Definitions

• Display unit for data dependent on the energy consumption of a vehicle
• the invention relates to a display unit for data dependent on the energy consumption of a vehicle according to the preamble of claim 1.
• a fuel display device is already known from DE-PS 30 46 076, which has means for measuring, evaluating and displaying the current fuel consumption and the data resulting therefrom.
• the following are displayed in detail: the range in the current driving state based on constant conditions in the form of a number, the fuel quantity in the fuel tank in the form of numbers, the lighting up of a colored lamp when a minimum quantity of fuel has been reached and the display of the current fuel consumption by three lamps of different colors, the lamps when illuminated indicate whether the fuel consumption is within, below or above a predetermined range.
• a disadvantage of this range display is that the numbers displayed change constantly due to the changing driving conditions and can thus lead to irritation and distraction of the driver.
• Another disadvantage is that these so-called on-board computers are generally only offered in vehicles of the higher price category or as special equipment.
• the object of the invention is to create a display unit for data dependent on the energy consumption of a vehicle, which clearly displays the most important data dependent on energy consumption and energy storage content.
• the display unit according to the invention has a range indicator, which shows the range to be expected, e.g. B. in kilometers, the driver indicates.
• this range is obtained as a function of the amount of energy currently in the energy storage system and the minimum and maximum average consumption of the vehicle engine in conjunction with the vehicle-specific parameters.
• the driver-specific features are also taken into account in the range range displayed.
• These driver-specific features can be, for example, sporty or economical driving styles. For example, an empirically determined range of average consumption, which is a predetermined percentage, eg. B. between 50-75%, of a driver's behavior that limits the range resulting from the vehicle-specific average consumption. A further restriction of this range which then results is possible by measuring and evaluating the driving behavior of a driver permanently assigned to the vehicle over a certain period of time. A minimum and maximum average consumption is determined from these data and used to calculate the range. The displayed range will then become even narrower.
• the display of the range of the vehicle means that the instantaneous amount of energy in the storage system or energy container can be omitted and the driver knows directly from the specified range of range how far he is with the still stored one Energy can still drive depending on the consumption of the vehicle and in different operating conditions.
• the minimum or maximum range is displayed by a pointer instrument with two pointers which can be controlled independently of one another.
• the range range is displayed via a bar display with a highlighted area, the highlighting being able to be colored and / or illuminated.
• the range is indicated on a digital display in the form of mutually spaced numbers.
• the range scale is divided on an enlarged scale from the range of the reserve quantity, so that the driver can precisely estimate the possible range. It is also advantageous if the range scale in the upper area, in which there is still a lot of energy in the energy container, has a smaller or narrower division.
• the energy reserve quantity can be displayed by changing the display color. This means that a separate reserve lamp can be omitted.
• the expected range is made visually perceptible with the current or current driving style within the highlighted or displayed range.
• a further advantageous embodiment of the display unit is characterized in that the range range specified is restricted or shortened by a constant or variable percentage.
• the upper area of the range scale is cut off, which affects in particular the range with a particularly economical driving style, ie the maximum range begins with an average or medium value.
• the limit values of the average consumption on which the underlying consumption is based can be changed automatically during driving operation using appropriate software. If the evaluation device of the display unit according to the invention determines that the empirically determined limit values are exceeded or undershot, then the restricted range is expanded and adapted to these limit values.
• the amount of energy currently in the energy container is displayed or can be called up.
• 1a, b and c each show a pointer instrument with a double pointer and a linear range scale, the double pointer each indicating different range ranges, namely the range range with an energy reserve quantity, with a half-full energy container and with a completely filled energy container ;
• 2a, b and c each show a bar graph with a linear range scale with a highlighted range of range, namely with an energy reserve quantity, a half-filled energy container and for a completely filled energy container;
• FIG. 3 shows a bar display corresponding to FIG. 2b, the range range highlighted being divided into two parts by a cutout or a window, and this window showing the range to be expected for the current range
• Fig. 4 shows a bar graph combined with a display of the
• Fig. 5 is a bar graph with a non-linear range
• FIG. 6 shows a digital display with the minimum and maximum range and the range to be expected in the current driving style.
• 1a, 1b and 1c each show a display device 1 designed as a pointer instrument 2 with two pointers 3 and 4.
• the pointer instrument 2 is provided with a linear range scale 5.
• the pointer instrument 2 is designed as a round instrument.
• the pointers 3 and 4 are controlled separately from one another and can be moved separately from one another.
• 1a relates to a range of range with an energy reserve quantity. As can be seen from FIG. 1a, the two pointers 3 and 4 are relatively close to one another due to the small range range.
• FIG. 1b indicates a range when the storage system or the energy container is half full.
• the two pointers 3 and 4 are far apart due to the relatively high energy reserve compared to the position in FIG. 1a.
• the range shown in FIG. 1c is restricted. As in the other FIGS. 1a and 1b, the pointer 3 indicates the minimum range. In contrast to FIGS. 1a and 1b, however, the pointer 4 does not show the maximum range, but an underlying range. This range can be determined, for example, from empirical values as an average value.
• a display device 1 which is designed as a bar display 6.
• the bar display 6 also has a linear range scale 7.
• the range is shown by an optically highlighted bar 8.
• the highlighting is done, for example, by illuminating the range that results from the amount of energy available. rich.
• the range scale 7 ends at a range that is below the maximum possible range.
• the bar 8 with its left boundary line 9, like the pointer 3, also indicates the minimum range. 2a and 2b, the right boundary line 10 represents the maximum range. Only in FIG. 2c is the right boundary line 10 shifted towards the left boundary line 9.
• a comparison of the bar in FIG. 2b with the bar in FIG. 2a shows that with a half-full energy container, the bar 8 is correspondingly long, while the bar 8 is correspondingly short with a small amount of energy. This results in a larger limitation of the possible range in a simple manner.
• FIG. 3 shows a bar graph 11 similar to the bar graph 6 of FIGS. 2a to 2c, but with the difference that a bar 12 of the bar graph 11, which indicates the range of coverage, is provided with a window 13 which shows the expected range Range indicates the current driving style.
• the bar 12 has a left and right boundary line 14 and 15, which represents the minimum and maximum range.
• a bar graph 26 is shown, in which the range scale 27 in a lower region 28, z. B. between 0 and 300 kilometers, is not divided linearly. Due to the spreading of this lower area 28 and the narrowing of the bar 30 indicating the range area 29, the remaining range is limited relatively precisely.
• the range scale 27 is provided with a tip at its end 32 which delimits the upper range 31, which symbolizes that the range is greater than the specified numerical value of in a correspondingly economical driving style 600 is.
• a display device 33 for the amount of energy currently in the storage system or in a tank is shown directly below the bar display 26.
• the scale 34 of the tank content display device 33 is not linearly divided according to the range scale 27, in that a lower area 35, for example between 0 and 50% of the tank content, is shown on a larger scale.
• the lower area 35 of the tank content display device 33 is divided into the lower area 28 of the range scale 27 Adjusted bar display 26, as is the case for the corresponding upper areas.
• 5 shows a bar graph 16 in which the range scale 17 is not linear. 5, the scale in the lower region 18 of the range scale 17 is greatly enlarged. In the example shown in FIG. 5, the range is widely spread for the remaining 100 kilometers. A bar 19 covers a range, the average of which is approximately 15 kilometers. In the upper region 20 of the range scale 17, which extends approximately from the scale division 300 to the end 21 of the range scale 17 with a range specification> 600, the scale is increasingly reduced.
• the 6 shows a display device 1 designed as a digital display 22.
• the two outer numerical values 23, 24 indicate the minimum and the maximum range, respectively.
• the average numerical value 25 stands for the expected range with the current driving style.
• All display units have in common that in the upper area of a long range, due to the high supply of energy or fuel, there is a large difference between a maximum possible and a minimum possible range, this difference being caused, for example, by an economical or sporty driving style.
• the range range displayed is the narrower and therefore the more limited the lower the energy reserve.
• the respective fill level of the energy container ie the currently available amount of energy and the vehicle-specific and possibly the driver-specific consumption spectrum, are required as input signals. If the range is limited by taking into account a general driver-specific consumption range, the range is usually reduced to a general value, e.g. B. designed for 75% of all eligible drivers. In addition, a narrowed range can also be optimized by calculating the actual consumption during driving.
• the display unit can be used to display the range a momentary display is shown that corresponds to the current energy consumption.
• the display unit can eliminate separate range indicators, warning lamps and / or instantaneous consumption indicators.
• the display unit can be used with all energies that can be processed by a motor, regardless of whether the energy is obtained, for example, from gasoline, diesel, electrical current, solar energy or gas, etc.
