A motor vehicle cruise control in which the control gain is relatively high in the normal mode of operation and relatively low in the resume and acceleration modes of operation. In the normal mode of operation, a position command for an engine throttle actuator is retrieved from a high gain look-up table as a function of the vehicle speed error. In the resume and acceleration modes of operation, the position command is retrieved from a low gain look-up table as a function of the vehicle speed error. Changes in the position command at transitions between the low gain and high gain tables are eliminated through a suitable offset of the speed error used in the position command look-up, thereby assuring a smooth transition between the normal mode and the resume or acceleration modes.
