Abstract:
A method for taking into account supplementary traffic information for operating an onboard travel control system of a motor vehicle, the onboard travel control system including an internal digital road map having route segments, comprising the steps of:transferring a point of origin and a destination from the onboard travel control system to a central computer of a central office, the onboard travel control system having information about location codes;calculating, via the central computer, a route plan that takes into account the supplementary traffic information, the route plan including route segments that are defined by the location codes, the route segments being disposed between the point of origin and the destination;transmitting the route plan from the central computer to the onboard travel control system; andmodifying, in the internal digital road map, the transmitted route segments so that the transmitted route segments are assigned a higher priority over the route segments in the internal digital road map during subsequent route selection, the subsequent route selection being carried out by the onboard travel control system.
