Definitions

  • the present invention relates to a control means for a parking heater of a motor vehicle.
  • Firmly built-in parking heaters in motor vehicles have been Jcnown for more than two decades.
  • Such parking heaters are heating systems which are independent of engine operation, yet are nevertheless connected with the engine and its cooling system.
  • these heaters are connected with the coolant circuit of the motor vehicle.
  • the coolant is heated by a heat source, which is independent of the combustion engine, to such an extent that both the engine block is warmed, and the passenger compartment can be preheated by the heating system already provided, if necessary by additionally using an electric fan.
  • Said control means comprise an electronic circuit which activates the parking heater either via a wireless remote control or a timer or a combination thereof.
  • the wireless remote control comprises a hand-held unit (transmitter) and a receiver unit which is connected with the control means.
  • the hand-held unit (transmitter) can send a starting impulse using the centimetre band or other high- frequency ranges or infrared light to the receiver unit which in turn activates the parking heater, thus heating the engine and the passenger compartment.
  • the heater can also be started via a timer which is a part of a unit together with the receiver and/or the control means which is firmly installed in the vehicle.
  • the timer with a digital or analog display of the current time and adjustment elements, is firmly mounted on the dashboard of the vehicle, and it is only from there that the driver can adjust the starting time of the heater.
  • This adjustment is either carried out in the vehicle for a later point in time every time the vehicle is parked, or by a sequence of program instructions of the control means in the vehicle.
  • the heater may also be activated by a remote-control impulse, independently of the already adjusted timing.
  • the timer which is firmly installed in the vehicle has to be adjusted at a certain time, which may be about 1.5 hours before starting the vehicle.
  • the object of the present invention to further enhance ease of operation in the narrow field of parking heater control although the technology available has already contributed to a very high standard thereof.
  • This object is performed by the present invention in that for the above-mentioned kind of parking heater controlled by means of a timer and a hand-held unit with actuation ele ⁇ ments, the hand-held unit (transmitter) is provided with an electronic clock, whose time appears in a display of the hand ⁇ held unit, said hand-held unit being provided with a programm ⁇ able timing element and elements for inputting the heater (de-)actuation times.
  • the relocation of the clock unit from the vehicle dashboard to the hand-held unit (transmitter) does not present any problems since conventional clock and time program modules are used, i.e. the size and current consumption of the hand-held trans ⁇ mitter unit hardly change at all, and considerable advantages are obtained in this way.
  • the present invention enables the driver to ad ⁇ just or change the heating time via the hand-held unit without having to actually go to the vehicle.
  • the driver's time schedule changes, he can change the current adjustment of the heating period of the parking heater by simply changing the adjustment in the hand-held unit. If, for example, a sud ⁇ den change of the weather results in an increase or decrease of temperature, the heating period may conveniently be reduced or extended via the hand-held unit.
  • An additional clock unit with a display and clock control is superfluous in the vehicle since the driver can secure the hand-held unit to the inside of the vehicle, in a suitable support, so positioned that the driver can still read the display in the hand-held unit.
  • the wireless connection to the control means is of course maintained in the short distance in the vehicle.
  • the actual time display in the hand ⁇ held unit eliminates the need for providing an additional clock in the vehicle. Further details, features and advantages of the invention may be gathered from the following description of an embodiment example shown in the drawing.
  • Fig. 1 is a block scheme of the structure of a novel remote control device for the control means of a parking heater
  • Fig. 2 is a schematic, perspective view of a hand-held transmitter unit.
  • a conventional parking heater 12 is mounted in a vehicle, which is shown in Fig. 1 having the reference numeral 10, a conventional parking heater 12 is mounted.
  • the parking heater 12 is connected with a control means 14 which represents an electronic circuit and controls all the func ⁇ tions of the heater 12.
  • the control means 14 can preferably also be switched on or off via an emergency switch 16 in the vehicle itself. In normal operation, however, the control means is activated via a decoder 18, which is connected with a receiver 20.
  • the receiver 20 responds to wirelessly transmit ⁇ ted signals emitted by a transmitter 22 in a hand-held unit 30.
  • the hand-held transmitter 30 is schematically shown in perspective in Fig. 2.
  • the hand-held unit 30 is provided with a set of adjustment buttons, of which for example one button 34 "start” causes the direct activation of the heater 12 via the control means 14 in the vehicle 10.
  • the desir ⁇ ed switch-on or switch-off time can be adjusted which is shown in the display 32.
  • the times to be adjusted may be incremented or decremented by means of the two (+) and (-) buttons 38, 40 resp. , when the actuation button 36 is pressed at the same time. This is done by means of an incrementor and decrementor 28 situated in the hand-held unit (Fig. 1) .
  • the corresponding counting pulses are used either for adjusting the real time of the clock or for adjusting the switch-on and -off times, for which latter pur ⁇ pose a module 42 is provided in the hand-held unit 30.
  • module 42 there is another module 44 for normal start.
  • the modules 42 and 44 control an encoder 46 whose output signals are input to the display 32 and the transmitter 22.
  • buttons 48 may be provided in the keyboard of the hand-held unit 30.
  • the transmitter 22 is adapted for high-frequency operation and - in the absence of any obstacles - has a range of approx. 2000 m, when operated in the centimetre band, whereas in built-up city areas its maximum range is about 500 m.
  • the hand-held unit 30 also includes a possibility to release a so-called booster start.
  • a booster 50 is provided which sends a pulse sequence from the transmitter 22 to the receiver 20, said pulse sequence differing from the normal start signal which is initiated via button 34.
  • the receiver releases an output actuation signal to the heater 12 via the control means 14.
  • the operation time is substantially shorter and the different pulse sequence causes the control means 14 to increase heat output to the passenger compartment, for example by increased fuel flow to the heater 12 or increased speed of the passenger compartment fan or an adjustment of the connection of the coolant circuit with the heater 12, so that heat exchange into the passenger compart ⁇ ment is increased.
  • the control means is then ready for a new starting cycle.
  • the hand-held transmitter unit 30 then emits a signal to the receiver (dependent on a program stored in a program memory 52 in the hand-held unit 30) .
  • the program starts the heater and also stops it if a corresponding stopping time has also been programmed.
  • the timer has to be of the kind which allows the programming of several time moments which might be stored and released in chronological order.
  • the above-mentioned actuation elements 34, 36, 38 and 48 can be used and the program entered and stored in the memory 52 can be run or changed any time independent of other activation and operation modes.
  • Parking heaters on the market today are thermostat-controlled for saving energy and also use internal and external temperature sensors.
  • Said temperature sensors constantly supply data to the control means 14 which then form the basis for the operation mode of the system.
  • the heating-up times and the heating intensity can thus be varied and consequently adapted to external conditions. This may for example be effected using a so-called delayed start of the fan directed into the passenger compartment, and an external temperature sensor also determines the starting time of the heater.
  • the heater is always aimed at keeping the coolant temperature as high as possible by increasing and decreasing the heating effect without the heater operating periodically. It is preferred to pulse the fan for saving electric energy and providing a possibility of controlling the speed of the fan.
  • the control procedure is based on a serial cycle in which during the first heating period the engine alone receives all the heat generated.
  • the heater operates for 1.5 hours (operation time depending on the external temperature) the engine alone is heated for 50 minutes and the passenger compartment for 40 minutes.
  • the heater is started directly, the maximum effect thereof, which corresponds to a power output of about 5.5 kW, has to be developed together with another, higher pulsing of the passenger compartment fan. Under said conditions, the heater has to operate for only about 20 minutes. This is a rapid heating action which is required when a sudden need for a ready-heated vehicle occurs.
  • the receiver unit 20 has been illustrated as mounted separate from the control means 14 of the heater 12 but of course, said receiver unit 20, the decoder 18 and the control means 14 might be integrated in one unit, with only the antenna and an external temperature sensor protruding therefrom.
  • the hand-held unit 30 containing the transmitter 22 has been designed for easy handling and operation. There should be as few actuation buttons as possible which are to be light- emitting or illuminated in darkness. In a known manner, the actuation buttons can be combined with each other by simultaneous pressing thereof such that overlapping functions may be exploited, in particular when a (+) 38 and a (-) button 40 can be used. In this case, the heater 12 can be started immediately when only the start button 34 is pressed but it is also possible to store 1-15 timer-controlled starts.
  • the heater starts directly at maximum power.
  • the passenger compartment fan is now pulsed with high frequency.
  • the control means 14 receives two output signals from the transmitter unit 22 via the receiver 20 and the decoder 18, said signals corresponding to immediate start and operation at maximum power for 20 minutes.
  • the display window 32 indicates normal time while in the lower portion thereof operation time lapsed is indicated.
  • starts for the working days from Monday to Friday should be input by providing the corresponding order by pressing the (+) button 38 and storing thereof in the memory 52.
  • the correspondingly stored operating states can be shown in the display by means of short symbols.
  • the display can be a day of the week or a date. What is displayed is always the next start stored, which has not yet been carried out.
  • Pressing the (-) button 40 makes the timer ready to be adjusted to desired time by pressing several buttons at a time, for example the (+) 38 and (-) buttons 40, respectively.
  • the adjustment made is confirmed by pressing the timer button 36.
  • a further press on the (+) button 38 will make the timer clock advance exactly 24 hours. This time in turn is confirmed in the memory 52 by pressing the timer button 36.
  • the transmitter When timed, the transmitter always emits a signal to the receiver unit 20 and the control means 1.5 hours before the vehicle is to be ready-heated for its use.
  • An external temperature sensor will reduce this time if the external temperature has changed by a certain amount compared to the temperature at the time when the adjustment was made.
  • an internal temperature sensor can stop or reduce the heating period when the desired internal temperature of the passenger compartment has been reached earlier than expected.
  • a small additional transmitter 60 next to the receiver 20 can transmit feedback signals to the hand-held unit 30, in which a receiver 62 is mounted. By means of a decoder 64, said receiver 62 renders operating states visible in the display. In this manner, it is equally possible to display the values measured by an internal temperature sensor 66 and those determined by an external temperature sensor 68. This is an additional embodiment which would further improve convenient use of the device according to the invention and at the same time indicate the situation in the vehicle to its user.
  • the hand-held transmitter unit 30 must be switched on via the switch 26.
