Navigation device for motor vehicles and method for calculating and output at least one alternative roads route in the tailback case

摘要

The present invention relates to a navigation device (1) for motor vehicles with a position locating a direction (2) for determining the actual location position of the vehicle and with a central or decentralized traffic - evaluation unit (4) for receiving and evaluating purposes, as well as with a driving routes of determining a direction (3) with dynamic destination routing which an automatic calculation of at least one alternative street route (asr) in the tailback case contains. It is proposed that when the destination guidance function in the case of traffic disruption was the calculation and output at least one alternative street route (asr) is carried out.
