Abstract
The invention relates to a control method for establishing in a motor vehicle, on the basis of environment data obtained by one or more environment sensors present on the motor vehicle, that, white an ACC system is active in one'"'"'s own motor vehicle, another motor vehicle, which is moving relative to one'"'"'s own motor vehicle in a neighboring lane, has a tendency to change to the lane of one'"'"'s own motor vehicle. The environment sensor are designed to provide environment data representing the area laterally ahead of, laterally next to and/or laterally behind one'"'"'s own vehicle. As soon as the environment data representing said tendency exceed a predefined significance threshold, autonomous driving operation interventions (i) are trigged to increase the distance to another motor vehicle which is moving relative to one'"'"'s own motor vehicle in the same lane ahead of one'"'"'s own motor vehicle, and/or (ii) the driving speed of one'"'"'s own motor vehicle is reduced if no other motor vehicle moving relative to one'"'"'s own motor vehicle in the same lane ahead of one'"'"'s own motor vehicle is detected to allow another motor vehicle that is moving relative to one'"'"'s own motor vehicle in the neighboring lane to change lane from the neighboring lane to the lane of one'"'"'s own motor vehicle.

- 15. A control system that is configured and intended for use in a motor vehicle, including a surroundings sensor (Re) laterally in front in the corner area of the motor vehicle, having a monitoring area (Ua), and a surroundings sensor (Rv) situated in front in the middle area of the motor vehicle, having a monitoring area (Ub), wherein the surroundings sensors (Rv, Re) are configured for continuously detecting the area laterally in front of, laterally to the side of, and laterally behind the host motor vehicle (ego) in order to determine the speed, location as a function of time, and the travel direction of another vehicle (alter_1), detecting a transverse movement of the other vehicle in the direction from the other lane into the host lane, and detecting the status of a travel direction change indicator of the other vehicle, wherein the control system is configured for determining, while an ACC device is active in the host motor vehicle, that the other motor vehicle (alter_1) that is moving relative to the host motor vehicle (ego) in an adjacent lane has a tendency to change to the lane of the host motor vehicle (ego), wherein the surroundings sensors (Rv, Re) are configured for continuously providing to an electronic control system (ECU) of the control system the surroundings data that reflect the area laterally in front of, laterally to the side of, and laterally behind the host motor vehicle (ego), and the control system is at least configured and intended, as soon as the surroundings data reflecting this tendency have exceeded a predetermined significance threshold, by autonomous driving operation interventions to (i) increase the distance from an additional other motor vehicle (alter_2) that is moving relative to the host motor vehicle (ego) in the same lane ahead of the host motor vehicle (ego), and/or (ii) reduce the driving speed of the host motor vehicle (ego) if the surroundings sensors detect no additional other motor vehicle (alter_2) that is moving relative to the host motor vehicle (ego) in the same lane ahead of the host motor vehicle (ego), in order to give the other motor vehicle (alter_1) that is moving relative to the host motor vehicle (ego) in the adjacent lane the opportunity to make a lane change from the adjacent lane to the lane of the host motor vehicle (ego).
- 19. A control method that is based on surroundings data obtained with a surroundings sensor (Re) laterally in front in the corner area of the motor vehicle, having a monitoring area (Ua), and a surroundings sensor (Rv) situated in front in the middle area of the motor vehicle, having a monitoring area (Ub), wherein the surroundings sensors (Rv, Re) continuously detect the area laterally in front of, laterally to the side of, and laterally behind the host motor vehicle (ego) in order to determine the speed, location as a function of time, and the travel direction of another vehicle, detecting a transverse movement of the other vehicle in the direction from the other lane into the lane of the host motor vehicle, and detecting the status of a travel direction change indicator of the other vehicle, wherein the control system determines, using the surroundings data obtained from the surroundings sensors (Rv, Re), while an ACC device is active in the host motor vehicle, that the other motor vehicle (alter_1) that is moving relative to the host motor vehicle (ego) in an adjacent lane has a tendency to change to the lane of the host motor vehicle (ego), wherein the surroundings sensors (Rv, Re) are configured for continuously providing surroundings data that reflect the area laterally in front of, laterally to the side of, and laterally behind the host motor vehicle (ego), and as soon as the surroundings data reflecting this tendency have exceeded a predetermined significance threshold, autonomous driving operation interventions are triggered to (i) increase the distance from an additional other motor vehicle (alter_2) that is moving relative to the host motor vehicle (ego) in the same lane ahead of the host motor vehicle (ego), and/or (ii) reduce the driving speed of the host motor vehicle (ego) if the surroundings sensors detect no additional other motor vehicle (alter_2) that is moving relative to the host motor vehicle (ego) in the same lane ahead of the host motor vehicle (ego), in order to give the other motor vehicle (alter_1) that is moving relative to the host motor vehicle (ego) in the adjacent lane the opportunity to make a lane change from the adjacent lane to the lane of the host motor vehicle (ego).
