1. A control system for one's own motor vehicle, comprising an electronic controller configured to execute a control method, based on environmental data obtained from at least one environmental sensor associated with the one's own motor vehicle, to detect lanes, lane demarcations, lane markings, other motor vehicles and/or objects in an area in front of, laterally next to, and/or behind the one's own motor vehicle, wherein the at least one environment sensor is configured to provide the electronic controller of the control system with environmental data reflecting the area in front of, laterally next to, and/or behind the one's own motor vehicle, and wherein the electronic controller is further configured to execute the control method to:
determine, from the environmental data provided, a position and a speed of a first motor vehicle which is traveling directly ahead of the one's own motor vehicle in a first lane, wherein the one's own motor vehicle is located in the first lane;
determine, from the environmental data provided, a position and a speed of a second motor vehicle, which is traveling in an adjacent lane which is adjacent to the first lane;
detect, from the environmental data provided, a position of a third motor vehicle which is traveling directly ahead of the first motor vehicle in the first lane and a position of a fourth motor vehicle which is traveling ahead of the second motor vehicle in the adjacent lane;
detect, from the environment data provided, whether a traffic jam situation exists;
determine that a zipper situation exists in a case where the fourth motor vehicle merges from the adjacent lane to the first lane into a gap between the first motor vehicle and the third motor vehicle and the traffic jam situation exists; and
in a case where it is determined that the zipper situation exists, increase a target distance of the one's own motor vehicle to the first motor vehicle in a case where an amount of a relative speed of the second motor vehicle relative to the one's own motor vehicle or relative to the first motor vehicle is less than a predefined first value, and the second motor vehicle is located between the one's own motor vehicle and the first motor vehicle in a longitudinal direction which extends along the adjacent lane.
