Motor vehicle navigation system that receives route information from a central unit |
摘要 |
Data indicative of an instantaneous location, a destination and a route from the instantaneous location to the destination are transmitted from a motor vehicle navigation unit to a central unit. Traffic information about the route between the instantaneous location and the destination are transmitted from the control unit to the vehicle unit. The received traffic information data are used by the vehicle unit to determine a desirable route between the instantaneous location and the destination given the traffic information. The data of the route thus determined are made available to the vehicle driver, so that he is able to steer toward his desired destination along this specified route.
