Patent number: 8515646Abstract: A control apparatus of an internal combustion engine capable of appropriately reflecting various requests relating to the performance of the internal combustion engine. Specifically, the control device of the internal combustion engine acquires various requests relating to the performance of the internal combustion engine, and sets restricted ranges of the value of the control variable in accordance with the details of the requests. At this moment, the control device temporally changes the set restricted ranges for specific requests associated with the time integral value of the control variable rather than the instantaneous value of the control variable. Subsequently, the control device determines a final restricted range on the basis of the overlap between the restricted ranges set for each request, and determines the target value of the control variable in the final restricted range.Type: GrantFiled: February 25, 2010Date of Patent: August 20, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kota Sata, Yasuhiro Oi, Shinichi Soejima, Koichi Ueda, Shuntaro Okazaki, Satoshi Yoshizaki

Patent number: 8448504Abstract: A exhaust catalyst temperature estimating apparatus is provided for estimating a exhaust catalyst temperature of a exhaust catalyst in which a catalyst is loaded on a support and arranged in an exhaust system of an internal combustion engine. The exhaust catalyst temperature estimating apparatus estimates the exhaust catalyst temperature using a first model formula to calculate a current exhaust catalyst temperature of the exhaust catalyst based on a parameter corresponding to a current exhaust gas status. The first model formula is empirically determined such that a exhaust catalyst temperature that excludes heat generated by a chemical reaction is calculated for the parameter by using the support prior to being loaded with the catalyst, or is a physical formula of the support prior to being loaded with the catalyst such that a exhaust catalyst temperature excludes heat generated by a chemical reaction is calculated for the parameter.Type: GrantFiled: October 7, 2010Date of Patent: May 28, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kota Sata, Koichi Ueda
