Abstract

A method and apparatus for limiting the speed of a motor vehicle in which the power applied to the vehicle wheels is controlled even when the actual speed is within a range of permitted speeds, but a speed demanded by the driver is in a speed range to be avoided. By way of the control intervention, the actual speed is, in this case, brought to the limiting speed in accordance with a specified open-loop control characteristic. When the actual speed is near the limiting speed, the system switches over to an open-loop speed-control, and when the speed demanded by the driver is within the range of permitted speeds, this requirement of the driver is used to determine the speed.
