Speed control system for motor vehicles enables actual vehicle speed to be very rapidly controlled to defined desired speed without unwanted overshoots - has proportional stage of regulating unit dependent on engine speed and defined demand acceleration during acceleration phases

摘要

The system has a control device (9) for setting the desired vehicle speed, a measurement device for detecting the actual speed and a regulating unit (21) with at least one proportional stage for generating a control signal for a controller that influences the actual speed (vist) according to the deviation between the actual and desired (vsoll) speeds. The proportional stage of the regulating unit is dependent on the engine speed and a defined demand acceleration (asoll) during acceleration phases.
