CONTROL SYSTEM AND METHOD FOR ALLOWING ANOTHER MOTOR VEHICLE TO PULL IN FRONT FROM A NEIGHBORING LANE DURING ACC OPERATION OF ONE'S OWN MOTOR VEHICLE
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, while 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 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.
The invention relates to a control system which is equipped and designed for use in a motor vehicle, to determine, on the basis of environment data obtained by one or more environment sensors present on the motor vehicle, a point in time as of which a safe lane change from a fast lane to an adjoining slower lane is possible. The environment sensors are designed to provide environment data representing the area laterally ahead of, laterally next to and/or laterally behind the vehicle to an electronic control unit of the control system. The control system is at least equipped and designed to determine, during a predefined interval or continuously, in the electronic control unit driving data representing the driving situation of one's own motor vehicle from sensors present in one's own motor vehicle. One or more other vehicles using the road laterally ahead of, laterally next to and/or laterally behind one's own motor vehicle are detected by means of the environment sensors during the predefined interval or continuously in order to determine characteristic variables relating to the driving situation(s) of the one or more other vehicles. On the basis of the driving data representing the driving situation of one's own vehicle and on the basis of the characteristic variables relating to the driving situation(s) of the one or more other vehicles, it is determined whether a safety-critical area laterally next to and/or laterally behind one's own motor vehicle is free of said other vehicle(s) and the finding is output optically, haptically and/or acoustically to the driver of one's own vehicle. The control system is equipped and designed to determine, on the basis of the driving data representing the driving situation of one's own vehicle and on the basis of the characteristic variables relating to the driving situation(s) of the one or more other vehicles, in the electronic control unit the point in time as of which a safe lane change is possible. This point in time is considered to be reached when the electronic control unit determines that a rear edge of one's own motor vehicle has gone past a front edge of the other vehicle and past a safety distance adapted to legal and/or physical conditions.
