Patent ID: 6939263

Claim:
A control device for a hybrid vehicle having an engine and a motor for outputting power for driving said vehicle, wherein a regenerative brake is used during deceleration traveling of said vehicle in accordance with a deceleration state thereof, and said engine includes at least one deactivatable cylinder which is deactivatable during deceleration traveling of said vehicle, said control device comprising: a deactivation determining section for determining whether said deactivatable cylinder is allowed to be deactivated in accordance with a traveling state of said vehicle; a deactivation cancellation determining section for canceling cylinder deactivation during deactivation operation; an intake pressure sensing section for measuring air pressure in an intake passage of said engine; and a control valve operating section for opening/closing a secondary air passage of said engine for providing auxiliary air into said intake passage by operating a secondary air valve, wherein said control valve operating section operates said secondary air valve so as to close said secondary air passage when the intake pressure measured by said intake pressure sensing section is a negative value lower than a predetermined first threshold during deceleration traveling of said vehicle.
