Definitions

  • the invention relates to a method for operating a hand-held transmitter for controlling vehicle functions with the features of the preamble of patent claim 1.
  • a method with these features can be derived from the mode of operation of an infrared handheld transmitter supplied for remote control of functions in vehicles manufactured by the applicant.
  • the output signals that can be emitted by this hand transmitter essentially consist of a code component and a maintenance component.
  • a code portion a relatively short coded message is transmitted from the transmitter to a vehicle-mounted receiver in a known manner, which enables z. B. to activate a central locking in the unlocking or locking direction or even from a greater distance from the vehicle.
  • the maintenance component which in the vehicles equipped with a convenience lock also enables the closing of windows that are still open after leaving the vehicle and the sunroof by means of their electric drives, is only emitted for as long as the transmit button on the handheld transmitter is continuously longer than a predetermined period of time immediately after the radiation of the locking code signal is recorded, that is, only for the desired duration the window or sunroof closing movement.
  • the latter only sets after a certain period of time, e.g. B. 0.25 sec after the start or after receiving the maintenance signal on the vehicle, as well as the need to hold the transmit button already represents a security measure.
  • the maintenance component consists of repeated clock pulses, which are transmitted at constant intervals with the intensity or signal level unchanged compared to the code signal.
  • the output power of the handheld transmitter and its range therefore remain the same (see Fig. 2).
  • the characterizing features of method claim 1 indicate an inventive solution to this problem.
  • this solution it is e.g. B. irrelevant whether the output signal for controlling the convenience closing drives z. B. is activated via a separate key of the handheld transmitter following a previous actuation of a code signal transmission key, or whether only a single transmission key is provided.
  • the receivable output power can be determined simply by selecting the button.
  • a hand-held transmitter is known (DE 38 06 130 A1), the output power of which is variable depending on the strength of the ambient light.
  • One possibility is to reduce the electrical output power of a signal source by connecting a resistor - which forms an electrical folder - in one step.
  • Another possibility is to provide two signal sources next to each other in the same handheld transmitter, one of which can emit unfiltered or unimpaired at full power, the other of which can only emit through a continuously upstream filter or with reduced power.
  • Another possibility with two signal sources can be realized by activating them together for a long range and switching off one of them to reduce the range.
  • dialog control of the receivable output power of the hand-held transmitter is possible as a function of a switching signal with a long range that is transmitted by the vehicle itself after complete reception of a suitable code signal and can be received and evaluated in the hand-held transmitter.
  • suitable variable signal filtering could also be provided, e.g. B. by switching on a suitable depending on the signal carrier type (infrared, ultrasound, radio) selected Filters in front of the signal output during the emission of the output signals controlling the drives.
  • signal carrier type infrared, ultrasound, radio
  • the receivable output transmission power p of a hand-held transmitter - which corresponds to its range - is plotted in a highly schematic manner over a time axis t when a transmit button is pressed continuously.
  • the waveform begins when the send button is pressed.
  • the abbreviations ZV / EDW and KB stand for locking devices or control elements of a central locking system / burglary-theft alarm system or for drives for comfort controls.
  • FIG. 1 shows that, according to the method according to the invention, with a constant waveform with respect to the pulse train, the amplitude of the pulses of the maintenance component A is significantly reduced, approximately by 50%, compared to the amplitude of the pulses of the code component C.
  • FIG. 3 shows a partially cut-open view of a hand transmitter 1 for infrared rays, which can be activated manually via a single transmission button 2.
  • a hand transmitter 1 for infrared rays, which can be activated manually via a single transmission button 2.
  • it includes an automatically controllable switching element 3 with a changeover contact 4 and a first infrared transmitter diode 5 and a second infrared transmit diode 6 as a signal source, which can be controlled alternately via the changeover contact 4.
  • the first infrared transmitter diode 5 is arranged behind a transparent cover 7 in the housing of the handheld transmitter 1, which does not significantly reduce or attenuate the transmit (light) power that can be emitted by the transmit diode 5 and can be received by a downstream receiver.
  • the second infrared transmitter diode 6 is arranged behind a cover 8 which is also transparent but absorbs part of the transmission power. Therefore, even with identical design and power consumption of the two signal sources or transmitter diodes 5 and 6, the transmit power emitted by the latter can only be received in a weakened manner by a downstream receiver.
  • the automatically controllable switching element 3 will switch its changeover contact to the transmitter diode 6 if and only after the radiation of the code signal or portion marked in FIG. 1, the power / range-reduced maintenance signal is to be emitted.
  • This process can be controlled by the program sequence of the hand-held transmitter on the software side or purely time-dependent via a timer (timer, clock), because with the present transmitter type the temporal extension of the code signal to be emitted and thus the time period between the start of the transmission button 2 and the time of the range switch is always constant.
  • timer timer, clock
  • an automatically controllable switching element 3 ' accordinging to FIG. 4 , which can connect a series resistor 8' to a single transmitter diode 5 'of a handheld transmitter, not shown, which then limits the power consumption of the transmitter diode 5' compared to the basic position shown and thus also to be regarded as a filter for the receivable output power.
  • FIG. 5 an arrangement is sketched in a highly simplified manner in FIG. 5 , in which an automatically controllable switching element 3 ′′ of a hand-held transmitter 1 ′ - as shown in FIGS. 3 and 4 - can be activated in dialogue with a vehicle-mounted transmitter with a long range.
  • a vehicle F is only partially indicated here as a dashed frame.
  • a vehicle-mounted receiver 9 with a downstream control device 10 and a transmitter 11 controllable by the latter are arranged therein.
  • the control unit 10 also masters the vehicle functions ZV / EDW and KB, which have already been mentioned several times, as indicated schematically here by function blocks.
  • a hand-held transmitter 1 'indicated to the left of the vehicle in turn comprises a signal source 5''whose receivable output power in a suitable manner - as shown above - can be changed via the automatically controllable switching element 3 ′′ in the sense of the sequence in FIG. 1.
  • a receiver 12 is now also provided in the hand transmitter 1 ′, which receives the signals that can be emitted by the transmitter 11 fixed in the vehicle.
  • both the handheld transmitter 1 'and the transmitter-receiver combination in the vehicle F have a transponder function.
