transmission formats or codes from the stored Codes selected and then sequentially transmit the tire pressure information be used in the form of a radio signal. It will turn upon receipt of an evaluable radio signal after its evaluation transmit an acknowledgment signal from the control unit in the vehicle to the universal monitoring unit and thereby the correct transmission or the correct selection of a code or transmission format confirmed. On Basis of the confirmation will be the monitoring unit subsequently controlled so that only this limited number at selected Transmission formats / codes are transmitted. Typically, this number is below 10 in particular according to the invention in the range of 5 codes or
  • Broadcast formats. This is a very reliable Tire pressure monitoring system given that very quickly and reliably information about the Tire pressure in particular allows its changes. By joining a a certain number of suitable transmission formats, it is possible to universal monitoring device to a particular manufacturer or vehicle type (e.g., with several different wheel sizes, different tire manufacturers or rim manufacturers) and thus an adjustment the transmission formats used to changed circumstances, e.g. when changing from summer tires to make winter tires on the same vehicle superfluous and thus the Handling the tire pressure monitoring system noticeably improve.
  • Furthermore it has proven to be particularly effective the tire pressure monitoring system form so that several stored codes in succession for transmission the tire pressure information can be used, whereby one and the same Information about tire pressure in different transmission formats in a row sequentially sequentially from the transmitter of the universal monitoring unit to the recipient transmitted in the vehicle become. The one from the receiver received radio signals are the control unit of the tire pressure monitoring system supplied in the vehicle, where the received radio signals are evaluated. Is the evaluation due to the appropriate transmission format or the corresponding code successful, an acknowledgment signal is sent via the programming transmitter in the Vehicle sent by the programming receiver in the universal monitoring unit Will be received. This received acknowledgment signal becomes the memory unit supplied the further transmission of the successive radio signals different Codes finished. This is the selection of a specific send format or codes with the help of the acknowledgment signal causes. The selection corresponds typically the last one sent, received and successful evaluated radio signal of a particular format / code. By this training of acknowledgment and selection of a transmission format is a very reliable working tire pressure monitoring system given, the most varied changes in particular by a tire change, especially by changing the rim but also by other circumstances For example, valve changes, in a simple and safe way adapts. Thus, a very comfortable tire pressure monitoring system is created.
  • It has proven particularly useful, with the help of the sensor in the universal monitoring unit, to monitor the tire pressure for changes and to determine the relevant tire pressure change (eg a pressure change> 0.3 bar) and, when the tire stops, the selection process, in particular with each other following sequential transmission of various stored codes to start. By this initialization of the selection process on the basis of a detected relevant tire pressure change at standstill of the vehicle or the tire is ensured that in the typical situations that require adjustment of the tire pressure monitoring system, such as a tire change or rim replacement, etc., an automated early selection of the appropriate Transmission formats from the stored codes triggered and carried out. This design of the tire pressure monitoring system ensures that a correct tire pressure signal is always reliably transmitted as needed. By this initialization based on the change in tire pressure is also ensured that when refilling the tire with compressed air and thus at a change in tire pressure, a new initialization of the tire pressure monitoring system is triggered and achieved, which in addition to the selection of the appropriate transmission format and the new set normalized tire pressure recorded is identified by a significant deviation, for example, by a defect in the tire, and reported accordingly as a warning to the driver. Through this training, the reliability and usability of the invention tire pressure Überwa given to a particular degree.
  • It has proven particularly effective the programming receiver train so that he puts in a so-called sleep state can be. This is done according to the invention in a special training the tire pressure monitoring system according to the invention then when the selection of the code is completed. Preferably this sleep state is then canceled and the state of the programmer in the normal operating state is offset when during the stoppage of the tire a relevant change in tire pressure (typically in the range of> 0.2 bar) is detected. In this case, the sleep state in which the programming receivers is not able to transmit a radio signal from the programming station received, transferred to the normal state, so that in the following he is in a position to appropriate programming signals and thus to receive acknowledgment signals. Due to the inventive design of the programmer or its activation and thus transfer to the sleep state or its activation from the sleep state is ensured that the energy consumption of the monitoring unit significantly reduced in the tire, without this adverse effect on the reliability and special handling of the tire pressure monitoring system has.
  • It has proven to be particularly advantageous to the programming station and the one or more programming receivers for sending and receiving DSS signals (direct spread spectrum signals) train. Here are the programming receiver or programming station designed so that it is specially designed to receive DSS signals low data rate are suitable. This makes it possible to transfer the transmitted Signals with a very high redundancy and thus as a redundant Sequence of many zeros and ones to realize that due the redundancy is a very simple realization of the programming station and the programming receiver, especially with regard to the antenna structures contained could be. By this is the special training of the programmer and programmer a very reliable one and simple tire pressure monitoring system given a universal use in a variety of vehicles allows.
  • in the The following is the tire pressure monitoring system according to the invention explained with reference to a system illustrated by way of example in the drawings.
  • 1 shows a schematic structure of the tire pressure monitoring system according to the invention with a universal monitoring unit 2 and a central processing unit 20 ,
  • The exemplary tire pressure monitoring system consists of a central processing unit 20 , which is arranged in the vehicle in particular centrally in the field of vehicle control devices.
  • This central unit 20 is in radio communication with several monitoring devices 2 , which are arranged in the wheels and thus on or in the tire so that they detect the current tire pressure and radio to the central unit 20 can transmit. This central unit 20 evaluates the radio signals and makes it possible to tell the driver information about the current tire pressure or a change in tire pressure. In this case, the driver is typically issued a warning that there is a pressure loss in a particular tire. With the help of this warning signal, the driver is reliably warned and severe accidents can be at least partially prevented.
  • In 1 is exemplary only a single monitoring unit 2 represented for the multiple monitoring units in the different wheels or on or in the tire.
  • The monitoring device 2 contains a sensor 3 for detecting the tire pressure. This is preferably designed as a microelectronic pressure sensor, which is also also able to detect temperature information, which proves to be very advantageous, since the temperature information is an indication of a possible negative pressure condition of the tire. Since these negative pressures lead to increased flexing and this can lead to the destruction of the tire, this information together with the tire pressure information is very important for the warning of the driver by means of the central unit 20 ,
  • The sensor 3 is with the storage unit 4 in the monitoring device 2 connected. The storage unit 4 has the function, the monitoring device 2 and, moreover, the information supplied to it from the sensor 3 prepare and process this information with the help of a sender 5 by radio to the central unit 20 to be transmitted in the vehicle. This is the transmitter 5 preferably implemented as a passive transponder, which has built-in antennas. The transmitter 5 is regularly integrated in the sidewall of the tire. In the storage unit 4 Several codes are stored. These codes represent various transmitter formats that are characteristic of a particular manufacturer, vehicle, type of tire, rim type, etc. With this variety of alternative formats and codes, it is possible for the monitoring device 2 with the multitude of Codes targeted using the storage unit 4 to realize that they are using different central units 20 can cooperate and pass on the relevant information about the tire pressure and possibly other information by using agreed codes or transmission formats.
  • The selection of one or more special codes from the plurality of available codes, which has an influence on the formatting of the emitted signals, takes place by adapting them, for example, to their carrier frequency, the modulation scheme, the data format and / or the encryption. This selection is made according to the invention using an acknowledgment signal between the central unit 20 and the respective monitoring unit 2 is exchanged. By this purposeful selection of one or less codes and thus transmission formats is a universal monitoring device 2 given.
  • With the help of the transmitter 5 sends the monitoring device 2 by radio the sensed data in the selected transmission format to the central unit based on the selected code 20 , The central unit 20 receives this radio signal from the transmitter 5 , which is realized as a passive transponder, with the help of a receiver 8th , This passes the received signals to the control unit 7 in the central unit 20 Continue in the vehicle. This control unit evaluates the information and forwards it to the output unit 10 for information of the driver. With the help of the output unit 10 The driver is informed about the current situation with regard to the tire pressure or a change in the tire pressure or with regard to the tire temperature and thus the risk of a tire defect.
  • The central unit 20 also has a programming station 9 on, with the control unit 7 connected is. Similarly, the universal monitoring device 2 with a programming receiver 6 provided with the memory device 4 connected is. The one in the central unit 20 integrated programming channel 9 is from the control unit 7 controlled so that upon receipt of an evaluable and correct radio signal with the sensor information, an acknowledgment signal from the central processing unit 20 to the monitoring device 2 is transmitted by radio. This acknowledgment signal is generated with the help of the programming receiver 6 received and the storage unit 4 forwarded. Once the storage unit 4 this acknowledgment signal from the central unit 20 gets fed, the storage unit stops 4 the sequential transmission of the sensed information in different transmission formats and thus the transmission of the sensed information using the different codes for determining a selection of a particular transmission format or an associated code. The most recently transmitted radio signal formatted according to a specific transmission format or code was transmitted by the control unit 7 in the central unit 20 successfully evaluated and interpreted, which by the described acknowledgment signal compared to the memory unit 4 is confirmed. Based on this confirmation is the memory unit 14 in the monitoring unit 2 now able to recognize that the last related broadcast format is the one selected. This selected broadcast format will be used exclusively in the future; other transmission formats are no longer used in this embodiment of the invention. A time-consuming and complicated transmission of several unspecific non-reliable transmission formats can thereby be avoided.
  • By this form of selecting a particular transmission format and thus the use of a particular code from the plurality of possible codes of the universal monitoring device 2 is a very reliable component of the tire pressure monitoring system according to the invention created that allows the driver a very reliable and up-to-date information about the tire pressure and possibly the tire temperature.
  • The selection of a transmission format for each monitoring device 2 on the vehicle requires no outside help, for example, as part of a workshop visit, which proves to be very pleasant for the driver.
  • Also proves the selection as very reliable, so that the information quality of the driver very much is high.
  • The programming station 9 in the central unit 20 in the vehicle and the programming receiver 6 in the monitoring units 2 are implemented as DSS transmitter or DSS receiver. These work according to the direct spread spectrum transmission method (DSS method). This special transmission method makes it possible to transmit information very reliably with a very low data rate. As a result, the transmission of the acknowledgment signal for selecting the particular transmission format or the corresponding code is very simple and reliable. By using this special transmission method, it is possible to use redundant signals that allow for the use of very simple and small antenna structures in the programming transmitter 9 but also in the programming receiver 6 enable. This makes it possible to program the transmitter 9 and the programming receivers 6 very easy and inexpensive to realize.
  • The programming receivers 6 but also the programming station 9 are thereby realized or are controlled so that they are controlled by the control unit 7 or the storage unit 4 can be placed in a sleep mode (sleep mode) in which they consume no or significantly reduced energy, which drastically increases the lifetime or the possible working time of the tire pressure monitoring system until the next battery change. From the sleep state, these programming receivers can 6 or the programming station 9 be woken up in the normal state, and allow in this state, the transmission of the corresponding signals. The awakening process is determined by the coincidence of certain events. These events are on the one hand the detection of a change in the tire pressure by more than 0.1 bar and on the other hand the statement that the vehicle is not in motion or the wheel with the monitoring unit is at a standstill. If these two conditions are given together, then the programming receiver becomes 6 awakened from his sleep state and transferred to the normal state. This normal state is maintained until the successful selection of a particular transmission format has been successfully completed. Then the programming receiver becomes 6 through the storage unit 4 again transferred to sleep. In a corresponding manner, this is also done with the programming station 9 in the central unit 20 , However, the control is not from the storage unit 4 but from the control unit 7 performed.
  • The detection of the tire pressure change is done with the help of the sensor 3 and the storage unit 4 carried out. The monitoring device 2 is provided with a power unit, not shown, which gains energy from the movement of the tire or the wheel. Various such electromechanical energy winning systems are available to those skilled in the art. From the measure of the energy gain can be concluded on the standstill of the wheel or the tire and thus the vehicle. Based on this information is about the storage unit 4 aware of the change in tire pressure, the sleep state is purposefully lifted.
  • On the one hand, this embodiment of the tire pressure monitoring system provides a very convenient arrangement, which allows the transmission formats to be used to be adapted by the monitoring units 2 when changing the valves, rims and / or tires in a very reliable manner, without requiring a stay in a workshop is necessary. This comfortable adaptation of the codes to be used respectively transmission formats also always allows a very reliable information of the driver about the current state of the tire respectively the tire pressure or the tire temperature. This is also done in a very durable and communication-proof way.
