Abstract: |
A method for determining a tread depth of a tread of a tire during operation of a vehicle comprising the tire, a controller for a vehicle for determining a tread depth of a tread of a tire of the vehicle, and a system for a vehicle, comprising such a controller and at least one electronic wheel unit, wherein there is provision to determine the tread depth based on a determined instantaneous dynamic wheel radius of a wheel, comprising the tire, of the vehicle and a determined instantaneous dynamic inside radius of the tire are disclosed. To improve the accuracy of determination of the tread depth a correction variable predetermined for the type of tire is taken into consideration, which correction variable characterizes the relationship between a change in the tread depth, and a change resulting therefrom in the difference between the dynamic wheel radius and the dynamic inside radius. |
