Method for taking into account supplementary traffic information in an onboard travel control system

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;
• modifying, 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;
• and further comprising the step of:
• if a particular item of information relating to a traffic disturbance for a particular route segment is received by the onboard travel control system, then canceling a modification of a particular route segment by the onboard travel control system.

• if at least one of a particular time variation and a particular position variation exceed a particular threshold, then automatically revising the route plan via the central office.

A system for operating an onboard travel control device in a motor vehicle, the system comprising:

• the onboard travel control device includes an internal digital road map having route segments contained therein;
• means for taking into account supplementary traffic information for operating the onboard travel control device in the motor vehicle;
• means for transferring a point of origin and a destination from the onboard travel control device to a central computer of a central office, the onboard travel control device having information about location codes;
• the central computer calculates 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;
• means for transmitting the route plan from the central computer to the onboard travel control device;
• and
• wherein the internal digital road map is modified based upon 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 device.
