Abstract
A method for predicting the temperature (T) of a wheel bearing of a vehicle wheel for a future moment (t+Δt) in relation to a present moment (t) or for a future time interval (t, t+Δt) in relation to a present moment (t), on the basis of a course of the temperature (T) of the wheel bearing in a past time interval (t−Δt, t) in relation to the present moment (t), the predicted temperature (T) of the wheel bearing being determined from the sum of the temperature (T) of the wheel bearing at the present moment (t) and a corrective value (ΔT) which is determined according to a change in at least one driving condition, such as the speed (Δv), and a change in the temperature (ΔT) of the wheel bearing within the past time interval (t−Δt, t).
