For this purpose, this information is linked to each other before starting and / or driving on a route and evaluated with respect to a predetermined or variably changing vehicle operating mode. Subsequently, the remaining range of the electric vehicle is calculated from this information and / or the evaluation result and displayed in a display device.
  • DE 10 2008 037 262 A1 discloses a method for outputting a determined remaining range of a tank filling of a vehicle in an optical output unit of a navigation system of a vehicle.
  • the determined remaining range of the tank filling is alphanumerically as a distance from a current position of the vehicle a display in the optical output unit.
  • the distance is output as a polygonal line closed at the current position, wherein an inner area enclosed by the polygonal line is output differently in relation to an outer area lying outside the traverse.
  • DE 43 44 369 A1 discloses a method for consumption-oriented driving power limitation of a vehicle drive as a function of a travel destination and the energy supply of the energy storage providing the drive power.
  • the driver prescribes, via an input unit to a travel computer, travel information from which at least the total distance to the destination can be determined.
  • the travel computer repeatedly determines the allowable target route consumption during the journey on the basis of the measured current energy supply to overcome the distance ahead.
  • a default value is derived, which serves as a default for a device for driving power limitation in such a way that the driving performance is limited the more, the smaller the determined target route consumption is.
  • DE 692 04 811 T2 discloses a remaining range indicating device for a vehicle powered by a storage battery.
  • the type of road that is traveled by the electric vehicle identified as well as the distance that can drive the electric vehicle, calculated depending on the nature of the road and displayed on a display device.
  • the object of the invention is to simplify the operation of a motor vehicle with a limited power supply. This object is solved by the inventions given in the independent claims. Advantageous embodiments emerge from the dependent claims.
  • ranges of the motor vehicle on a first class routes calculable and ranges on paths of a second class can be determined by estimation.
  • An estimate is understood to mean a determination with a lesser (computation) effort than is carried out for a calculation of first-class paths.

  • the ranges are estimated on second-class routes such that a straight line connecting a maximum-range point (range limit) on one of the second-class paths to the starting point of the range calculation is shorter than a straight line that has a maximum-range point connects a neighboring path of the first class with the starting point of the range calculation.

  • the roads are divided into a plurality of classes, ranges are calculated on first class routes, and ranges are estimated by second-class routes.

  • a 50 km long route on a motorway would lead to the same result as a 50 km long route through a city.
  • a route reference is preferably used to calculate the range.
  • the idea is to use a simulation model of the motor vehicle, which takes into account the energy expenditure for overcoming a defined height and speed profile in order to calculate the remaining residual range.

If the height profile in the motor vehicle is not available, this profile could be downloaded via an online query from the Internet. The now available altitude profile, together with the expected speeds, which result from the classes and the current traffic situation, is transferred to a vehicle model. This is now able to calculate the point Ri, which indicates how far the motor vehicle can travel on exactly this route with the remaining energy content.
