A method for assisting a driver of a host vehicle in potential lane change situations, comprising the steps of: - producing sensor data by at least one sensor physically sensing the environment of the host vehicle, - determining whether a gap on a neighboring lane of the host vehicle exists, - generating, based on the gap determination, a recommendation information signal regarding feasibility of a lane change of the host vehicle to this neighboring lane, and - outputting a notification for the host vehicle's driver and/or, in case that a lane change is feasible, generating signals for performing an autonomous lane change on the basis of the recommendation information signal by the host vehicle, characterized in that the method further comprises the steps of: - predicting, based on the produced sensor data, future movement behavior of at least one sensed target object before the start of the movement behavior of said at least one sensed target object; wherein in said generating step, the feasibility is determined by computationally combining the determination result of the existence of a gap and the predicted future movement behavior, wherein said recommendation information signal is generated if the neighboring lane of the host vehicle is free or the gap on the neighboring lane exists and if the neighboring lane of the host vehicle would fit better for the predicted future movement behavior; - predicting, based on the produced sensor data, the existence of the gap on the neighboring lane for the future; and - performing, if the neighboring lane of the host vehicle would fit better for the predicted future movement behavior, an adaptation of the host vehicle's speed autonomously to enable changing lane into the gap when it becomes available. - producing sensor data by at least one sensor physically sensing the environment of the host vehicle, - determining whether a gap on a neighboring lane of the host vehicle exists, - generating, based on the gap determination, a recommendation information signal regarding feasibility of a lane change of the host vehicle to this neighboring lane, and - outputting a notification for the host vehicle's driver and/or, in case that a lane change is feasible, generating signals for performing an autonomous lane change on the basis of the recommendation information signal by the host vehicle, - predicting, based on the produced sensor data, future movement behavior of at least one sensed target object before the start of the movement behavior of said at least one sensed target object; wherein in said generating step, the feasibility is determined by computationally combining the determination result of the existence of a gap and the predicted future movement behavior, wherein said recommendation information signal is generated if the neighboring lane of the host vehicle is free or the gap on the neighboring lane exists and if the neighboring lane of the host vehicle would fit better for the predicted future movement behavior; - predicting, based on the produced sensor data, the existence of the gap on the neighboring lane for the future; and - performing, if the neighboring lane of the host vehicle would fit better for the predicted future movement behavior, an adaptation of the host vehicle's speed autonomously to enable changing lane into the gap when it becomes available.
