Title: METHOD AND DEVICE FOR DETERMINING WHEEL LOADS ON WHEELS OF A VEHICLE
Abstract:
The invention relates to a method and to a device for determining wheel loads (LD, L0) on wheels (W1-W4), which are respectively equipped with a tyre, of a vehicle (1). In this context, in a first phase (S1), in each case a deformation measured value (L) and a pressure measured value (P) are detected for the respective tyres, and at least one acceleration measured value (ax, ay) is detected for the vehicle (1) in order to calculate the dynamic wheel loads (LD) of the respective wheels (W1-W4) according to a first model, and in order to calculate static wheel loads (L0) of the respective wheels (W1-W4) according to a second model, wherein the second model contains at least one model parameter (c1FL to c2RL). The at least one model parameter (c1FL to c2RL) is calculated by means of a statistical analysis (S2) of the calculated dynamic wheel load (LD), of the respectively calculated static wheel load (L0) and of the respectively detected at least one acceleration measured value (ax, ay). In a second phase (S3), renewed detection of the at least one acceleration measured value (ax, ay) and renewed calculation of the dynamic wheel load (LD) of the wheels (W1-W4) from the previously calculated static wheel loads (L0) of the wheels (W1-W4) and the at least one newly detected acceleration measured value (ax, ay) are carried out according to the second model, wherein the previously calculated at least one model parameter (c1FL to c2RL) of the second model is used.
