Abstract
A device and a method for cruise control in a motor vehicle are described, the cruise control being performable as a constant-distance regulation if at least one preceding vehicle has been detected by a radar sensor, or cruise control being performable as a constant-speed regulation if no preceding vehicle has been detected by a radar sensor. Measured object values for detected objects are supplied to the cruise control, which includes a computing means which determines an acceleration gradient for each measured value of each object and adds the individual acceleration gradients of the measured values for each object and outputs the added-up acceleration gradients for the object selected as the target object.

11. A cruise control device for speed control in a motor vehicle having a radar sensor, the speed control being a constant-distance control if at least one preceding vehicle is detected by the radar sensor, the speed control being a constant-speed regulation if no preceding vehicle is detected by the radar sensor, the device comprising:
-
means for receiving measured object values for detected objects;
a computing device for determining an acceleration gradient for each measured value of each object and for adding-up the acceleration gradients of the measured values for each object; and
means for outputting the added-up acceleration gradient for an object selected as a target object. - View Dependent Claims (12, 13, 14, 15)

16. A method for speed control in a motor vehicle having a radar sensor, the speed control being a constant-distance regulation if at least one preceding vehicle is detected by the radar sensor, the speed control being a constant-speed regulation if no preceding vehicle is detected by the radar sensor, the method comprising:
-
supplying measured object values for detected objects to a cruise control;
determining an acceleration gradient for each measured value of each object, using a computing device;
adding-up the acceleration gradients of the measured values for each object; and
outputting the added-up acceleration gradient for an object selected as a target object. - View Dependent Claims (17, 18, 19, 20)
