Definitions

  • the invention is based on the method defined in the preamble of claim 1.
  • the invention is therefore based on the fact that it is known to clock the power supply of the receiver of a motor vehicle locking system in order to save electricity during parking, that is to say during waiting times, and thus to conserve the energy stored in the motor vehicle's battery.
  • a main problem of such methods is the avoidance of deep discharges of the battery if the vehicle is parked for a long time and the locking system is not operated. During this waiting period, the receiver may receive many different control signals, but none that the locking system has to operate. It may happen that the receiver receives many control signals during this waiting time, but these are intended for other motor vehicles, whereas the control signal intended for this motor vehicle is sometimes only received after a week and even later.
  • FIG. 1 thus shows a person who sends out control signals C coded with the hand transmitter H in order to actuate the locking system installed in the motor vehicle K.
  • the handheld transmitter H sends e.g. Infrared light control signals C or radio control signals C off.
  • the locking system contains the receiver E, also shown in FIG. 2, which receives the control signals C via its antenna (here symbolically indicated by D) and evaluates whether the code of the control signal C indicates that the sending person is authorized to operate the locking system is or not. Depending on the receiver E then emits an actuation signal G which actuates the closures of the motor vehicle K or not.
  • the power supply, cf. the battery B of the motor vehicle K is continuously used by the receiver E when the motor vehicle is parked, especially if the waiting times are very long, perhaps weeks.
  • a main problem of such power supplies is then the avoidance of deep discharges of the battery B, which not only has to supply the receiver E with power during the waiting times and finally when entering the vehicle, i.e. opening the doors, but above all when the next start Motors has to supply the starter with electricity.
  • the invention at least largely avoids deep discharge during the waiting times by clocking the power supply of the receiver E in a special way.
  • clocking the power supply B By clocking the power supply B, the energy consumption of the receiver E is considerably reduced.
  • FIG. 2 shows the operating switch A, which is clocked for this purpose during waiting times and switches the power supply B alternately ON and OFF, of the receiver E which can be remotely controlled by a hand transmitter H with the control signals C clocked, the clock pulses Q are separated by more or less long clock pauses P.
  • a number of successive waiting times are distinguished in the invention.
  • the power consumption of the receiver E may be relatively high, as a result of which the receiver E is then always quickly ready to actuate the locking system immediately when it receives authorized control signals C.
  • the operating switch A with a comparatively long cycle pauses P between the ON circuits is activated during a subsequent second waiting period Q of the power supply B operated clocked.
  • the clock pauses P are longer during the second waiting time than during the first waiting time.
  • they are, for example, 100 msec or 2 seconds each.
  • the receiver E is only supplied with current for a short time, namely with the time after increased pauses P.
  • the invention thus largely avoids deep discharges of the battery B by noticeably reducing the power consumption of the receiver from the second waiting time.
  • the cycle pauses P in the first waiting time can be made negligible. Then you operate the operating switch A so that it constantly supplies the receiver E with power during the first waiting time, but in the subsequent second waiting time with finely long clock pauses P between the switch-on phases Q. In this case, the operating switch A is only from the operated second clocked cycle, whereby the receiver E is always immediately ready to evaluate received control signals C during the first waiting period and accordingly to immediately operate the locking system.
  • the length of the clock pauses P can be even longer than during the second during further waiting times after the second waiting time Waiting time can be selected. Then the pauses P continue to increase over time and thus the power consumption continues to decrease over time. You can, for example, make the pause duration 5 seconds and even longer.
  • the coded control signals C can be repeatedly emitted from the hand transmitter H repeatedly, even if the trigger on the hand transmitter H is actuated only once, over a longer transmission period. It is then advantageous to make the duration of the clock pauses P shorter than the duration of the transmission. If the receiver E receives signal fractions during its short ON phase Q, the receiver E is temporarily connected to the battery B via the operating switch A at least for the entire duration of the reception of a complete code, so that the receiver E can now check the authorization of the received code .
  • Another development of the invention allows the power-saving clocked operation to be able to continue undisturbed, even if the receiver E of the parked motor vehicle K has control signals C. receives, which each contain only an unauthorized code, because they are actually only intended for other vehicles, i.e. should operate the locking systems of other vehicles.
  • the clock frequency QQQ of the actuation of the operating switch A can be made at least approximately the same size as it would have been without the reception of this control signal C. It is then avoided that the receipt of an unauthorized code immediately triggers the beginning of the first waiting time and thus again a period with high power consumption.
  • the clock frequency QQQ of the operation switch A again during the subsequent first waiting time correspond to the usual power supply method.
  • the first waiting time can only be started again when the motor vehicle battery is recharged.
  • the clock frequency QQQ of the actuation of the operating switch A can only correspond to the clock frequency QQQ of such actuations occurring during the first waiting time if the motor of the Vehicle was started.
  • a deep discharge of battery B can be avoided with even greater reliability by not letting the first waiting period begin again until the battery of the motor vehicle has been sufficiently recharged.
  • the voltage can at least occasionally of the battery B can be measured, the pause time P being determined as a function of the measured voltage of the battery B.
  • the clock frequency QQQ of the actuation of the operating switch A is not always the same during the first waiting time, that is to say immediately when parking begins. Instead, this clock frequency also depends on the current state of charge of the battery B, for example by using a power supply mode immediately after parking that corresponds to the second or an even later waiting time - the clock frequency QQQ then possibly reducing even further in later waiting times can be.
  • the locking system installed in the motor vehicle K - e.g. also directly in the housing of the receiver E - contain a clock F, which should operate the operating switch A clocked during the relevant waiting times.
  • the clock F e.g. can contain or represent a flip-flop.
  • the clock can, e.g. also an electronic counter, a clock or the like. be.
  • the subsequent reduction in the clock frequency Q-Q-Q that is to say the subsequent extension of the pauses P, can also be achieved in that the clock generator F contains an electronic frequency reducer.
  • the clock generator F can contain a storage capacitor which, at least until the next actuation of the operating switch A, requires operating energy to operate the clock generator F saves. So you can have your own permanent direct power supply I of the clock F avoid, cf. the direct power supply I of the clock generator F indicated by dashed lines in FIG. 2. Instead, the power supply of the clock generator F can then also take place via the operating switch A.
