Abstract

Disclosed is a method for automatically identifying a type of vehicle or a type of tire on a test stand. Said method comprises the following steps: a) predetermined parameters characterizing the type of vehicle or type of tire are supplied; b) a test stand encompassing a plurality of sensors is provided; c) at least some areas of a vehicle or tire are sensed on the test stand; d) at least one vehicle or tire property is determined from values sensed by means of at least some of the sensors. Said method is characterized in that: e) the properties determined in step d) are compared with the predetermined parameters; f) the type of vehicle or type of tire is assigned based on the result obtained in step e), or parameters of a new type of vehicle or type of tire are defined if a type of vehicle or type of tire cannot be assigned because properties fail to match the parameters.

Claims

1-6. -6. (canceled)

7. A method for the automatic identification of a type of vehicle on a test stand, comprising the steps:

a) delivery of predetermined parameters that characterize the type of vehicle or the type of tire;

b) delivery of a test stand which has a plurality of sensors;

c) sensing of at least areas of a tire on the test stand;

d) determination of at least one characteristic of the vehicle from values, at least some of which have been sensed by the sensors;

e) comparison of the characteristics determined in Step d) with the predetermined parameters; and

f) classification of the type of vehicle on the basis of the result from Step e) or, if a classification is not possible on account of a lack of coherence of characteristics with the parameters, definition of parameters or a new vehicle model.

8. The method according to claim 7, wherein at least one of the characteristics tire width, tire tread, rigidity of the tire, tire pressure, tire load, number of tires per axle, track width of at least one axle of the vehicle, the distances between the individual axles, current axle load, load distribution over the axles and the total weight of the vehicle are sensed or are determined from sensed values.

9. The method according to claim 7, wherein the type of vehicle is associated with nominal values and/or tolerances for the measured operating parameters of the vehicle.

10. The method according to claim 7, wherein a verification is performed to determine whether a sensed or measured value lies within a specified range of nominal values or tolerance, and if the value lies outside the range of nominal values or tolerance, an action is carried out which brings the value into the range of nominal values or tolerance.

11. The method according to claim 7, wherein a weighting is associated with each parameter, the weighting being included in Step f) of the classification of the type of vehicle.

12. The method according to claim 7, wherein an acceptance range is associated with each parameter, whereby the acceptance ranges for the parameters of each type of vehicle are adjusted so that the classification in Step f) is clear and unambiguous.
