ABSTRACT:
A method and a device for controlling the speed of a motor vehicle and its distance from a vehicle travelling in front are provided. The speed is controlled as long as no vehicle travelling in front is located within a prescribed detection area in front of the vehicle and the distance from the vehicle travelling in front is controlled if a vehicle is located in the detection area. The desired distance for the distance control is set after an instruction for a lane change to the left has been triggered, to a value which is smaller than the value before this instruction was triggered, but is at least as large as a prescribed minimum distance. Alternatively, the actual acceleration of the vehicle is limited to a prescribed maximum value if a vehicle travelling in front moves out of the prescribed detection area in front of the vehicle during the time that an instruction for a lane change to the right is set. In this way, fast overtaking maneuvers can be performed within the control and/or lane changes to the right can be carried out without undesired acceleration effects.
