Abstract
The invention is directed to a method and apparatus for influencing the driving speed of a motor vehicle. The apparatus includes an electronic control unit which includes a microcomputer and a memory. In the control unit, a controller is implemented for the driving speed of the vehicle which is chargeable with an adapted proportional amplification and an integral amplification in dependence on selected and actual driving conditions of the vehicle. The driving modes of "accelerate", "decelerate" and "resume" are automatically carried out pursuant to the steps of the method. Smooth transitions between different speeds are obtained by operating the controller as a proportional controller during acceleration phases.
