Abstract
In the motor vehicle speed control arrangement, the distance to an object detected in front of the motor vehicle is detected by a distance sensor and supplied to a control unit which forms one or more manipulated variables for setting the driving speed of the motor vehicle as a function of at least a desired distance to the detected object which is determined at least from the instantaneous driving speed and/or a prescribed desired speed. In order to improve the comfort performance of the speed control, the arrangement provides that, in the event of a loss of detection of the object by the distance sensor, the control unit determines the reason for the loss of detection of the object and forms the manipulated variables for setting the driving speed as a function of the reason for the loss of detection.
