ABSTRACT:
An FI/AT/MGECU, in a cylinders deactivation operating state during cruise control where the vehicle speed follows a predetermined target speed, regulates renewal on an addition side of a power plant required torque final value TQPPRQF, and in a case where a flag value of a torque hold flag F_CCKTQS showing to hold the power plant required torque final value TQPPRQF to a predetermined torque value related to a cylinder deactivation upper limit torque TQACS is a “1” (YES side in step S33), when the vehicle speed VP is decreased less than a value obtained by subtracting from a set vehicle speed VC which is the target vehicle speed during cruise control, a predetermined vehicle speed #ΔV (for example, #ΔV=3 km/h or the like) (YES side in step S35), the internal-combustion engine E is switched from a cylinders deactivation operation to an all cylinders operation. The fuel consumption efficiency is thus improved while keeping occupants in the vehicle from feeling discomfort with respect to travelling behavior.
