Patent number: 8406980Abstract: An air-fuel ratio control device includes an air-fuel ratio sensor provided upstream from a three-way catalyst, and an oxygen sensor provided downstream from the three-way catalyst. The air-fuel ratio control device controls the fuel supply amount based on the output from the air-fuel ratio sensor, and compensates for errors in the air-fuel ratio sensor by correcting the fuel supply amount based on the output from the oxygen sensor. The fuel supply correction amount is calculated based on an integral term that integrates the deviation between the output from the downstream air-fuel ratio sensor and the target air-fuel ratio. When a fuel supply adjustment control is executed, the value of the integral term in the sub-feedback control is not updated for a predetermined period after the fuel supply adjustment control ends. The actual air-fuel ratio is thus brought to the target air-fuel ratio in an appropriate manner.Type: GrantFiled: April 11, 2008Date of Patent: March 26, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Norihisa Nakagawa, Takahiko Fujiwara, Taiga Hagimoto, Junichi Kako, Naoto Kato, Shuntaro Okazaki

Patent number: 8209104Abstract: This invention is intended to ensure that a control device for a vehicle drive unit is capable of realizing desired torque by making the main-actuator and sub-actuator collaborate adequately while holding the interposition of the sub-actuator as low as possible. For this end, a future target of torque that is going to be output from the engine and a realization timing of the future target are taken as reservation information for reserving engine torque regulation. Next, the required period, which is required to realize the future target when a main-actuator (a throttle) is operated to regulate the torque, is computed from a current engine operating condition. Then, the operation of the main-actuator is started at the timing preceding the realization timing by the required period for realizing the future target.Type: GrantFiled: October 1, 2008Date of Patent: June 26, 2012Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shinichi Soejima, Junichi Kako, Kaoru Ohtsuka, Hiroyuki Tanaka, Keisuke Kawai
