Abstract
A hybrid vehicle control apparatus is provided which can improve fuel consumption. There is provided: a cylinder cut-off determination section for determining whether all cylinders should be cut off; a cylinder cut-off cancellation determination section for determining whether cylinder cut-off cancellation conditions have been satisfied; a cylinder cut-off execution section for operating a spool valve when the cylinder cut-off determination section determines that cylinder cut-off is possible; and a cylinder cut-off control section for cutting off the cylinders of the engine based on the operating conditions of the cylinder cut-off determination section, the cylinder cut-off cancellation determination section and the cylinder cut-off execution section. When the voltage of an auxiliary battery, being the drive source of the spool valve, is at or greater than a predetermined voltage, and the oil temperature is within a predetermined range, the cylinder cut-off determination section determines that cylinder cut-off is possible.
