Control device for hybrid vehicles

A control apparatus for a hybrid vehicle comprising the driving power sources composed of an engine and a motor, wherein the motor generates regenerative power during deceleration depending on the deceleration state of the vehicle and the engine is a type of engine capable of executing an all cylinders deactivated operation, and

• wherein the control apparatus comprises:
• a cylinder deactivation determination means for determining whether it is appropriate for said engine to enter a cylinder deactivated operation based on driving conditions of the vehicle;
• a cylinder deactivation release determination means for determining whether it is appropriate for said engine during the cylinder deactivated operation to release the cylinder deactivated operation based on vehicle conditions;
• a cylinder deactivation execution means for operating an actuator for executing the cylinder deactivated operation, when said cylinder deactivation determination means executes the cylinder deactivated operation;
• an operation appropriateness determination means for determining whether the operation of the actuator is appropriate;
• and
• a cylinder deactivation control means for controlling the deactivated operation of said engine based on said cylinder deactivation determination means, said cylinder deactivation release determination means, said cylinder deactivation execution means, and said operation appropriateness determination means.
