Patent ID: 6934610

Claim:
A control apparatus for a hybrid vehicle comprising an engine and electric motor as driving power of the hybrid vehicle, wherein the electric motor carries out regenerative braking depending on the deceleration state of the hybrid vehicle, and said engine comprises cylinders each capable of executing a deactivation operation, the control apparatus for a hybrid vehicle comprising: a cylinder deactivated operation determination device for determining whether it is appropriate to execute the cylinder deactivated operation depending on the driving conditions of the vehicle; a regeneration amount calculating device for detecting a deceleration state of the vehicle and for calculating the amount of regeneration due to said electric motor during deceleration, and the regeneration amount calculating device further comprises: a compensation amount calculating device for calculating a compensation amount associated with cylinder operation energy in terms of the engine rotation speed, which is recovered by the cylinder deactivated operation executed by said cylinder deactivated operation determination device while the electric motor is in the deceleration regeneration, wherein said electric motor executes regeneration so as to generate an amount of regeneration energy determined both by said regeneration amount calculating device and said compensation amount calculating device.
