Abstract (en)
[origin: WO2018172317A1] The invention relates to a method for determining a profile depth (td) of a profile (4) of a tyre (2) while a vehicle (1) having the tyre (2) is operating, a control device (20) for a vehicle (1) for determining a profile depth (td) of a profile (4) of a tyre (2) of the vehicle (1), and a system (20, 12) for a vehicle (1), having such a control device (20) and at least one electronic wheel unit (12), wherein there is provision for the profile depth (td) to be determined on the basis of a determined instantaneous dynamic wheel radius (r1dyn) of a wheel (W) of the vehicle (1) having the tyre (2) and a determined instantaneous dynamic internal radius (r2dyn) of the tyre (2). In order to improve the determination of the profile depth (td) with respect to accuracy, a correction variable (F) which is determined in advance for the type of tyre (2) is taken into account, said correction variable (F) characterizing the relationship between, on the one hand, a change in the profile depth (td) and, on the other hand, a resulting change in the difference between the dynamic wheel radius (r1dyn) and the dynamic internal radius (r2dyn).
