Publication number: 20130024096Abstract: The present invention has an object to enable a torque as required to be realized without being influenced by an operation state of an IN-VVT, which is a variable valve timing mechanism which changes a valve timing of an intake valve. For this purpose, a control device for an internal combustion engine provided by the present invention stores data that defines a relationship between an air quantity and a torque in an MBT in association with the operation state of the IN-VVT, and calculates a target air quantity for realizing a required torque based on the data. The control device calculates an actual air quantity which is actually realized by an operation of a throttle when operating the throttle to realize the target air quantity.Type: ApplicationFiled: April 9, 2010Publication date: January 24, 2013Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Noboru Takagi, Hiromitu Seo, Eiichiro Kido, Takamitsu Mizutani, Hirokazu Ando
