Method for operating a coefficient of friction database, coefficient of friction database and control unit

摘要

The invention relates to a method for operating a coefficient of friction database in which information sent by transmitting vehicles is received and stored in the database, the information comprising at least the determined coefficient of friction potential of a road segment describing friction data and the geographical position of this road segment descriptive location data in the DB = EPODOC & ... PN = EP0808361 The data stored in the database may be plausibility checked and converted into plausible data and the plausible data stored in the database retrieved from receiving vehicles, the friction coefficient data being the information that a low friction value is present and the information being provided by the sending vehicles are only sent when a present low friction coefficient is determined.
