Driver-assistance system for keeping a vehicle in a lane when crossing an intersection by using local map data received from a transmitter located within a zone of the intersection

A method for keeping a vehicle in a lane by a driver-assistance system, the driver-assistance system has a receiver and a control system, the method comprising the following steps:

• receiving local map data by means of the receiver from a transmitter located within a zone of an intersection, wherein the local map data specifies a course of the lane at least partially;
• calculating further data for specifying a course of a part of the lane dependent on the local map data, wherein the part of the lane crosses the intersection;
• and
• controlling a steering system of the vehicle dependent on the further data and sensor data generated by means of the sensor system in order to keep the vehicle in the lane when crossing the intersection.

A computer program product having instructions, wherein an executing of the instructions by one or more processors initiates the one or more processors to execute:

• receiving local map data by means of the receiver from a transmitter located within a zone of an intersection, wherein the local map data specifies a course of the lane at least partially;
• calculating further data for specifying a course of a part of the lane dependent on the local map data, wherein the part of the lane crosses the intersection;
• and
• controlling a steering system of the vehicle dependent on the further data and sensor data generated by means of the sensor system in order to keep the vehicle in the lane when crossing the intersection.

A vehicle comprising:

• a driver-assistance system for keeping the vehicle in a lane of a road, the driver-assistance system having:
• a sensor system,
• a receiver configured to receive local map data from a transmitter located within a zone of an intersection, wherein the local map data specifies a course of the lane at least partially, and
• a control system configured to:
• calculate further data for specifying a course of a part of the lane dependent on the local map data, wherein the part of the lane leads at least partially across the intersection, and
• control a steering system of the vehicle dependent on the further data and sensor data generated by the sensor system in order to keep the vehicle in the lane when crossing the intersection.
