Method and Device for Estimating a Current Wheel Circumference of at Least One Wheel Arranged on a Vehicle

A device for estimating a current wheel circumference of at least one wheel arranged on a vehicle, said device comprising:

• an input apparatus;
• a calculation apparatus;
• a circular buffer;
• and
• an output apparatus;
• wherein the input apparatus is configured to receive a reference speed of the vehicle from a reference apparatus at least at one point in time and to receive a wheel rotational speed of the at least one wheel from a wheel rotational speed sensor at the at least one point in time;
• wherein the calculation apparatus is configured to estimate a wheel-circumference value based on the received reference speed and the received wheel rotational speed for the at least one point in time and to store at least the wheel-circumference value for said point in time in the circular buffer;
• wherein, in case a plurality of wheel-circumference values are stored in the circular buffer for a plurality of points in time, the calculation apparatus is configured to estimate a current wheel circumference based on the plurality of wheel-circumference values stored in the circular buffer;
• and
• wherein the output apparatus is configured to output the estimated current wheel circumference for further processing.
