Method for ascertaining a wheel circumference of a vehicle wheel attached to a vehicle, a parking assistance system, a motor vehicle, a computer program and a computer-readable medium

摘要

A method is provided for ascertaining a wheel circumference of a vehicle wheel attached to a vehicle with reference to the distance travelled by the vehicle and measuring signals of a wheel revolution sensor associated with a vehicle wheel. The method includes, but is not limited to positioning the vehicle in front of a stationary obstacle and registering the obstacle with a distance measuring device of the vehicle, moving the vehicle in direction of the obstacle, ascertaining the distance travelled as the reference distance with the distance measuring device, ascertaining the number of measuring pulses of the wheel sensor over the distance travelled, and determining the wheel circumference from the ascertained distance and the ascertained number of measuring pulses of the wheel sensor. A parking assistance system is also provided for a motor vehicle, a motor vehicle, a computer program product and a computer program.
