Abstract

According to the invention, primary route information, which describes a primary route of a mobile unit, is determined for said mobile unit. The primary route information is then evaluated using fuzzy logic, determining the maneuver information.

Claims

1. A method for determining maneuver information from a record of predeterminable maneuver information for a mobile unit using fuzzy logic,

wherein primary route information, which describes a primary route of the mobile unit, is determined,

wherein the primary route information is evaluated using fuzzy logic, whereby the maneuver information item is determined such that

a) first memberships are determined for the primary route information using fuzzy membership functions, with which first memberships the membership of the primary route information item of one of the predeterminable maneuver information items is described in each case,

b) and the first memberships are evaluated using rules, whereby the maneuver information item is determined.

3. A method according to claim 1 or claim 2,

wherein the primary route information describes a route to be covered by the mobile unit and/or the secondary route information describes a route which can be covered as an alternative to the route to be covered.

4. A method according to any one of the preceding claims, wherein the primary route information and/or the secondary route information is/are described by a direction change, in particular by an angle of direction change.

13. A method according to claim 12,

wherein the performance value is determined for each of several fuzzy rules and the performance values are combined into an overall performance value.

14. A method according to claim 13,

15. A method according to any one of the preceding claims, used in a navigation system, in particular in a navigation system for a motor vehicle, wherein the mobile unit is the motor vehicle.

17. A computer program with program-code means in order to implement all the steps according to claim 1 or claim 2 if the program is executed on a computer.

18. A computer program with program-code means according to claim 17, which program-code means are stored on a computer-readable data medium

19. A computer-program product with program-code means stored on a machine-readable medium, in order to implement all the steps according to claim 1 or claim 2 if the program is executed on a computer.

21. A method according to claim 1,

wherein the primary route information describes a route to be covered by the mobile unit and/or the secondary route information describes a route which can be covered as an alternative to the route to be covered.

22. A method according to any one of the preceding claims,

wherein the primary route information and/or the secondary route information is/are described by a change of direction, in particular by an angle of change of direction.

23. A method according to any one of the preceding claims,

wherein the primary route information and/or the secondary route information is/are determined using a digital map containing routes.

24. A method according to any one of the preceding claims,

wherein the maneuver information item determined is output to a user by means of at least one of the following types of output:

an optical display of the maneuver information item determined,

an acoustic output of the maneuver information item determined.

25. A method according to any one of the preceding claims,

wherein the fuzzy membership functions and/or the fuzzy rules are adapted to a type of output of the maneuver information item determined.

26. A method according to any one of the preceding claims,

wherein, in carrying out the evaluation using fuzzy logic, a significance is determined for one of the predeterminable maneuver information items, which significance describes a certainty in respect of this one predeterminable maneuver information item.

27. A method according to claim 7,

wherein this predeterminable maneuver information item is evaluated using the significance.

28. A method according to any one of the preceding claims,

wherein the first and/or second memberships are each coded as a bit-pattern.

29. A method according to any one of the preceding claims,

wherein a rule base is created which comprises fuzzy rules selected from the fuzzy rules.

30. A method according to any one of the preceding claims,

wherein a performance value is determined for a fuzzy rule, with which performance value a degree of performance of a rule result of the fuzzy rules is described.
