摘要： A method for determining a longitudinal force acting during tire rotation on a tire mounted on a wheel rim includes the step of determining the torsional deformation of the tire, which is a function of the location of measurement, between a radially inner area of the wheel or the hub and a radially outer area of the tire in at least one non-rotating position. At least two marks are positioned at the wheel on different radii relative to an axis of rotation of the wheel, wherein a radially outer mark is positioned on a radially outer area of the tire. At least two sensors are non-rotatingly arranged in the vicinity of the wheel so as to be positioned on the different radii, wherein a radially inwardly arranged sensor is connected to a steering knuckle and a radially outwardly arranged sensor is connected to a transverse suspension arm of the wheel suspension. For the rotating wheel at least one time period between passing of the at least two marks at the at least two sensors is recorded. The torsional deformation is computed from the at least one time period. The longitudinal force is calculated from the torsional deformation. Other tire parameters such as tire air pressure, footprint length, tire spring travel, load/pressure ratio can also be calculated with variants of the disclosed method.
