Abstract
Integration of vehicle speed and engine control functions in an automotive vehicle internal combustion engine controller compensates for mechanical lash between a cruise control actuator and an engine intake air valve without sacrificing control responsiveness through a parallel control approach, and improves overall control stability and controllability in the absence of mechanical lash through a selective control approach established to provide for smooth transitions between control modes. Improvement in the integration of deceleration fuel cutoff control with cruise control operates to prevent torque disturbances caused by control transitions in sensitive engine operating regions.
