Method of determining the tread depth in a vehicle tyre

摘要

The tire is initially identified and a tire slip of the driven wheels is determined under given driving conditions and evaluated in accordance with each driving condition. Information about the depth of the tire profile is issued from on board data corresponding to the identified tire and the tire slip value. Preferred Features: A mean is achieved from a number of profile depth outputs. Individual depth values evaluated according to driving condition and/or environmental influences are incorporated in the averaging method. Stored profile depth information from previous journeys is also considered when averaging.
