    Status display for the status of an operational component of a
    motor vehicle
    The invention relates to a status display for the state of an operationally relevant component of a motor vehicle. It is essential for the user of a motor vehicle to obtain rapid information about the condition of certain components of the vehicle, such components being considered "operationally relevant" in the context of the invention. be designated. Examples of such states of components are the state of charge of an accumulator battery of an electric or hybrid vehicle or the filling state of a Treibstofftariks, the tire pressure, the engine temperature, etc. Such conditions are usually visible only after the user has taken place in or on the vehicle and usually only after pressing a (ignition) switch.
    From the outside lights are usually recognizable on a motor vehicle, be it headlights, turn signals, brake lights, etc., which are often activated when opening the vehicle by means of a remote control.
    An object of the invention is to make the mentioned states of operationally relevant components of a motor vehicle for a user already visible from the outside, for example when approaching the user to a vehicle, optionally after pressing a remote control.
    To achieve this object, the invention provides that in a status display for the state of an operationally relevant component of a motor vehicle at one of the externally visible position of the vehicle an at least two light sources fed elongated light structure is arranged and the light sources is assigned a drive circuit, which is set up is to control the light sources in dependence of a state signal representative of the state of the operationally relevant component in such a way that the luminance and / or color has long been indicative of the state of the component in the manner of a scale of the luminous structure PI2744 · · ·
    Thanks to the invention, it is also possible using the already existing on the motor vehicle lighting structures to inform the user immediately about certain, especially critical conditions. If, for example, the user is informed that the storage battery of his electric vehicle is empty or almost empty, the user will not even get into his vehicle but will be responsible for charging the battery.
    In an expedient variant, it can be provided that the luminous structure has two or more light sources assigned to the structure, since a large number of practical designs result from the choice of the position and design of the light sources.
    Furthermore, the light-emitting structure may advantageously be designed as a reflector matrix, especially as such a reflector matrix is often an already existing component of a light-emitting unit.
    A particularly expedient variant is characterized in that the luminescent structure is designed as a glowing stick Luminous rods are in fact extremely flexible in their shape and length and thus versatile in use.
    In a further embodiment, it can be provided that each light source has at least one light emitting diode and each light emitting diode is associated with a drive circuit which has a parallel connected to the light emitting diode series connection of a voltage reference voltage and a controlled switch and which is adapted to the control voltage at one all Control circuit common control line, measured against a base of the LED series circuit to compare with the voltage at the connection of the switch with the subsequent LED of the chain or Fußpuhkt and close or open the switch, if the control voltage below a predetermined value falls or rises above a predetermined value. With such a design, the wiring effort for the LED chain is minimal.
    In another variant of the invention, the luminous structure has at least one luminous rod with at least two Lichteinspeisepositionen, each associated with a light source, wherein the light guide is arranged to guide the injected light and for emitting light due to formed on the light guide impurities, and the Drive circuit is adapted to control the light sources at the two Lichteinspeisepositionen the state of the component accordingly. Such a light stick P12744 * ··············································································································································································································· ......... can eg can be easily integrated into existing lighting without degrading the aesthetics.
    In many cases, the display can be made more meaningful if the light sources emit a different color.
    Furthermore, it is often recommended in terms of energy demand and heat generation when the light sources are designed as light-emitting diodes.
    Compact and inexpensive designs can also be obtained if the lighting structure of the status display is arranged in / on a headlamp unit of the motor vehicle.
    The invention together with further advantages is explained in more detail below with reference to exemplary embodiments, which are illustrated in the drawing. In this show

    10 is a schematic view of a luminous bar driven at its two ends;
    11 shows the view of a section of a light guide used in the invention, and FIGS. 12a and 12b show, for example, intensity states of the two light sources at the ends of the light rod of FIG. 10.
    According to FIG. 1, the state of a component 1 relevant for the operation of a motor vehicle, which is not shown here in detail, is detected by an evaluation device 2 which outputs a status signal sz. Component 1 in the present example is the rechargeable battery of an electric or hybrid vehicle, and the evaluation device detects the current state of charge of the battery, wherein the state signal sz indicates the state of charge. However, the component 1 can also be the fuel tank of a vehicle, wherein the evaluation device detects the filling state of the tank. Other status signals could be the coolant / oil temperature of an engine of the vehicle, etc.
    The state signal sz is controlled via a drive circuit 3 to an elongated lighting structure 4, which has at least two light sources 5, 6. The drive circuit is designed to drive the light sources in such a way that, depending on the state of the operational component, e.g. in dependence on the state of charge of the rechargeable battery, the luminance and / or color along the luminous structure 4 in the manner of a scale indicates the state of the component. For example, assume in Fig. 1 at the left end of the light structure 0% (empty battery) and at the right end 100% (full battery), in Fig. 1, an approximately 50% state of charge is assumed, in which the structure 4 from the left beginning to half lit up. Illumination of the luminescent structure 4 can in the simplest case be done with white light or monochromatically, but it is also possible, for example, to produce a green-red transition by using colored light sources, which "turns" depending on the state of the component. Many options for implementing such a light scale are available to the person skilled in the art, examples of which will be explained below.
    The invention further provides that the luminous structure is arranged on an externally visible position of the motor vehicle. The term " visible from the outside " is to be understood, for example, that the status display according to the invention is not, as usual, in PI2744 ··· ···· * · * · · · · (I ··· * ·· * • t * t · "# # * • · »· t · * · I < .................. the dashboard or otherwise within the driver's immediate sight, but on the outside of the vehicle, or anyway Possible examples of an implementation are strips on the outside of a body or an integration in existing vehicle lights, be they headlamps, brake light structures or the like.
    FIGS. 2 and 3 show two exemplary embodiments with regard to the arrangement of status displays in front-mounted headlights according to the invention, wherein in both cases a headlamp unit 7 contains a dimming unit 8 and a high-beam unit 9. Furthermore, a reflector matrix 10 and a glow stick 11 in the headlight, here above the units 8 and 9 are inclined, arranged. The reflector matrix 10 and the luminous bar 11 are e.g. according to design specifications slightly curved or curved.
    The reflector matrix 10, which in the example shown has eleven reflector fields 10a... 10k, each of which can be illuminated by a LED which is not shown in more detail or also each by a plurality of LEDs, is used, for example, as a flashing light, daytime running light, position light. The below the reflector array 10 optionally arranged, dashed lines drawn glow stick 11 can be fed to two or more locations of LEDs and serve, for example, as position light or other purposes.
    In the embodiment according to FIG. 2, the reflector matrix 10 with its eleven reflector fields is also used as a luminous structure for the status display according to the invention. For example, the state of charge of an accumulator battery or the filling state of a fuel tank corresponding to left to right in the sense of a scale more or less reflector fields 10a ... 10k illuminated by their associated light sources. An example of one of many possible drive variants is given below for four light sources.
    4 shows the construction of a light-emitting diode chain for a light-emitting structure according to the invention: a current source 12 supplies a current ILED and supplies by means of the drive circuit 3 in this example four series-connected LEDs LED1 to LED4 against a foot or ground point 13. These four light-emitting diodes For example, a reflector matrix may be * * t * * ·· «t · * · · f ·» * · t • II «« · + I · · · * - 6 * - * ........... similar to the reflector matrix 10 according to FIG. 2, such a matrix having only four reflector fields and not eleven like those according to FIG. 2.
    Each light-emitting diode LED1 .... LED4 is associated with an LED drive AS1 to AS4 which has a series connection, connected in parallel with the associated light-emitting diode, of a reference voltage drop RS of the voltage Uref and of a controlled switch Q.
    A control line 14 common to all LED drives AS1 to AS4 is connected to the output of a ramp generator 15, to which the state signal sz is supplied, and is connected to the control inputs of the controlled switches via a comparison circuit 6 of the LED drives symbolically drawn here. In this case, each LED drive is adapted to a control voltage Ust, which is located on the control line 14, measured against a foot 13, with the voltage UF1 to UF4 at the junction of the switch Q with the subsequent light-emitting diode LD2 of the chain or the foot 13 and to open the switch Q, if the control voltage Ust falls below a predetermined value or to close the switch Q if the control voltage Ust rises above a predetermined value. Overall, with decreasing control voltage, the number of LEDs shining larger. In the symbolic diagram in the block 15 of the ramp generator is therefore shown as an example on the ordinate the control voltage Ust and on the abscissa an increasing state of charge of an accumulator battery.
    The light-emitting diodes LED1... LED4 of the light-emitting diode label do not necessarily have to be a single light-emitting diode; instead of a light-emitting diode, serial and / or parallel circuits of light-emitting diodes may also be provided. A dashed line between the ramp generator 15 and the power source 12 is intended to indicate that optionally an additional control of the current ILED can take place.
    Since all LED controls are identically formed, will be described below with reference to FIG. 5, a field-proven embodiment of an LED driver in detail, which may be associated with the first LED LED1 of the chain.
    Parallel to the LED LED1 is the series connection of two diodes connected in the forward direction, which are denoted overall by Dl and form a reference voltage sink, with the switching path DS of a MOSFET Q, the source S at the cathode of the • • • t «··« ··· · ♦ »» φ 4 · + «···· * ♦ · · * · - 7 · - * ...........
    LED LED1 and its drain D at the cathode of the diode (s) Dl is located. The gate of the transistor Q H lies over the series connection of a protective resistor RI and a separating diode D2 on the control line 14. Source S and gate G of the MOSFET Q are bridged on the one hand by a Zener diode D3 and on the other hand by a resistor R2.
    The isolation diode D2 prevents repercussions on the respective remaining circuits of the light-emitting diode chain and the protective resistor RI in combination with the zener diode D3 prevents harmful high voltages at the gate-source path of the MOSFET. The resistor R2 ensures that the MOSFET switch can be turned off despite the presence of the diode D2. The diode Dl also has the task to compensate for the unavoidable gate-source voltage tolerances of the MOSFET Ql and to take into account the fact that a FET does not have an exact switching point.
    The voltage values given below are merely intended to better explain the function of the invention and depend on the components used and the circuit dimensioning. In the illustrated embodiment, the two, the reference voltage diode Dl forming diodes, for example, Schottky diodes with a typical forward voltage of 0.6 volts, so that the reference voltage Uref the reference voltage Dl is at rated current of the LEDs 1.2 volts. The zener voltage of the zener diode D3 is 8.2 volts, the forward voltage of the diode D2 0.6 volts. The MOSFET Q is typically conducting from a gate-source voltage of 2 volts. The forward voltage of the LEDs is typically 2 volts.
    With further reference to Figures 6 to 8, the function of a four-stage LED array will now be explained, it being understood by those skilled in the art that the invention is by no means limited to a particular number of LEDs and, with appropriate dimensioning, provides more or less than four stages could be. Only two of the four possible states of the light-emitting diode chain are explained below.
    In a first phase according to FIG. 6, the control voltage Ust is 6.5 volts. The voltage at the junction of the switches Q with the subsequent LED of the chain or base is 3.6 volts, 2.4 volts 1.2 volts and 0 volts, respectively. The gate-to-source voltage of each MOSSFET is greater than 2 volts, typically 2.3 volts, 3.5 volts, 4.7 volts, and 5.9 volts for the first through fourth stages, so all MOSFETs Q are duich-controlled and their drain -Source Voltage Lies * · · m · · * «*« »* ·» · ♦ *. 8 · ^ ·· «approximately at 0 volts. At the LEDs LED1 to LED4 is ever a voltage of 1.2 volts, substantially corresponding to the reference voltage Uref. This voltage is well below the forward voltage of the LEDs of 2 volts, it lights no LED. In the diagram of FIG. 9 this corresponds to the starting point of the falling voltage ramp.
    In Fig. 7, the control voltage Ust has dropped to 4.3 volts, the gate-source voltage of the MOSFET of the first stage is only 0.1 volts, that of the MOSFET of the second stage only 1.3 volts, therefore blocks except The switch Q1 of the first stage and the switch of the second stage and the second LED LED1 lights as well as the first LED LED 2nd
    In the phase shown in FIG. 8, all the LEDs LED1 to LED4 light up, since at a control voltage Ust of less than 1.9 volts, the gate-source voltages at the MOSFETs of the individual stages (in the drawing from top to bottom ) now be 0 volts, 0 volts, 0 volts and 1.3 volts.
    Overall, the described mode of operation in the case of a control voltage USt generated, for example, linearly falling, generated by the ramp generator 5, leads to a running, the light-emitting diode chain "filling". Light impression arises For this purpose, reference is again made to Fig. 9a, which demonstrates this operation for a period of 200 ms. As already mentioned, the course of the control voltage can also follow other arbitrary functions instead of a linear function.
    It is understood that a contrary course occurs with increasing control voltage. This is shown in FIG. 9b, wherein the filling state of an accumulator in percent is again plotted on the abscissa.
    Not shown in detail is the possibility already indicated above of controlling the current source 12 to a certain extent by the ramp generator 15 so that further effects can be achieved, e.g. one at "refill" the chain increasing brightness of the LEDs. 9 9 "Φ Φ * 999 ΦΦΦ m. * ·,. • t 9 99 9 »· 9 9 · * - 9- · .......
    The drive option shown has the advantage that, regardless of the number of LEDs used, only three lines are required for the light-emitting diode chain. The simple and cheap drive circuit can be constructed in the smallest space directly at the light emitting diode. Of course, the light emitting diodes may also be directly, i. be controlled without the individual LED controls, if the number of required lines does not play a major role.
    Referring again to Fig. 3, which illustrates an embodiment in which, in connection with the invention, not the reflector matrix 10 is used, but the glow stick 11. In the example shown, this glow stick, which also as a flashing light, has position light and daytime running lights can be used, seven footprints 17a. ... 17g, each footprint at a coupling-in point 18a... 18g as described in more detail below, from a light source, e.g. is lit by one or more LEDs.
    The control of the light sources is carried out analogously by the drive circuit 3, wherein the state of the operationally relevant component corresponding to a more or less long area of the light stick 11 is illuminated in the sense of a scale. Although seven coupling points for seven light sources are shown in FIG. 3, it is possible to achieve a meaningful illumination with only two, preferably dimmable light sources, which radiate at the two ends of a light stick.
    Light sticks are increasingly used in vehicle construction, wherein light, e.g. of light-emitting diodes, is fed at an end face in a light stick. The light is inside the boundary walls of the most circular, but possibly also another, e.g. elliptical or rectangular cross-section optical fiber totally reflected, but at the impurities, e.g. are formed prismatic, abgereikt and radiated essentially at the opposite side of the impurity. An example of such an optical waveguide structure has become known from EP 0 935 091 A1. This document is a rod-shaped optical fiber, in which provided to achieve a uniform luminance over the entire length provided as impurities Iichtablenkende prisms have a width transverse to the rod axis, starting from the Lichteinkoppelfläche starting, and an embodiment is described in which an both ends of the PI2744 # ···· · · · · · · · ft ··· ftftft »· -10 * • ft Φ ··· *
    Light guide a light input surface and, accordingly, two light sources are provided.
    10 is a lightly curved optical fiber having at each of its two ends at a light feeding position A and B a light source 5 and 6, respectively, which can irradiate light into a light entrance surface 5A, 6A. Each of the two light sources 5, 6 is fed via supply lines 5s, 6s from the drive circuit 3, to which the state signal sz is supplied. Preferred light sources are LEDs, but other light sources, such as incandescent lamps, xenon lamps, etc. may also be used.
    FIG. 11 shows an enlarged section of the glowing stick 11, on which a structure of defects 19 can be seen. In this case, the impurities formed as prisms each have two areas of light surfaces, namely each surface of light surfaces 20 and light surfaces 21. This makes it possible that light supplied from both sides of the luminescent rod is actually emitted, essentially at the side opposite the impurity structure side of the luminescent rod.
    The light sources used in the invention need not radiate white light or be monochromatic, but also light sources with variable colors (RGB light sources) can be used. It is possible, for example, to produce a color transition from red to green.
    Reference is now made to Figs. 12a and 12b, which show in diagrams possible states of the predetermined by the control circuit 3 intensity of the light sources 5 and 6 at the feed positions A and B, wherein the curves shown can also be referred to as dimming curves.
    The intensity LA of the first light source 5 at the position A, for example, starts from a certain maximum value, which can be arbitrarily defined. This is followed by a falling dimming ramp, this being shown as an example linear, but for all the dimming ramps described here other waveforms are possible whose course depends on the state change of the component. Here, the intensity of the light source at the position A decreases to a minimum value, and then, according to a rising dimming ramp, P12744 ········································································. .... to increase linearly here. At the end of the rising dimming ramp, the light source 5 at position A has again reached maximum brightness
    Looking at the intensity profile of the second light source 6 at the position B, it can be seen that in this example, the second light source is controlled so that the brightness curve is exactly opposite to that of the first light source 5 at the position A. This type of driving makes sense with light sources of different colors, since this produces the effect of light traveling from position A (e.g., green) from the light from position B (e.g., red). Assuming these colors of the two light sources shines in a first state range Bl the light stick in the color green, d. H. an observer would-in the example of an accumulator battery-be shown a full charge state thereof. In the state area B2, on the other hand, the glowing stick would be lit in red, and a viewer would be notified that the state of charge is zero. Between these extreme ranges, the proportion of the luminous area or length is indicated by the ratio of the intensities of the two light sources 5, 6 at points A, B, corresponding to intermediate states of the state of charge of an accumulator battery in this example.
    When a specific number of light sources are described and illustrated in the examples shown, it should be clear to those skilled in the art that these figures are by no means limitative. For example, the embodiment according to FIGS. 4 to 8 can have a larger number of light-emitting diodes than four. Also, the lighting structure by no means must be imperatively elongated, but it also come light structures with other geometry, such as rings, circles with illuminated sectors, etc. in question.
