The takeover prompt is activated and deactivated as a function of a fixed minimum distance between the distance- and speed-controlled vehicle and the target object and/or a relative speed-dependent minimum distance between the distance- and speed-controlled vehicle and a target object and/or a maximum vehicle deceleration producible by the distance and speed controller. ## Claims ### Claim at position 1 1-8. (canceled) ### Claim 9 A method for notifying a driver of a motor vehicle equipped with an adaptive distance and speed controller, comprising: one of activating or deactivating a takeover prompt which informs the driver that the vehicle is coming critically close to a target object; wherein the activation or deactivation of the takeover prompt occurs as a function of at least one of: i) a fixed minimum distance between a distance-controlled and speed-controlled vehicle and the target object, ii) a relative speed-dependent minimum distance of the distance-controlled and speed-controlled vehicle in relation to the target object, and iii) a maximum vehicle deceleration producible by the distance and speed controller. ### Claim 10 (depends on 9) The method as recited in claim 9, wherein the takeover prompt is at least one of: a visual display in a field of view of the driver, and an acoustic signal in an interior of the vehicle. ### Claim 11 (depends on 9) The method as recited in claim 9, wherein the takeover prompt is further output when the driver overrides the distance and speed controller. ### Claim 12 (depends on 9) The method as recited in claim 9, wherein activation thresholds and deactivation thresholds of the takeover prompt are not identical. ### Claim 13 (depends on 9) The method as recited in claim 9, wherein the distance and speed controller emits and receives radar signals, with the aid of which preceding vehicles can be recognized as target objects. ### Claim 14 A device for the distance and speed control of a motor vehicle, comprising: an arrangement which outputs a takeover prompt, informing a driver that the vehicle is coming critically close to a target object, the arrangement being configured so that activation and deactivation of the takeover prompt occurs as a function at least one of: i) a fixed minimum distance between the distance- and speed-controlled vehicle and the target object, ii) a relative speed-dependent minimum distance between the distance- and speed-controlled vehicle and the target object, and iii) a maximum vehicle deceleration producible by the distance and speed controller. ### Claim 15 (depends on 14) The device as recited in claim 14, further comprising: a display device, the display device displaying the takeover prompt in a field of view of the driver. ### Claim 16 (depends on 14) The device as recited in claim 14, further comprising: an acoustic device, the takeover prompt being about output as an acoustic signal by the acoustic device in an interior of the vehicle. ### Claim 17 (depends on 14) The device as recited in one of claim 14, further comprising: a radar device, the radar device configured to emit and receive radar signals so that a preceding vehicle can be recognized as a target object.
