Abstract: A reaction force control unit calculates a driver's requested output and then estimates a maximum output that can be generated by an engine in a current cylinder deactivation operation. Next, the reaction force control unit calculates a difference between the maximum output and the requested output as an output difference and then determines whether the output difference has reached a predetermined reaction force start threshold value, and if the determination result is Yes, the reaction force control unit estimates a number of to-be-reactivated cylinders on the basis of the output difference and the current cylinder deactivation operation state. Subsequently, the reaction force control unit sets a target reaction force on the basis of the output difference and the number of to-be-reactivated cylinders, and outputs drive current to a reaction force actuator.

Abstract: In a control system for an internal combustion engine having a plurality of cylinders and mounted on a vehicle, in which the engine operation is switched based on the throttle opening between a full-cylinder operation in which all of the cylinders are operative and a cut-off cylinder operation in which some of the cylinders are inoperative, and a running control including at least a cruise control in which the vehicle runs at a desired vehicle velocity is conducted, the engine operation is switched to the full-cylinder operation when it is determined that deceleration is required in the running control, so as to increase pumping loss (engine loss). With this, it becomes possible to generate the deceleration sufficiently as desired, when, for example, the vehicle descends a downhill.

Abstract: In a control system for an internal combustion engine having a plurality of cylinders whose operation of the engine can be switched between full-cylinder operation during which all of the cylinders are operative and cut-off-cylinder operation during which some of the cylinders are non-operative, and running control, i.e., either cruise control during which the vehicle is controlled to run at a desired vehicle velocity or preceding vehicle follow-up control during which the vehicle is controlled to run at a desired vehicle velocity to maintain a desired inter-vehicle distance from a preceding vehicle, is performed in response to an instruction of an operator, it is judged whether a velocity error between a detected vehicle velocity and the desired vehicle velocity and load of the engine are equal to or smaller than corresponding threshold values. If the result is affirmative when the running control is in progress, it is determined that running condition of the vehicle is stable and the engine operation is switched to the cut-off-cylinder operation, thereby preventing a control hunting from happening, while ensuring to improve fuel consumption by utilizing the cut-off-cylinder operation as much as possible.
