Method for informing at least one receiver vehicle about a wrong-way vehicle, and server device and motor vehicles

A method for notifying at least one receiver vehicle about a wrong-way driver vehicle comprising:

• receiving, at a stationary server device, wrong-way driver data;
• producing, at the stationary server device, a digital road map divided into a plurality of sub-areas;
• based on the wrong-way driver data, selecting, at the stationary server device, a sub-area of the plurality of sub-areas in which the wrong-way driver vehicle is located;
• updating, at the stationary server device, map data of the sub-area based on the wrong-way driver data;
• transmitting, from the stationary server device to the at least one receiver vehicle, the updated map data of the sub-area;
• entering, at the at least one receiver vehicle, the updated map data of the sub-area into an on-board digital road map;
• checking, at the at least one receiver vehicle, a predetermined relevance criterion met by the wrong-way driver vehicle based on the on-board digital road map,
• wherein the wrong-way driver data comprises at least a current position of the wrong-way driver vehicle,
• wherein the wrong-way driver data is sent from the wrong-way driver vehicle, an other vehicle, or a permanently installed monitoring device,
• wherein the plurality of sub-areas are of a predetermined size, and
• wherein the predetermined relevance criterion comprises:
• a planned or an estimated route of the at least one receiver vehicle intersecting a route of the wrong-way driver vehicle;
• the current position of the wrong-way driver vehicle being in the direction of travel of the at least one receiver vehicle;
• the current position of the wrong-way driver vehicle being in front of the at least one receiver vehicle;
• an indication of the at least one receiver vehicle and the wrong-way driver vehicle being on the same road based route data of the at least one receiver vehicle and route data of the wrong-way driver vehicle;
• and
• a same roadside shared by the at least one receiver vehicle and the wrong-way driver vehicle.

A motor vehicle, comprising:

• a control device comprising a processor configured to:
• receive, from a stationary server device, map data of a sub-area in which a wrong-way driver vehicle is located ;
• enter the map data of the sub-area into an on-board digital road map;
• check a predetermined relevance criterion met by the wrong-way driver vehicle based on the on-board digital road map;
• in response to the predetermined relevance criterion being met, perform at least one protective measure,
• wherein the predetermined relevance criterion comprises:
• a planned or an estimated route of the at least one receiver vehicle intersecting a route of the wrong-way driver vehicle;
• the current position of the wrong-way driver vehicle being in the direction of travel of the at least one receiver vehicle;
• the current position of the wrong-way driver vehicle being in front of the at least one receiver vehicle;
• an indication of the at least one receiver vehicle and the wrong-way driver vehicle being on the same road based route data of the at least one receiver vehicle and route data of the wrong-way driver vehicle;
• and
• a same roadside shared by the at least one receiver vehicle and the wrong-way driver vehicle,
• thereby enabling the motor vehicle to perform as a receiver vehicle for the stationary server device by receiving notification about the wrong-way driver vehicle over an Internet.
