- Results in the actuating element 20 in step 104 performed check that the existing in memory 25 Reference serial number 16 not with the one with the search signal transmitted serial number matches, that turns on Actuator 20 in a sleep state, step 101. It takes part in the subsequent communication with the Device 10 no longer part.
- the microprocessor 24 replies in the form of a Contact signal.
- the contact signal is a short one simple signal, for example the group number 26 of the associated actuator 20 in bit-coded form. Like the search signal, it is unencrypted. His
- the processor 24 initiates transmission after the expiry of a for the actuator 20 characteristic period Input of the search signal.
- the sending of the contact signal then takes place in a time window with a predetermined length, Step 105.
- the length of the time window is such that a safe assignment of a contact signal on both sides the actuators 20 as possible on the part of the device is.
- Figure 3 illustrates the function of the actuators 20 following the examination of step 104 in graphic representation.
- the abscissa denotes one divided into eight time windows F0, ..., F7 Time axis t, which with the input of the search signal in the Actuators begin.
- the ordinate gives that characteristic group number 26 of each Actuator 20 on.
- Device 10 eight actuators 20 with the group numbers 0 to 7 assigned. Of these, the actuators 20 with group numbers 2 and 6 when sending one Search signals by the device 10 in the field of action Search signals present. Both operating elements 2 and 6 respond accordingly to the search signal Sending a contact signal according to step 106.
- Im underlying example corresponds to the time of Transmission of the contact signal, i.e.
- the microprocessor 13 now determines those present Actuators 20 by checking which ones Time windows F0, ..., F7 contact signals have been received, Step 106. He checks by repeating m times as many - m - time slots as actuators at most can be assigned, step 107. Attendants Actuators 20 are by corresponding entries noted in memory 15, step 103. If none Actuating element 20 determines, an abort signal is issued, Steps 108, 111. After determining the ones present Actuators 20 determine the Mode of operation, step 109; The operating modes are possible Assigning and teaching as well as other functions such as deleting, Block, release and the like The microprocessor 13 checks this purpose, whether a command to select the operating mode There is learning.
- the Microprocessor 13 makes a decision with which of the Actuators 20 present another Assignment communication is to take place, step 110.
- the basis for the decision can be, for example Ranking of the actuators 20, in which the Actuators 20 about different Functional scope are granted. For example, at Certain use in motor vehicles Actuators 20 a limited geographical Area within which the vehicle is assigned the actuator is functional. That among the Actuators 20 selected Actuating element informs the microprocessor 13 Sending his group number. All if necessary present further actuators 20 with others Group numbers take part in the subsequent communication no longer part.
- the device 10 then subjects the selected one Actuator 20 of a matching test. In the example, this is done using the known challenge-response method.
- the device 10 sets here on his Transceiver 11 an encrypted challenge signal from that for the selected actuator 20 is determined and executed only by this, step 112.
- the device-side microprocessor determines 13 a target response signal. The calculation is made from the Challenge signal according to a predefined algorithm use of the cryptic stored in the memory 31 Key and the available in memory 15 Manufacturer codes 17.

- the Challenge signal is meanwhile from the Transmitting / receiving device 21 in the actuating element 20 received in the decoder 22 with the aid of the cryptic key 31 decoded and the microprocessor 24 fed.
- the latter derives from the received challenge signal in the same way as the device side Microprocessor 13 a response signal and sends it to the device 10 back, step 114.
- the transceiver 11 decoded again in the decoder 12 and the microprocessor 13 fed.
- the latter compares it with the previously determined one Target response signal, step 116. Both are not correct match, device 10 and actuator 20 are each other not belonging.
- the processor 13 then directs corresponding ones
- follow-up action for example, he locks the device 10 against use, step 117.
- an assignment is not made is, for example by visual or acoustic display.
- connection measures can also be provided, for example, a repetition of the assignment procedure starting with step 112 or with step 102.
- the device 10, 20, 30 described above permits by Teaching also the assignment of new, especially brand new Actuators 20 to an existing device 10. Die Such a reassignment is carried out in FIG. 4 as Flow chart shown. From the in each process step given addition in the form of the letter G or B. again it can be seen whether the relevant step in the Device 10: G or in actuator 20: B takes place. Teaching actuators to be reassigned 20 initially runs like the assignment shown in FIG units already known to each other and starts with the Triggering a mapping communication according to step 100. It this is followed by the determination of the range of action of the device 10 known actuators 20 according to the Steps 102 to 108. In step 110, however, the Teaching mode defined, step 200.
- the change between the operating modes assignment and teaching expediently by the user with the help of Input device 17.
- the microprocessor then checks 13, step 202, whether a particular one, as Main actuator treated actuator 20 is present.
- the main operating element is, for example Actuator with group number 0, which accordingly after receipt of the search signal in the first Time window F0 sends back a contact signal. Does the Microprocessor 13 determines that the main actuator 20th is not present, it cancels the teach mode.
- step 202 If the check in step 202 reveals that the Main actuator is present, it becomes one Allocation correctness check, step 203, according to steps 112 to 118 subjected. If there is a fault Assignment, the teach mode is aborted, step 201. Proper assignment of main actuator and Detected device, the microprocessor 13 checks using the Directory 18, whether free, not yet Actuator-assigned group numbers available are, and an assignment of further actuators 20 to the device 10 is even possible, step 204. In the case a negative finding, it breaks the learning process again from step 201. If the determination is positive the microprocessor 13 causes a zero search signal to be emitted, Step 205.
- the zero search signal corresponds to in its structure is a search signal, as it is in normal operation Step 104 is discontinued, and is also unencrypted.
- the serial number there is one 20 brand-new serial numbers for brand-new actuators.
- binary serial numbers it in a simple way e.g. from a sequence of zeros. Are in the effective range of radio link 30 Brand new actuators 20, they receive the zero search signal.
- the device 10 checks in the meantime the receipt of on the transmission of the zero search signal incoming contact signals, step 208. Provides the Microprocessor 13 determines that no contact signal received, he cancels the learning process, Step 201. On the other hand, the microprocessor 13 sets the Input of one caused by a zero search signal Contact signal in a time window, he causes the Issuing a control signal, step 210, which immediately all others who may be present Actuators 20 placed in idle state, i.e. also those who have a contact signal in a later Submit time window. The microprocessor 13 repeats then steps 205 to 210 with the determined Actuators 20 a predetermined number of times, i.e.
- the microprocessor 13 initiates the transfer the serial number 16, the cryptic code key 31, and one of the actuating element 20 in the future assigned characteristic group number 26.
- the transmitted code information 16, 26, 31 does that Actuator 20 in the intended up to at this point there are still free spaces in memory 25.
- code information 16, 26, 31 an acknowledgment signal to the device 10. It can be for example, the manufacturer number 27.
- Step 220 the device 10 issues a wake-up command, by means of which the further, if any, in Actuating elements 20 in the sleep state again be activated. It can now learn further actuators 20 to be reassigned Repeat steps 202 and then connect.
- Actuators While maintaining the basic idea, Actuators based on the time of their response to identify a search signal, the prescribed device in various ways design and modify. For example, this applies to the Structure of device and actuators for which Design and sequence of process steps, for example regarding the implementation of the Accessibility check, or for the form and structure the code information exchanged over the radio link.
