Definitions
- the invention relates to a method for identifying a sensor device for speed measurement for a wheel of a vehicle according to the preamble of claim 1. Furthermore, the invention relates to a sensor device for measuring speed for a wheel of a vehicle according to the preamble of claim 9. Finally, the invention relates to a vehicle with such a sensor device according to the preamble of claim 14.
- the sensor devices discussed here serve to determine the rotational speed of a component of a vehicle.
- they are used in the field of speed measurement on wheels. These are accordingly referred to as wheel speed sensors or wheel speed sensor.
- Different measuring principles are used, for example optical, electrical or inductive methods.
- a determination of the speed of a single wheel in the driving operation of the associated vehicle is usually continuous. This is particularly important for stabilizing the driving operation or for braking. For example, electronic stabilization systems as well as antilock braking systems and similar systems are dependent on measured values of the individual wheel speeds. Accordingly, high demands are placed on reliability and accuracy of the sensor devices.
- each sensor device is assigned a unique identifier for identification, so-called identification means. For this purpose, corresponding number codes, bar codes or also matrix codes are applied to the sensor devices or housings thereof. This can be done for example by printing, laser marking or similar.
- the reading can be done for example by a person or by appropriate readers, such as code scanners. Both the readers and corresponding readers can be summarized under the term reader. Accordingly, the features commonly used for identification are optically readable. This is done without contact, but requires a direct line of sight.
- a disadvantage of the known method for the identification of sensor devices is that on the one hand a visual connection between the sensor device and the associated laser must exist and on the other hand dirt, abrasion and the like can reduce the readability of the identification means beyond recognition.
- the object of the present invention is therefore to provide a method for identifying sensor devices and a corresponding sensor device, in which the disadvantages of the prior art are eliminated.
- the identification means is read out by radio.
- This is in particular a wireless transmission.
- This identification means is assigned to a sensor device for measuring the speed of a wheel of a vehicle.
- a reading by radio is in particular contactless.
- An advantage of reading by radio is that no visual must exist bond between the means of identification and the reader or reader. It is thus possible, in particular, to read the identification means in tight spatial conditions and without direct visual contact. Superficial changes to the sensor device, which usually complicate or prevent the reading out of the usual identification means, are generally unproblematic for identifiable by radio identification means.
- the identification means sends an electrical and / or magnetic signal for identification. Accordingly, a corresponding signal can be received by the corresponding reader or reading device, which can be used to identify the sensor device. The transmission by radio ensures that the sensor device can be identified by means of the identification means.
- data is transmitted by the signal.
- the data transmitted by the signal are in particular identification data, such as an identification number or an identification code.
- identification data are transmitted, such as at least one number or a code, in particular a numeric and / or alphanumeric code. In this way, an identification of the sensor device is possible, which is associated with the identification means.
- At least one transponder or electronic transponder is preferably provided as the identification means.
- an RFID transponder Radio Frequency Identification Device transponder
- Such a transponder is an electronic unit for wireless reading.
- An RFID transponder is read out by radio. Data can be transmitted which can be used, in particular, to identify the RFID transponder and thus an associated device.
- RFID transponders are known for different purposes, for example for use as anti-theft systems in department stores. As a rule, however, they do not permit any concrete identification, but merely a presence detection of an RFID transponder in an area.
- An RFID transponder as Identification means can preferably be read out by electromagnetic radiation, in particular wirelessly.
- the identification means includes at least one micro-chip as the active element.
- This ikrochip preferably allows the identification by transmitting identification data by radio.
- the microchip can perform additional tasks in addition to the identification, such as in particular a storage and / or transmission of measurement data. These measured data may be measured data of the associated sensor device or the like, in particular rotational speed data or the like. These data are transmitted to the means of identification. This is preferably done by a wired or wireless connection, such as an electrical coupling, a radio link or the like, between a transducer of the sensor device and the identification means.
- the identification means is supplied externally with energy.
- the supply is preferably wireless, in particular by radio.
- This is in particular electrical energy which is received by means of an antenna.
- This energy is used to operate the identification means.
- a radio signal is radiated, which is temporarily stored by an electrical energy storage of the identification means, for example a capacitor or a battery.
- This cached energy is used to operate the identification means, ie in particular to generate a signal for identification and to send by radio. Accordingly, then identification data or the like can be transmitted.
- the signal in particular the radio signal of the identification means
- the identification means is coupled into an electrical vehicle electrical system of the assigned vehicle.
- the identification means may preferably be arranged for example in spatial proximity to at least one electrical line or an antenna of the electrical system.
- an electromagnetic coupling causes at least a part of the signal to carry the means of identification into the electrical system. see conductor or the antenna is coupled.
- This signal is then correspondingly available in the electrical wiring of the electrical system.
- the identification means is read out by the on-board electronics. By the on-board electronics evaluating the electrical, coupled-in signal or even a signal transmitted by radio, data line or the like from the identification means, its data can be further processed.
- the correct installation of at least one sensor device can be checked.
- a correct alignment or positioning of the sensor device may be a prerequisite for achieving a certain degree of coupling into the vehicle electrical system.
- a correct positioning or correct installation of the sensor device can be ensured.
- a sensor device may in particular be a so-called wheel speed sensor. This is usually used to determine the speed of a wheel, for example by means of an inductive, optical or other suitable measuring method.
- the sensor device is also assigned as a rule a non-contact readable identification means.
- the sensor device according to the invention is characterized in that the identification means can be read by radio. This offers over the solutions known from the prior art the advantage that a direct line of sight is not required. A reading by radio thus also allows use in confined spaces. For example, an expansion of the respective sensor device for identification of the same can thus be avoided as a rule. Also superficial contamination or damage to the known identification means of the solution according to the invention usually do not harm.
- the identification means is designed as a transponder.
- this is an electronic transponder.
- an RFID transponder Radio Frequency Identification Device transponder
- the latter is an electronic circuit which transmits by radio at least one signal, an identification code or the like.
- the identification means preferably has at least one microchip and at least one antenna. This enables identification.
- the identification means is designed to store data for identification and / or to transmit.
- data is transferred which enables unambiguous identification of a specific sensor device.
- identification codes or the like are transmitted, for example in the form of a character string.
- the identification means can store and / or transmit measurement data.
- measurement data may be, for example, rotational speed data, which may preferably originate from the associated sensor device.
- care must be taken to transmit the data from the sensor device to the identification means. This can be done for example by radio, by electrical data line or in a similar manner.
- the transmission or storage of measurement data takes place in addition to the identification data. This ensures that a link between identification data on the one hand and measurement data on the other hand can be established.
- concrete connections between a measured value and corresponding transducers can be established. For example, a speed value can be assigned to a specific sensor.
- the identification means does not have its own energy supply.
- the identification means can therefore be supplied in particular from the outside or from the outside with electrical energy.
- electrical energy is transmitted by radio and received by means of an antenna from the identification means.
- the identification means has for this purpose a buffer for electrical energy, preferably a capacitor or a battery. This energy can be used to operate the identification means or its microchip.
- the radio signal is thus generated and transmitted.
- the sensor device is associated with a housing. This serves in particular to protect the components of the sensor device as well as the identification means or for attachment to a vehicle.
- a plug connection is typically provided, which serves to connect the sensor device to the electrical system of the vehicle via a cable.
- the identification means can be assigned to both the housing and the connector as well as the cable. With each of these components, the identification means may be connected, for example by sticking or inserting into an opening or recess. It may also be only a part of the identification means, such as in particular a microchip or the like, inside the housing or for example in a depression thereof. By coating, the identification means is optionally protected against damage. A part of the identification means, such as an antenna or the like, can also be arranged outside, in particular in the region of the respective wall. Likewise, a part of the component may form an antenna or be integrated in other ways in the signal transmission. This ensures on the one hand protection of the identification means and on the other hand ensures secure transmission.
- a vehicle with at least one sensor device for speed measurement according to the above descriptions.
- the sensor device and in particular the at least one sensor device are preferably provided for measuring the rotational speed of a wheel.
- the vehicle is designed in particular for carrying out a method as described above. This ensures that appropriate measures for reading the identification means can be made.
- the identification medium may in particular be arranged on the vehicle such that it is suitable for coupling the signal into an electrical system of the vehicle.
- the identification means can be preferably coupled by radio or electrically to at least one electrical component of the electrical system.
- the identification means or an antenna thereof is to be arranged in sufficiently close proximity to an electrical component of the electrical system, for example, a line or an antenna of the electrical system. Then a sufficient coupling can take place.
- the identification means is preferably readable by the on-board electronics. This ensures that the on-board electronics are also informed about the presence and possibly measurement data of the identification means. For example, it can be ensured by evaluating the sufficient coupling by radio to the electrical system that a correct positioning of the identification means has been carried out.
- Fig. 1 shows a sensor device according to the invention for speed measurement for a wheel of a vehicle.
- FIG. 1 shows a detail of a device 10 for determining the rotational speed of a wheel (not shown).
- the device 10 includes a sensor device 12 for the actual speed measurement.
- the sensor device 12 is therefore also referred to as a wheel speed sensor.
- a mitzustten can be determined by optical or inductive measurement, the relative movement of a mitzustten with the wheel not shown toothed bar 14.
- regular elevations and depressions 16 of the rack 14 produce a periodic signal of pulses in the sensor device 12. This pulse signal is proportional to the movement of the rack 14 and thus to the speed of the associated wheel.
- the sensor device 12 is usually installed in a bearing element 18 of the associated vehicle.
- the bearing element 18 in the present case on a breakthrough 20.
- the sensor device 12 has a housing 22, which is substantially cylindrical in this case.
- the housing 22 of the sensor device 12 is then inserted into the opening 20 of the bearing element 18.
- the housing 22 is secured in the aperture 20 to prevent unwanted movement.
- the sensor device 12 with the housing 22 is almost completely surrounded by the bearing element 18 in this case. Only at the right end portion in the drawing, a short portion of the housing 22 is arranged with a connector 24 outside.
- This connector 24 connects on the one hand the sensor device 12 and on the other hand, a cable section or a corresponding cable 26.
- the cable 26 is used to connect the sensor device 12 with an on-board electronics of the vehicle. About this cable 26, the actual measured values of the sensor device 12 are transmitted to the speed of the associated wheel. In addition, the cable 26 is used to power the sensor device 12.
- the solution according to the invention with three alternative positions 28, 30 and 32 for corresponding identification means is shown here.
- the identification means 28, 30, 32 may be formed virtually identical in all cases. This is an identifiable by radio identification means, in particular an RFID chip.
- the identification means 28 is attached directly to the housing 22 of the sensor device 12 in the first case. For this purpose, for example, a depression in the housing or a recess may be provided. For the protection of the identification means 28 then material can be applied to the cover. Due to the readout by radio, an identification of the sensor device 12 via the identification means 28 can also take place in the installed state.
- the identification means 30 may be assigned to the part of the plug connection 24 which is firmly connected to the sensor device 12. In this case, it is advantageous that the identification means 30 is arranged further outside of the holding element 18 in the region of the plug connection 24. Often connectors 24 are made of plastic or similar material, so that a better transparency for electromagnetic waves is given as in metallic components. In the event that the identification means 30 is arranged on the part of the detachable from the sensor device 12 portion of the connector 24, however, a unique identification of the sensor device 12 is possible. The installation of the sensor device 12 is already determined during the first installation as part of the production of the vehicle. Accordingly, a unique identification of the sensor device 12 is possible. Incidentally, the plug-type connections 24 can typically only be used for exactly one sensor type, so that as a rule no confusion with other sensor types can occur here.
- the third position of the identification means 32 in the region of the cable 26 can be assumed. This provides similar advantages as the positioning in the region of the connector 24. Since the cable 26 is fixedly connected to the cable-side part of the connector 24, the assignment of the sensor device 12 to the corresponding connector 24 and the cable portion 26 is already set during manufacture of the vehicle , Accordingly, an unambiguous identification of the sensor device 12 can take place.
- a corresponding, not shown here reading device is brought into the vicinity of the identification means 28, 30 and 32 respectively.
- the reader can emit electrical energy by radio.
- the identification means 28, 30, 32 By appropriate reception and intermediate storage of the energy by the identification means 28, 30, 32, the latter is enabled to emit a radio signal on its own.
- RFID chips do not have their own energy source.
- the identification means 28, 30, 32 For receiving the electrical energy, the identification means 28, 30, 32 has a corresponding antenna, which is not shown here.
- the radio signal of the identification means 28, 30, 32 is then used for the transmission of data, in particular identification data.
- the radiation usually takes place via the same antenna as the energy intake.
- the corresponding radiated radio signal is again recorded by the reader.
- the radio signal contains corresponding identification data, in particular a unique code number or the like, an identification of the sensor device 12 can take place. If necessary, a comparison with a database or the like must be done to obtain, for example, production date, place of production, test result or the like.
- the identification means 28, 30, 32 can also send additional data, for example measurement data.
- additional data for example measurement data.
- a corresponding coupling must be made to suitable measuring elements, for example to the sensor device 12.
- a measured rotational speed can thus be linked to the corresponding identification data.
