METHOD FOR ESTIMATING THE TREAD DEPTH OF VEHICLE TYRES FOR VEHICLES WITH TWIN TYRES

The invention relates to a method for estimating the tread depth of vehicle tires in a vehicle with dual-tire configuration, comprising the following method steps: a) driving a dual-tire vehicle along a predetermined driving distance in a driving section, b) determining a plurality of driving parameters (10) of the vehicle during driving, wherein the plurality of driving parameters (10) comprises at least the lateral acceleration, as well as for each of the inner vehicle tire and the outer vehicle tire of the dual-tire configuration the following method steps: c) calculating the forces (12) acting on the vehicle tires in the driving section on the basis of the determined driving parameters (10) and determining an abrasion severity number (14) assigned to the driving section from the calculated forces (12) taking into account a plurality of influencing parameters (16) which are selected from the group consisting of vehicle parameters (16a), environmental parameters (16b) and tire parameters (16c), wherein the influencing parameters (16) comprise at least information about the tread material and about the initial tread depth, wherein the position of the respective vehicle tire in the dual-tire configuration is taken into account by a position correction factor (18), and d) estimating the final tread depth for the vehicle tire on the basis of the respective initial tread depth taking into account the respective abrasion severity number (14).
