Abstract

A method for ascertaining a wheel circumference of a driven wheel of a vehicle includes measuring a rotational speed of the driven wheel during a predefined time span, measuring an acceleration of the vehicle in the direction of the longitudinal axis of the vehicle during a predefined time span, determining a distance traveled by the vehicle based on the measured acceleration, and determining the wheel circumference of the driven wheel based on the measured rotational speed and the ascertained distance traveled.
