Abstract
A method and a device for ascertaining a dynamic tire circumference of a transportation vehicle. The method includes: receiving a first signal representing a yaw rate of the transportation vehicle, a second signal representing a wheel rotation speed of a wheel of the transportation vehicle, a third signal representing a steering angle of the transportation vehicle, and a fourth signal representing a dynamic track width of the transportation vehicle; ascertaining a first output signal of a first Kalman filter that represents the dynamic tire circumference of the wheel, using the first signal, the second signal, the third signal, and the fourth signal as input signals for the first Kalman filter; and using the first output signal in a control unit of the transportation vehicle.
