Abstract

The present invention relates to an axle-monitoring system of a chassis of a utility vehicle for acquiring data on at least one axle of the chassis, wherein at least one sensor for acquiring at least one physical variable is arranged on the at least one axle, wherein the at least one sensor is configured to acquire a multiplicity of different physical variables, and to the use of an axle-monitoring system.

Claims

1-12. -12. (canceled)

13. An axle-monitoring system of a chassis of a utility vehicle of a truck or trailer configured to acquire data on at least one axle of the chassis, comprising:

a plurality of sensors configured to acquire at least one physical variable is arranged on the at least one axle;

wherein the plurality of sensors are configured to acquire a multiplicity of different physical variables;

wherein, in order to reduce the data volume, the acquired physical data are stored in clustered groups;

wherein the acquisition comprises at least the following physical variables;

a temperature of the axle, a material stress of the axle and a speed at which the axle is moving; and

wherein the axle-monitoring system also comprises a memory for storing the acquired physical data.

14. The axle-monitoring system as claimed in claim 13, wherein the at least one sensor is configured to acquire the multiplicity of different physical variables.

15. The axle-monitoring system as defined in claim 13, where the at least one sensor is configured to acquire the multiplicity of different physical variables successively.

16. The axle-monitoring system as defined in claim 13, where the at least one sensor is configured to acquire the multiplicity of different physical variables continuously.

17. The axle-monitoring system as defined in claim 13, where the at least one sensor is configured to acquire the multiplicity of different physical variables at predefined points in time.

18. The axle-monitoring system as claimed in claim 13, wherein the multiplicity of different physical variables comprises at least the acquisition of one of the following physical variables:

acquiring a pressure which is present at the axle, acquiring an oscillation which has occurred at the axle, acquiring a positive or a negative acceleration with which the axle is accelerated or braked, acquiring location data by means of GPS, acquiring moisture on or around the axle, acquiring an air pressure at the axle, acquiring a roadway route, in particular a negative gradient of a roadway or a type of roadway, acquiring material changes of the axle, in particular an electrical resistance, acquiring distances or positions of the axle with respect to a roadway or with respect to another axle, and/or acquiring corrosion on the axle.

19. The axle-monitoring system as claimed in claim 18, wherein the plurality of sensors are arranged and configured in such a way that the different physical variables are acquired at various locations on the chassis or at a central location on the chassis.

20. The axle-monitoring system as claimed in claim 19, further comprising:

a controller configured to evaluate or pass on data.

21. The axle-monitoring system as claimed in claim 20, wherein the controller is configured to output a fault message if an evaluation of an acquired physical variable reveals that at least one parameter, acquired the at least one axle, of a physical variable deviates from a specified standard.

22. The axle-monitoring system as claimed in claim 20, further comprising:

an access-securing unit configured to limit access to the acquired physical data to selected persons or selected external systems.

23. The axle-monitoring system as claimed in claim 22, wherein the at least one axle has an axle identifier to which the acquired physical variables can be linked or to which the axles in the chassis of the utility vehicle can be linked, in order to document the continuous history of the at least one axle in the chassis.

24. The axle-monitoring system as claimed in claim 23, wherein the axle-monitoring system is connected to a warning system which outputs a warning message after a deviation of a parameter of an acquired physical variable from setpoint values stored in the controller is detected.

25. The axle-monitoring system as claimed in claim 24, wherein the axle-monitoring system is mounted on a trailer which is connected to the utility vehicle.

26. The axle-monitoring system as claimed in claim 13, wherein the plurality of sensors are arranged and configured in such a way that the different physical variables are acquired at various locations on the chassis or at a central location on the chassis.

27. The axle-monitoring system as claimed in claim 13, further comprising:

a controller configured to evaluate or pass on data.

28. The axle-monitoring system as claimed in claim 27, wherein the controller is configured to output a fault message if an evaluation of an acquired physical variable reveals that at least one parameter, acquired the at least one axle, of a physical variable deviates from a specified standard.

29. The axle-monitoring system as claimed in claim 13, further comprising:

an access-securing unit configured to limit access to the acquired physical data to selected persons or selected external systems.

30. The axle-monitoring system as claimed in claim 13, wherein the at least one axle has an axle identifier to which the acquired physical variables can be linked or to which the axles in the chassis of the utility vehicle can be linked, in order to document the continuous history of the at least one axle in the chassis.

31. The axle-monitoring system as claimed in claim 13, wherein the axle-monitoring system is connected to a warning system which outputs a warning message after a deviation of a parameter of an acquired physical variable from setpoint values stored in the controller is detected.

32. The axle-monitoring system as claimed in claim 13, wherein the axle-monitoring system is mounted on a trailer which is connected to the utility vehicle.
