Description

The invention relates to a method for operating a motor vehicle.

From the DE 63 02 504 A1 For example, a method for determining a range of an electric vehicle is known in which a remaining range is calculated and displayed.

Especially for motor vehicles with electric drive display devices are known that indicate a certain residual range. The remaining range is determined from a remaining range based on the consumption values of a previous trip minus a correction value based on current consumption values.

However, these numerically displayed values are not very clear and require the motor vehicle driver to set these values in relation to a desired route while driving, which reduces his attention to the current traffic situation and thus increases the risk of accidents.

It is therefore an object of the invention to show ways how a motor vehicle driver can be informed in an intuitively easier-to-understand way about a remaining range.

• – Bestimmen der Reichweite des Kraftfahrzeugs,
• – Erzeugen eines Datensatzes zur Erzeugung eines ersten Symbols mit einer Haupterstreckungsrichtung, die die bestimmte Reichweite (R) repräsentiert, und
• – Anzeigen des ersten Symbols, und
• – Erfassen einer gefahrenen Strecke und Erzeugen eines zweiten Datensatzes zur Erzeugung eines zweiten Symbols, wobei der zweiten Datensatz Positionsdaten enthält zur Positionierung des zweiten Symbols in Bezug zum ersten Symbol, derart, dass das zweite Symbol an einer Position entlang der Haupterstreckungsrichtung angeordnet wird, die der Länge der gefahrenen Strecke entspricht, und Anzeigen des zweiten Symbols.

The object of the invention is achieved by a method for operating a motor vehicle, comprising the steps:

• Determining the range of the motor vehicle,
• Generating a data record for generating a first symbol with a main extension direction, which represents the determined range (R), and
• - Display the first icon, and
• Detecting a traveled distance and generating a second data set for generating a second symbol, wherein the second data set contains position data for positioning the second symbol relative to the first symbol, such that the second symbol is arranged at a position along the main extension direction, which the Length of the distance traveled corresponds to and display of the second symbol.

As a result, a simple intuitive way of detecting a residual range is given, since the positioning of the second symbol with respect to the first symbol represents an easily detectable measure of the remaining range. By the second symbol, the motor vehicle driver receives additional information about the distance already traveled, in relation to the specific range.

According to one embodiment, it is provided that the first symbol is bar-shaped. Thus, the first symbol may have a simple shape.

In the area of the symbol numerical values can also be displayed in the main extension direction, which indicate the distance already traveled by the specific range and the remaining distance still possible.

According to a further embodiment, it is provided that changes in the range are detected and, based on detected changes, the position of the second symbol with respect to the first symbol and / or the numerical values in the region of the symbol in the main extension direction are adjusted. In other words, a range determined at the beginning of a journey is updated according to current consumption values based on the range determined at the beginning of the journey. Changes in the range are thus shown in relation to the residual range determined at the beginning of the journey. Thus, a motor vehicle driver is informed about a current residual range development.

According to a further embodiment, the second symbol is arrow-shaped. Thus, the distance covered in relation to the specific remaining range particularly accurately displayed.

Furthermore, the invention includes a computer program product comprising software components for carrying out such a method and a motor vehicle as well as a data processing device for such a motor vehicle.

The invention will now be explained with reference to a drawing. Show it:

1 an embodiment of a display device of a motor vehicle at the beginning of a journey, and

2 the 1 display device shown at a later time of the ride, and

3 the 1 Display device shown at a later time of the journey.

It is going on first 1 Referenced. Shown is a display device 8th a motor vehicle, such as a car. The motor vehicle may have a battery powered electric drive or an internal combustion engine or a hybrid drive.

In 1 the situation is shown at the beginning of a journey. A module of the motor vehicle for determining the range R of the motor vehicle at the beginning of a journey has determined the state of charge of the batteries on the commissioning of the motor vehicle by a motor vehicle driver and based on stored consumption data of a previous trip with the motor vehicle determines a range.

The determined range R becomes a data processing device 6 of the motor vehicle, this a first data set D1 to generate a first symbol 2 assigns so that the record represents the specific range. Here is the first symbol 2 formed in the present embodiment bar-shaped with a main extension direction H in the longitudinal direction of the beam. The right end of the bar represents the point where the specific range is used up. If the specific range eg. As in 1 90 km is the right end of the bar 2 for a distance of 90 km. If the determined range were only 60 km, the right end of the beam would be 2 stand for a distance of 60 km. The left end of the bar, on the other hand, represents the beginning of the journey, ie 0 km. The first data record D1 then becomes the display device 8th transferred and visualized there the motor vehicle driver.

Furthermore, the data processing device generates 6 a second record D2. The second data set D2 contains position data for positioning the second symbol 4 in relation to the first symbol 2 , such that the second, in the present embodiment, arrow-shaped symbol 4 is arranged at a position along the main extension direction H, which corresponds to the length of the traveled route S. In other words, the position of the arrow-shaped symbol 4 splits the bar such that the ratio of the bar section to the left of the arrow-shaped icon 4 to the bar section to the right of the arrow-shaped symbol 4 corresponds to the proportion of the distance traveled at the particular route. The second data record D2 then becomes the display device 8th transferred and visualized there the motor vehicle driver.

Since after the commissioning of the motor vehicle no distance S has been covered is the second symbol 4 corresponding to one end of the bar-shaped first symbol 2 arranged, in the present embodiment at the left end.

Further, the determined range R is in numerical form on the display device 8th displayed and arranged in the area of the beam.

For this purpose, the data processing device 6 in the present embodiment, hardware and / or software components.

It is now additionally on 2 Referenced. Shown is the situation at a later date. On the one hand, it has been detected that the motor vehicle has covered a distance S of 20 km since commissioning and generates a corresponding second data record D2 and the display device 8th transfer. Accordingly, there is the second symbol 2 not on the left end, but was shifted to the right.

Furthermore, the traveled distance S is in numerical form on the display device 8th displayed and in the area of the bar between the left end and the current position of the second symbol 4 arranged.

Furthermore, the consumption values of this journey were recorded and the range R determined at the beginning of the journey was updated. Due to the higher fuel consumption during this trip compared to the previous trip, the current range R is reduced from 90 km to 80 km, so that the right end of the beam now represents 90 km instead of 80 km. The second symbol 2 is positioned so that its position divides the bar such that the ratio of the bar portion to the left of the second symbol 2 to the bar section to the right of the second symbol 2 corresponds to the proportion of the driven route at the updated specific route.

Further, the determined range R minus the already traveled distance S - 60 km in the present embodiment - in numerical form on the display device 8th displayed and in the area of the bar-shaped first symbol 2 between the current position of the second symbol 4 and the right end of the first symbol 2 arranged.

It is now additionally on 3 Referenced. The situation is shown at an even later stage shortly before the end of the journey.

Due to the constant increase in fuel consumption compared to the previous drive, the range R has been shortened to 76 km, with the distance S now being 72 km. Thus, now is the second icon 4 near the right end of the first bar-shaped symbol 6 and indicates a remaining range of now 4 km. This information allows a motor vehicle driver in a particularly simple way to assess whether the remaining range is sufficient to achieve his goal.

Furthermore, it can be provided that a fall below a predetermined residual range the motor vehicle driver a reserve test range with the display device 8th is displayed, for example, as in the in 3 illustrated case by a colored highlighting.

Thus, the motor vehicle driver is given a particularly intuitive way of detecting a residual range of the motor vehicle.
