Abstract
A method and a measuring system determine a wheel load. These involve measuring a deformation of a tire and using a set of equations and equation parameters to calculate from the deformation the wheel load acting on the tire. In addition, a wheel load or a variable dependent on the load, which is used to calculate the wheel load, is received from an external system. Finally, the two wheel loads determined in different ways are compared, and the equations and/or equation parameters are adapted on the basis of the comparison.

A method for determining a wheel load, which comprises the steps:
- a) receiving a measurement of a deformation of a tire resulting in a measured deformation;
- b) calculating the wheel load acting on the tire using the measured deformation and a set of equations and equation parameters;
- c) receiving from an external system one of a further wheel load and a variable dependent on the further wheel load, which is used to calculate the further wheel load;
- d) comparing the wheel load determined in step b) with the further wheel load determined in step c);
- and
- e) adapting at least one of the set of equations and the equation parameters on a basis of the comparing step.
A measuring system for determining a wheel load, the measuring system comprising:
- a) receiving means for receiving a measurement of a deformation of a tire and outputting a measured deformation;
- b) means for calculating the wheel load acting on the tire using the measured deformation and a set of equations and equation parameters;
- c) means for receiving from an external system one of a further wheel load and a variable dependent on the further wheel load, which is used to calculate the further wheel load;
- d) comparison means for comparing the wheel load that was determined using said means cited in step b) with the further wheel load that was determined using said means cited in step c);
- and
- e) adaptation means for adapting at least one of the set of equations and the equation parameters on a basis of a comparison.
