Patent ID: 8447457

Claim:
A method for controlling air pressure in tires as a function of a driving situation, the tires being able to be mounted on two driven axles of a motor vehicle, an engine torque being distributable to the two axles by a distributor clutch, the method comprising: converting a plurality of input values into an air pressure value describing an air pressure in each tire in a processing unit; and processing a clutch friction value reflecting a clutch status into a control value in the processing unit; wherein a rolling value describing a rolling behavior of a tire at an initialization instant is detected, wherein the rolling value is stored as a setpoint value in a memory, wherein the rolling value stored as the setpoint value is subsequently compared with the control value, which was determined at a different instant and characterizes the rolling behavior of the tire at the instant, wherein if a limit value is exceeded or undershot, an action is started, the action including an actuation of an alarm signal output device, and wherein the processing unit also processes at least one of (a) a wheel circumference speed value describing a wheel circumference speed and (b) a natural frequency value of a wheel describing a natural frequency of the wheel.
