Abstract: The invention relates to a method for ascertaining a yaw-rate offset value (?offset) which represents the offset of yaw-rate measurement values of a yaw-rate sensor (2) of a motor vehicle (1). The method has the following steps: receiving (100) a plurality of yaw-rate measurement values (?1, . . . , ?x) from the yaw-rate sensor (2) over time (t), said measurement values constituting a yaw-rate measurement signal (S?); checking (200) whether the motor vehicle (1) is at a standstill; and if so, ascertaining (500) the yaw-rate offset value (?offset) on the basis of the yaw-rate measurement signal (S?). The method is characterized by the steps of ascertaining (300) yaw-rate measurement values (Gst) which form a slope (St) in the yaw-rate measurement signal (S?); and disregarding (400) the ascertained yaw-rate measurement values (Gst) which form a slope (St) in order to ascertain (500) the yaw-rate offset value (?offset).
