1. 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 to prompt the driver to perform a brake intervention;
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, and wherein the takeover prompt is further output when the driver overrides the distance and speed controller by depressing an accelerator and the vehicle comes critically close to the target object, andwherein the takeover prompt is deactivated to inform the driver that the distance and speed controller is able to avoid a collision with the target object.

Abstract
A device and a method for notifying the driver of a motor vehicle, equipped with an adaptive distance and speed controller, by activating a takeover prompt, informing the driver that the vehicle is coming critically close to a target object. 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.

12. 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 to prompt the driver to perform a brake intervention, 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, wherein the takeover prompt is further output when the driver overrides the distance and speed controller by depressing an accelerator and the vehicle comes critically close to the target object, and wherein the takeover prompt is deactivated to inform the driver that the distance and speed controller is able to avoid a collision with the target object.- View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)
