- a left antenna arrangement 10 On the left side of a motor vehicle shown in plan view, a left antenna arrangement 10 is accommodated between the left front and rear door. When polling the left outer space, the left antenna arrangement 10 emits an antenna field 16 for the outer space query left and an antenna field 14 oriented towards the interior. A transponder 11 is located within the antenna field 16 for the external space query on the left, which in this case exchanges signals with the left antenna arrangement 10. The antenna field 14 oriented towards the interior extends beyond the right side of the motor vehicle. This field, which is sufficient in addition, is to be equalized by a compensation field 18 for the left-hand external query, generated by a right-hand antenna arrangement 12.
- the left antenna arrangement 10 consists of a first left antenna 21 and a second left antenna 22, which are arranged orthogonally to one another.
- the first left antenna 21 is controlled by a driver 24 for the first left antenna
- the second left antenna 22 by a driver 25 for the second left antenna.
- the right antenna arrangement 12 is formed by a first right antenna 31 and a second right antenna 32, again arranged orthogonally to one another, with the associated drivers 34 for the first antenna on the right and a driver 35 for the second antenna on the right.
- the drivers 24, 25, 34, 35 exchange signals with a controller 40.
- An interior logic 42 and an exterior logic 44 are provided in the controller 40 for carrying out the interior monitoring and the exterior monitoring.
- the controller 40 exchanges signals with a memory 46 in which a current 111 of the first left antenna 21, a current 112 of the second left antenna 22, a current Irl of the first WO 00/08280 "-, -., -.
- the controller 40 is supplied with two opening signals, doors left 48, two opening signals, doors right 50, and an engine start signal 52 as further input variables.
- the exemplary embodiment according to FIG. 3 differs from that of FIG. 2 in that the left antenna arrangement 10 is expanded by a third left antenna 23 with an associated driver 26 for the third left antenna.
- the right antenna arrangement 12 also has a third right antenna 33 with an associated driver 36.
- a current 113 of the third left antenna 23 and a current Ir3 of the third right antenna 33 are additionally stored in the memory 46.
- FIG. 4 shows the time profile of a current IrlAr of the first right antenna for the outside space query on the right, and a current IllAr of the first left antenna for the outside space query on the right.
- the waveforms of these two currents are inverted binary.
- the outlined rectangles (binary signal) are the envelopes of the sinusoidal current curve.
- Left and right antenna arrangements 10, 12 are accommodated in the so-called B-pillar of the motor vehicle, which is located between the two side doors in a 4-door car. At least one antenna of the respective antenna arrangement 10, 12 is used both for the interior query and for the exterior query. In the exemplary embodiment according to FIG. 2, the two antennas 21, 22 and 31, 32 of each antenna arrangement 10 and 12 are used both for indoor and outdoor polling. In the exemplary embodiment according to FIG. 3, it is the second antennas 22 or 32 of the antenna arrangements 10 or way 12, which are controlled both in the interior and in the exterior query.
- the respective antenna arrangements 10, 12 of the queried side and the transponder 11 exchange signals. If the driver wants to get into the vehicle, he pushes the door handle on the left. A corresponding opening signal 48 doors left activates the corresponding exterior logic 44 in the controller 40 for the left exterior query. For this, the left antenna arrangement transmits
- antenna arrangement 10, 12 is encrypted due to the security requirements, for example according to the so-called challenge response method or the rolling code method.
- the field distribution shown in FIG. 1 results when the left antenna arrangement 10 is activated for a left exterior space query.
- the antenna field 16 located on the left side of the vehicle is desired for querying the outside space on the left, but not the antenna field 14 oriented toward the interior, which can also extend to the right side of the vehicle.
- the device according to the invention is intended to prevent the antenna field 14 which is oriented towards the interior and which emerges on the right-hand side of the vehicle in this constellation for communication with a transponder 11, which is located on the right side of the vehicle.
- the right antenna arrangement 12 sends an interference field 18 for the outside space query on the left.
- the generation of this interference field 18 is selected so that when the interference field 18 and the antenna field 14 oriented towards the interior are superimposed, a resulting field is produced which no longer contains the query information typical for the left side for the transponder 11 of the left antenna arrangement 10 includes.
- the information exchanged with the transponder 11 is generally binary in connection with a sinusoidal carrier signal of, for example
- This binary-coded information is to be influenced on the right-hand side by the interference field 18 in such a way that, for example, there is a continuous field without an O / l change.
- the right antenna arrangement 12 in a logically inverting manner with respect to the useful signal of the left antenna arrangement 10, illustrated by way of example in FIG. 4, so that with a suitable choice of the coil current amplitude (current peak-peak of the carrier signal) a continuous field is created on the right side .
- the right antenna arrangement 12 could also be driven to generate the interference field 18 in the sense of noise or out of phase with the user-side current.
- the current amplitudes are stored in the memory 46 for each antenna and type of query.
- At least one of the antennas of the antenna arrangements 10, -_2 is also used for an interior query.
- the controller 40 detects the engine start signal 52 and uses it to recognize the interior logic 42 in the sense of the interior query.
- the antenna arrangements 10, 12 carry out a signal exchange with the transponder 11 located in the interior. If the transponder 11 sends back a signal recognized as valid, the user is recognized as authorized to drive.
- the components necessary for the operation of the vehicle are activated.
- the left and right antenna arrangements 10, 12, which each cover the entire interior, are preferably controlled in succession.
- the first and second antennas 21, 31; 22, 32 controlled both for the interior query and for the exterior query right / left.
- a current value (coil current amplitude peak-peak) is stored in the memory 46 for each of these three operating modes.
- the current 111 of the first left antenna 21 thus has three values: the current of the left first antenna for the outside space query on the left (IllAl), the current of the first left antenna for the outside space query on the right (IllAr) and the current of the left first antenna for the inside space query (Uli). The same applies to the other antennas 22, 31, 32.
- the signal exchange with the transponder 11 takes place, inter alia, via this first left antenna 21.
- the current IllAl stored for this operating mode has a relatively high value.
- the first left antenna 21 generates an interference field for the outside space query on the right.
- the corresponding current value IllAr is to be chosen lower than that for the outdoor query on the left.
- a current Uli must be specified in such a way that the entire interior of the motor vehicle is reliably detected.
- the other current values must be stored in a corresponding manner.
- the current for the external query on the left IrlAl is to be selected to be smaller than that for the external query on the right (IrlAr).
- the second antenna 22 or 32 is always used both for the interior query and for the exterior query.
- These second antennas 22, 32 must in turn cover three operating modes with the associated three current values in accordance with the antennas according to FIG. 2, so that three current values are stored for each of the second antennas 22, 32 (I12A1, I12Ar, 1121; Ir2Al, Ir2Ar, Ir2I ).
- the first antennas 21, 31 are only used for the right / left outside space query, so that two current values are to be stored in the memory 46 for this purpose, one for generating a useful field, in the other case for generating an interference field.
- the third antennas 23, 33 only take over the interior query.
- the first antennas 21 for the external interrogation can be an air coil, which together with the second antennas 22, 32 form a so-called twin-loop antenna.
- First and second antennas 21, 31, 22 and 32 are driven out of phase by 90 °, so that a rotating magnetic field is created.
- Ferrite coils can be used as the second antenna 22, 32.
- the ferrite coil of the second antennas 22, 32 is mounted in the B-pillar.
- the third antennas 23, 33 for the indoor Space detection are also ferrite antennas and can be arranged on the floor, for example in the driver's seat.
- FIG. 5 describes the sequence of the operating mode of a device according to the invention.
- the queries are started, step 101, in that the controller detects a signal change in an input signal (opening signal 48/50 doors left / right, engine start signal 52).
- the three operating modes (exterior right / left query, interior query) can be assigned to these input signals.
- query 102 it is determined whether the input signal causing a signal change was the engine start signal 52. In the affirmative, the controller 40 loads from the memory 46 the current control values for the interior query (Ilnl, IrnI), step 103.
- the interior query is then carried out with the values loaded from the memory 46, step 104.
- a query 106 follows whether the doors on the left have been operated. If this is the case, the controller recognizes that the outdoor query on the left has to be started. It loads the current values for the external query left IlnAl, IrnAl from memory 46, step 107. If the left doors have not been actuated, an actuation of the right doors is queried, query 109. If so, the outside query must be carried out on the right. For this purpose, the corresponding current values IlnAr, IrnAr must be loaded from the memory 46. With the current control values Iln, Irn selected in this way, the external space query is carried out, step 108. Depending on a signal change which is considered to be permissible issued either a driving authorization (for the interior query) or an access authorization (for the exterior query), step 105.
