Method and device for determining the circumference of a wheel

摘要

The method involves determining a circumference of the wheel depending upon yaw rate of the vehicle, rotational speed of the two wheels (11,12) and distance between these two wheels. The circumference of the wheels is measured depending on the yaw rate and the rotational speed is measured depending on the distance. The circumference is only determined if the yaw rate is greater than fifteen degrees per second. Independent claims are also included for the following: (1) wheel circumference determination device (2) vehicle.
