Abstract

A method of cruise control and distance regulation in motor vehicles, in which the distance from a vehicle driving in front is measured, and at least two operating modes (e.g., ACC and stop and go) are provided for the distance regulation, these modes being activatable in different overlapping speed ranges, and in which it is possible to switch between these operating modes in at least one direction only by a command by the driver. The speed of the vehicle driving in front is extrapolated into the future on the basis of the speed of one's own vehicle and the measured distance data and/or the relative speed data, and a switch prompt is output to the driver when the extrapolated speed is outside the allowed range for the current mode, and the current speed is within the allowed range for the other mode.
