摘要： A system for determining a tire contact area parameter includes a sensor module on the tire. The sensor module has a sensor that receives a sensor signal which is dependent on a mechanical tire load at a predetermined measuring point on the tire. A first evaluation device evaluates the sensor signal and provides data based on the sensor signal. The data contain a data element which indicates a time point in the sensor signal. The time point characterizes a passage of the measuring point through the tire contact area. A second evaluation device calculates the tire contact area parameter by evaluating the data provided by the first evaluation device. The first evaluation device analyzes the sensor signal based on a predetermined evaluation criterion with respect to the signal quality of the sensor signal to provide signal quality information of the sensor signal.

摘要： A method for determining a tire tread depth during operation of a vehicle includes determining an instantaneous rotational speed of a vehicle wheel having the tire based on data determined by at least one first sensor, then determining a vehicle speed based on data determined by at least one different second sensor, then determining an instantaneous dynamic wheel radius based on the determined instantaneous rotational speed and the determined instantaneous speed. At least one first tire parameter selected from an instantaneous tire temperature, tire pressure and tire load is determined. An instantaneous dynamic inner wheel radius is determined based on the at least one determined first parameter, wherein the inner wheel radius is the distance between the center of the wheel and the tire-side start or seam of the tread. A tire tread depth is determined based on the determined instantaneous dynamic radius and the determined instantaneous dynamic inner radius.
