It is an object of the present invention to provide a display unit for data depending on the energy consumption of a vehicle, which clearly displays the most important data depending on the energy consumption and the energy tank capacity.

The problem is solved by the features of claim 1 in accordance with the invention. The display unit according to the invention is equipped with a reach indicator, which gives the driver an area of expected reach, for example in kilometers (Km). In the first embodiment of the display unit, the area of reach depends on the amount of energy present in the energy storage system and the minimum and maximum average consumption of the vehicle engine in relation to the vehicle-specific parameters.

The driver's specificity is also taken into account in the area of reach displayed in the second embodiment of the display unit according to the invention. The uniqueness of this driver may be, for example, a sporty or economical way of driving. For example, at a predetermined percentage, for example 50-75%, the area of reach given to the vehicle-specific average consumption is limited in the area of average consumption in which the driver's behavior is fully taken into account and calculated by experience. In the reach ranges given thereupon, further limitations are possible in which the behavior of the driver in close contact with the vehicle is measured and used. In this data the minimum and average consumption is used in the calculation of the reach area. The reach range displayed is also narrower.

The vehicle's reach indicator can omit the indication of the amount of energy in the storage system or energy tank, identify the existing amount of stored energy that depends on the vehicle's consumption in the range of reach indicated by the driver, and There is an advantage of the two above embodiments in being able to operate in a state.

It is also advantageous that the graduation device reached is omitted in the changing operating conditions or changing operating conditions, and the indication of this area therein includes this changeable parameter. As in the case of a rental car, the vehicle is driven by different drivers, who then know the engine's consumption and the total amount of fuel tanks for the driver at that time, and can immediately recognize it by calculating the maximum at any reach.

The indication of the minimum or maximum reach is configured as an indicator with two indicator needles accessible independently of one another in an advantageous embodiment. In this advantageous embodiment, the display of the reach area consists of a bar-shaped display device with a highlighted area, wherein the highlighted part is configurable as a colored and / or lighting device. In a third advantageous embodiment, a digital display is provided, in which the display of the reach area is also spaced from each other and in the form of numbers.

In an advantageous embodiment, the scale of reach is divided on a larger scale from the storage amount area so that the driver can accurately determine the reachable area. Another advantage is that the scale of the reach is small or narrowly divided in the upper region of the energy tank, which is still relatively high in energy. The energy storage amount may be displayed by changing the display color, and the dedicated storage amount lamp may be omitted.

In an advantageous embodiment the interior of the reach area highlighted or displayed is designed to visually identify the expected reach in the current or actual way of travel.

In this advantageous embodiment of the display unit it is noticeable that the given reach range is limited or reduced at constant or varying percentages. In an embodiment that does not take up much space, the upper region of the scale of reach is cut off, in particular the reach relates to a particularly economic way of travel. That is, the maximum reach starts at the mean or median.

In the display unit according to the present invention, it is an advantage of the present invention that, for the appropriate software, the threshold of the average average consumption can be changed during driving. When it is confirmed that the threshold value calculated by experience in the apparatus for using the display unit according to the present invention is exceeded or falls short of it, the reduced reach area is expanded there and the threshold value is adjusted.

In this or more embodiments, the amount of energy present in the energy storage tank in addition to the reach may be displayed or recalled.

Embodiment of this invention is described based on an Example based on the following drawings.

1A, 1B and 1C show a display device 1 which is configured as a needle gauge 2 with two display needles 3 and 4, respectively. The needle gauge 2 presents a scale 5 of linear reach. The needle gauge 2 is composed of a circular gauge. The indication needles 3 and 4 are adjacent to each other separately and can be moved separately from each other.

1A relates to the reach range in the amount of energy storage. Clearly in Fig. 1, the two indicator needles 3 and 4 are arranged relatively narrowly side by side depending on the few reach areas.

FIG. 1B shows the reach area corresponding to a half filled state of the storage system or energy tank. The two indicator needles 3 and 4 are separated by a relatively high amount of energy as compared to the position in Fig. 1A.

The area of reach shown in FIG. 1C is limited. As shown in FIGS. 1A and 1B, the display needle 3 displays a minimum reach. However, unlike in Figs. 1A and 1B, the display needle 4 displays the reach, not the maximum reach. This reach can be set to an empirical value, for example, a median.

2A, 2B and 2C relate to the display device 1 made of the bar display device 6. This bar display 6 presents a scale 7 of linear reach, if necessary. The reach area is represented by a bar 8 which is visually highlighted. This emphasis is indicated, for example, by the illumination of the reach area resulting from the amount of energy present. As with the indicator 2 the scale 7 of the reach ends at the bottom of the maximum possible reach. In addition, the bar 8 on the left boundary line 9 indicates the minimum reach as shown by the display needle 3. In Figs. 2A and 2B only the right limit line 10 indicates the maximum reach distance. In FIG. 2C, the right limit line 10 only moves toward the left limit line 9. Comparing the rod of FIG. 2B to the rod of FIG. 2A, it can be clearly seen that the rod 8 is elongated corresponding to a half filled energy tank, whereas the rod 8 is short corresponding to a small amount of energy. By doing so, a boundary that is larger than the possible reach simply becomes apparent.

FIG. 3 shows a bar display device 11 similar to the bar display device 6 of FIGS. 2A, 2B and 2C, with one bar 12 of the bar display device 11 indicating the area of reach. It has a window 13, which displays the estimated reach in the actual driving state. The bar 12 also presents a left limit line 14 and a right limit line 15, which represent the minimum and maximum reach distances.

In FIG. 4, the bar display device 26 is represented, where the distance scale 27 is nonlinearly divided between the lower region 28, for example, 0 Km and 300 km. Through the extension of the lower region 28 and the reduction of the rod 30 displayed in the reach region 29, the remaining reach is relatively narrowly limited. Unlike the beam-type display of Fig. 3, the scale of reach 27 presents the highest value at the end 32, which is limited in the upper region, which means that a reach greater than 600 in a properly economical way is given above 600. It is shown.

Immediately below the bar display 26 is a display 33 for the amount of energy present in the storage system or tank. The scale 34 of the tank contents display device 33 is appropriately non-linearly divided into the scale 27 of the reach, where the lower region 35 is, for example, between 0% and 50% of the tank contents. The larger scale is presented. The lower region 35 of the tank contents display 33 is included in its division in the lower region 28 in the reach scale 27 of the bar display 26, which is also in the corresponding upper region. It is the same.

FIG. 5 shows a bar display 16 constructed non-linearly on a scale 17 of reach. In FIG. 5 the scale is significantly increased in the lower region of the scale 17 of reach. In the embodiment shown in FIG. 5, the reach extends considerably for approximately 100 Km. The rod 19 is covered in an area of reach with a median of about 15 Km. In the upper region 20 of the scale 17 of reach, it is generally continued from the division 300 of the scale to the end 21 of the scale 17 of the reach in the display of reach of 600 or more, the scale is increased and then decreased. do.

6 shows a display device 1 composed of a digital display device 22. Two outer figures (23, 24) indicate the minimum and maximum reach distances. The center value 25 represents the expected reach in the actual driving mode.

All display units share a large difference between maximum reachable and minimum reachable in the upper area of large reach correlated with energy or fuel systems by significant storage. This difference is then reduced, for example, in an economical or sporty manner. The smaller the displayed reach range is, the larger the limit is for a smaller amount of energy storage.

At the time of calculation of the reach area, the filling state of the energy tank at that time is displayed as a start signal. That is, the amount of energy present and the consumption spectrum specific to the vehicle and, if necessary, the consumption spectrum specific to the driver are needed. In the case of limiting the reach area taking into account any driver-specific consumption spectrum, the reach area is usually designed at a common value, for example 75%. In addition, the narrowed reach range can be maximized by miscalculation of actual consumption while driving the vehicle. When the reach range is displayed, a continuous display appears in the display unit, which corresponds to the actual energy consumption.

Separately reachable display devices, warning lamps and / or current consumption display devices can be omitted as the display unit of the present invention. The display unit of the present invention can be used regardless of all the energy consumed in the engine, for example gasoline, diesel, current, solar energy or gas.
