Abstract

A cruise control road speed control device provides an attenuating member connected between the speed control and the fuel injection volume adjusting member. The attenuating member feeds the controller output signal in a lower value range to the adjusting member after attenuation. This measure suppresses the undesired rpm oscillations and thus, even with cruise control operation at low engine loads, permits satisfactory driving comfort without perceptible juddering effects. The cruise control can be used for controlling the road speed of commercial vehicles with Diesel engines and automatic transmissions.
