Abstract

A portable remote control unit has a switch (2) by means of which a display unit (3) and a transmitting unit (4) are controlled, depending on the duration of the operation. With an operation which lasts for a short period, the display unit (3) is switched over so that a new control state is displayed. With an operation which lasts for a long period, a control signal allocated to the displayed control state is transmitted. In this way, several functions can be remotely controlled with only one switch (2).

Description

is 2333388 ORTA13LE REMOTE CONTROL UNIT AND METHOD FOR OPERATING THE
REMOTE CONTROL UNIT The invention relates to a remote control unit and to a method for operating the remote control unit. The invention particularly relates to a remote control unit for an antitheft system of a motor vehicle, and the associated method. A central locking system of a motor vehicle can be remotely controlled with such a remote control unit.
A remote control unit disclosed in DE 43 29 697 C2 has a computing unit which emits a control signal upon the operation of a switch. Door locks of a motor vehicle are locked or unlocked with this control signal. However, with a remote control unit of this kind, different units such as individual doors or other devices in the motor vehicle can only be remotely controlled if there is a specific switch for this purpose for every control command.
The invention seeks to create a portable remote control unit which is assembled with as little expenditure as possible and with which several different remote control functions are to be carried out.
According to one aspect of the present invention, there is provided portable remote control unit having a manual switch unit; an optical display unit; a control unit, which controls the optical display unit to display a control state of an object to be remotely controlled, wherein upon operation of the manual switch unit for a duration lying within a first duration range, the control unit changes the control state and displays on the display unit the new control state, and upon operation of the manual switch unit for a duration lying within a second duration range the control unit generates a control signal corresponding to the displayed control state; and a transmitting unit which transmits the control signal wirelessly.
Thus, in accordance with the invention, the remote control unit has only a single switch unit which is operated for the remote control of an object. Depending on the duration of the operation, the control state of the object is indicated and corresponding control signals are emitted. In this way, a small remote control unit can be created, which can be easily transported by a user and which is less susceptible to faults.
Advantageous developments of the invention are set out in the subclaims. In this way, a display unit can consist of several light-emitting diodes (LED) which can differ in colour and/or shape. The switch unit is advantageously constructed in a simple manner as a pushbutton. The remote control unit can therefore be arranged on a small easily transportable card, for example a card the size of a cheque card, or on a handle of a mechanical key. The remote control unit can also have a receiver which receives check-back signals from the object to be controlled and can therefore correctly display the control state actually set.
For a better understanding of the present invention, and to show how it may be brought into effect, reference will now be made, by way of example, to the accompanying drawings, in which:
Figure 1 shows a block diagram of a remote control unit in accordance with the invention.
Figures 2 to 4 show flow charts of different methods for operating the remote control unit.
The portable remote control unit of the present is invention will now be described in relation to a remotely controllable central locking system (keyless access control) of a motor vehicle. In this respect, upon request the remote control unit transmits a code signal to a receiver in the motor vehicle. The code signal is tested there for its authorization (authentication). With successful authentication, door locks are unlocked and/or an immobilizer is released. The method of authentication by means of a questionresponse-dialogue is already adequately known and described in more detail in Patent Specification DE 43 29 697 C2 already mentioned above. Reference is hereby made to the description of the authentication.
With the remote control unit in accordance with the invention, in addition to the authentication with the code signal, additional remote control functions can also be carried out. For this purpose, as shown in Figure 1, there is provided a control unit (also called microprocessor I in the following description) with which the functional sequence of the remote control unit is controlled. The microprocessor 1 is connected to a switch unit (called switch 2 in the following). Upon the operation of the switch 2, the microprocessor 1 is activated depending on the duration of the operation, i.e. a program run is started.
Moreover, the microprocessor 1 is connected to an optical display unit 3, by means of which a control state (or also called circuit state) of an object to be controlled is represented. The object or objects is or are controlled by control signals which are generated by the microprocessor 1 and are transmitted by way of a transmitting unit 4 and by way of an aerial 5. All units of the remote control unit are supplied with current and voltage by a voltage source 6.
The control signals in this embodiment of the invention are binary coded signals which are is transmitted together with the code signal to the object. By examining the code signal for its authorization it is ensured that only an authorized user can remotely control a function in an object.
A method for operating the remote control unit will be explained in more detail with reference to the flow charts of Figures 2 to 4.
In accordance with the method shown in Figure 2, as soon as the switch 2 shown in Figure 1 is operated, the display unit 3 is activated. In this way, the user can see which state the object to be controlled has occupied, i.e. which control commands were last transmitted to the object or which control state was signalled back by the object.
If the switch 2 is no longer operated, the display unit 3 is deactivated immediately or after a specified duration, in order to save energy.
If the switch 2 is operated briefly during the display duration (more brief ly than a threshold value or a specified duration), the display of the display unit 3 is changed. Each different display of the display unit 3 corresponds to a control state of the object to be controlled. By means of a repeated, brief operation of the switch 2 the user can cause the display unit 3 to display a desired control state.
Each control state is also allocated a control signal which, however, is only transmitted if necessary. If the switch 2 is operated during the display of a control state for a prolonged duration (longer than the threshold value or the specified duration), the control signal allocated to this control state is generated in the microprocessor 1 and is transmitted by way of the transmitting unit 4 and the aerial 5. Thereupon, a remote control function corresponding to the control signal is performed in the object, after which the authorization is examined with the aid of the code signal and the content of the control signal is recognized.
The display unit 3 can consist, for example, of two LEDs which light up in the colours red and green. If, for example, door locks of the motor vehicle are to be remotely controlled as the object, the following control states can be displayed by the two LEDs. If only the green LED lights up, "all door locks are unlocked". If, on the other hand, only the red LED lights up, "all door locks are locked". If both LEDs light up simultaneously, "only the driver's door is unlocked". If no LED lights up, the display unit is not activated. The display duration corresponds to the time during which one of the LEDs is lit up.
There can also be additional LEDs which display additional control states. Therefore, for example, it can be shown whether the boot is locked or unlocked or whether the windows are open or closed.
With brief operation of the switch 2 (operation lasts, for example, less than a threshold value of 0.5s) the display unit 3 according to Figure 3 is switched on if it was previously not activated. The LEDs light up for a specified period (display duration for example 2s long) if, during the period in which the LEDs are lit up, the switch 2 is operated briefly again (more briefly than a threshold value of 0. 5s), the next control state is displayed. The display unit 3 is activated for a specified duration (display duration at least about 2s).
If, during the lit-up period/display period of the LEDs, the switch 2 is pressed for a long time (longer than a threshold value of about is), a control signal allocated to the currently displayed control state is generated in the microprocessor 1 and is transmitted. Thereupon the LEDs can go out.
As soon as the switch 2 according to Figure 4 is operated more briefly than a first duration x, the display unit 3 is activated in order to display the hitherto-existing circuit state or control state. In this way, the user can see which state the object to be controlled has occupied, i.e. which control commands were last transmitted to the object or which control state was signalled back by the object.
If the switch 2 is operated for longer than the duration x, it is inquired whether the switch 2 is operated longer than a second, specified duration y. If the switch 2 is operated for longer than the duration x, but more briefly than the duration y, the next circuit state or control state is displayed in the display unit 3.
If the switch 2 is operated both longer than the duration x and longer than the duration y, in the microprocessor 1 the control signal allocated to this last control state is generated and transmitted by way of the transmitting unit 4 and the aerial 5. Thereupon, a remote control function corresponding to the control signal is performed in the object, after which the authorization is examined with the aid of the code signal and the content of the control signal is recognized.
with a prolonged operation of the button, either a control signal can be emitted, which corresponds to the control state just displayed (that is to say the circuit state last displayed) or also to the next, subsequent control state. If, for example, the control state "motor vehicle locked" is displayed,,lock motor vehicle,, can be emitted as control signal. However, the next control state can also be emitted, so that the cont rol signal "unlock motor vehicle" is transmitted when "motor vehicle locke& is just displayed. With regard to the central locking system, the following control states can be occupied, for example: "motor is vehicle locked", "driver's door unlocked", "all doors unlocked", "boot unlocke& and "all doors locked".
With the remote control unit in accordance with the invention, individual control states can be selected and control signals allocated to these control states can be transmitted. By means of the display unit 3 the user obtains a check-back signal as to the control state of an object, such as the central locking system of the motor vehicle, i.e. which control state was the last to be emitted by the remote control unit.
With this remote control unit, not only can door locks of the motor vehicle be controlled, but so can other objects which can be electrically remotely controlled, such as window winders, sun-roof, hood, seats, mirrors, air-conditioning equipment or heating in the motor vehicle. In addition, objects outside the motor vehicle, such as garage door or the illumination of buildings, can also be remotely controlled. A respective different control signal is allocated to each object and the associated remote control function (such as locking or unlocking), so that an object is also correctly remotely controlled as desired.
The switch 2 can be constructed as a pushbutton, where the duration of operation corresponds to the time during which a button is depressed. The switch 2 can also be constructed as a capacitive switch 2, where the duration of the operation corresponds to the time during which the switch 2 is contacted. A slide switch can also be used as switch 2. The formation of the switch 2 is unimportant for the invention. On the other hand, it is important that different displays or control signals are initiated by the microprocessor 1 depending on the duration of operation.
The remote control unit can also have a receiving unit which, together with the transmitting unit 4, forms a common transmitting and receiving unit. The receiving unit can have its own aerial which is independent of the aerial 5. Likewise, the aerial 5 of the transmitting unit 4 can be used as receiving aerial.
The receiving unit can receive a check-back signal from the object to be controlled. The object can thereby signal its actually occupied control state back to the remote control unit. This control state can then be displayed by the display unit 3. In this way, the user can check whether the control state which they desire and which is set is also actually occupied by the object which is to be remotely controlled.
The transmission of signals between the remote control unit and the object to be controlled takes place wirelessly, i.e. by radio, optically or acoustically. If the signals are transmitted by radio, they can be transmitted at high frequency or at low frequency (for example inductively). With inductive transmission the aerial 5 is constructed as a coil which is then used both as transmitting aerial and as receiving aerial. With optical transmission an IR light-emitting diode is constructed as transmitting aerial and an IR photodiode is constructed as receiving aerial. With acoustic transmission an ultrasound transmitter is constructed as transmitting aerial and an ultrasound receiver is constructed as receiving aerial.
The remote control unit is preferably constructed on a card the size of a cheque card (chip card or socalled Smart Card). However, the remote control unit can also be constructed on a key handle of a conventional mechanical door key or ignition key or a functionally equivalent device.
only a single button can be used for controlling the different functions of an object, and otherwise few components are arranged on the remote control unit, and so the dimensions of the remote control unit are very small. In addition, the switch 2 can be constructed to be very small in the form of a micromechanical switch 2. The display unit 3 also requires little space. Instead of the microprocessor 1, another, functionally equivalent logic circuit integrated on a semiconductor chip can also be used.
is The voltage source 6 can be constructed as a battery or as a rechargeable battery. Likewise, a capacitor is possible as voltage source 6, which is charged by received power signals. The voltage source 6 therefore does not need to be replaced if the power supply runs low.
The remote control unit can also have several switches 2, with one of the switches 2 being constructed as menu switch and the other as functional switch. With the menu switch the object to be controlled is selected and with the functional switch the corresponding remote control function is selected, to which a corresponding control signal is then to be transmitted.
By means of brief operation of the menu switch and the functional switch the object and the remote control function are selected. By means of prolonged operation of the functional switch during the display period a control signal allocated to the selected control signal is generated and transmitted.
In this case an LCD display is advantageously used as display unit 3. In this display the object and the remote control function can be displayed by means of text. Therefore the user does not have to know the meaning of LEDs which are lit up, but can directly read the remote control function which has just been set.
The remote control unit can also be used as means for authentication for releasing an immobilizer.
However, the remote control unit then behaves passively (like a transponder). with the operation of the ignition switch a request signal (challenge) is transmitted to the remote control unit, which thereupon responds with a response signal (response). A display on the remote control unit with respect to the control state of the immobilizer (whether the immobilizer is released or not) is not necessary. The switch 2 needs to be operated just as little because the ignition switch is operated in order to start the motor vehicle.
