Abstract

A velocity-regulating system for motor vehicles has an electronic control device that produces control signals for regulating the velocity of the motor vehicle at a pre-specified target velocity and/or at a pre-specified distance from a preceding target object. The velocity-regulating system has an operating element whose actuation causes an intervention that influences the velocity regulation. The operating element is embodied as a touch-sensitive button that, when the button is pressed, produces a first intervention that influences the velocity regulation, and that, when the button is only touched, for the period during which button is touched, produces a second intervention that influences the active velocity regulation. Once the touching has ended, the original velocity regulation is continued.
