Patent number: 9399966Abstract: An ECU for controlling an engine counts an unused time TIM of engine in a low-temperature environment. If the unused time TIM is shorter than a predetermined reference value, the ECU sets idle speed immediately after start of operation of the engine to a first idle speed, and if the unused time TIM is longer than the reference value, sets the idle speed to a second idle speed higher than the first idle speed. If duration of the second idle speed exceeds a reference period determined by state of driving of the vehicle, the ECU sets the idle speed to be lower than the second idle speed. In this manner, increased vibration in idling operation in a low-temperature environment can be prevented.Type: GrantFiled: February 22, 2012Date of Patent: July 26, 2016Assignee: Toyota Jidosha Kabushiki KaishaInventors: Kenji Hayashi, Takumi Anzawa, Eiji Fukushiro, Katsuhiko Yamaguchi

Patent number: 9228514Abstract: An ECU for controlling an engine counts the continued period of stopping the engine in a low-temperature environment. The ECU sets the idle rotational speed at a first idle rotational speed when the stopped period is below a predetermined threshold value, and at a second idle rotational speed higher than the first idle rotational speed when the stopped period exceeds the reference value. Accordingly, resonance at the driving force transmission system during idle operation can be prevented even in the case where a mount employed for attaching the engine to the vehicle is hardened as a result of undergoing a low-temperature environment for a long period of time, and the resonant rotational speed of the driving force transmission system including the engine varies.Type: GrantFiled: March 31, 2011Date of Patent: January 5, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kenji Hayashi, Takumi Anzawa, Eiji Fukushiro, Katsuhiko Yamaguchi

Patent number: 7974759Abstract: A drive force control portion firstly changes a front wheel command torque (Tfcm) and a rear wheel command torque (Trcm) so that each command torque reaches a torque in a predetermined range. The drive force control portion releases the restriction on the change of the rear wheel command torque (Trcm) after the front wheel command torque (Tfcm) and the rear wheel command torque (Trcm) have entered the predetermined range. Therefore, it becomes possible to improve the vehicle stability in a vehicle that includes a plurality of power sources that drives a plurality of wheels.Type: GrantFiled: February 6, 2007Date of Patent: July 5, 2011Assignees: Toyota Jidosha Kabushiki Kaisha, Denso CorporationInventors: Koichiro Muta, Katsuhiko Yamaguchi, Eiji Masuda

Patent number: 7925417Abstract: An engine ECU (280) and an HV_ECU (320) control a throttle motor (296) such that the throttle valve opening degree (TH) does not exceed a prescribed limit (THlim) and a rate of increase (Ta/t) in the throttle valve opening degree is equal to or lower than a predetermined opening degree increase rate (Tb/t) for a predetermined time period after start-up of the engine (120) is initiated. Thus, power output from the engine is controlled so as not to increase significantly for the predetermined time period. Accordingly, while the engine starts up, a shock that can be felt by a driver can be suppressed. In addition, variation in the amount of air taken into the engine when the engine is started is also reduced, which reduces variation in the amount of pollutants in the exhaust gas emitted while the engine starts up.Type: GrantFiled: February 23, 2007Date of Patent: April 12, 2011Assignees: Toyota Jidosha Kabushiki Kaisha, Denso CorporationInventors: Koichiro Muta, Katsuhiko Yamaguchi, Eiji Masuda

Patent number: 7814743Abstract: In an engine 5 including an in-cylinder injector, the valve timing of an intake valve is retarded by VVT (Variable Valve Timing) controlled by an engine ECU to decompress in a combustion chamber at engine startup. In accordance with a configuration in which the valve timing of intake valve is advanced in a stepped manner from an initial set value, fuel injection from in-cylinder injector is inhibited during the time when the advance is equal to or below a predetermined standard value, and fuel injection from in-cylinder injector is allowed when exceeding the predetermined standard value, whereby degradation in the exhaust emission level in accordance with start time decompression control can be suppressed.Type: GrantFiled: January 25, 2006Date of Patent: October 19, 2010Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshio Inoue, Tsukasa Abe, Shunsuke Fushiki, Mamoru Tomatsuri, Daigo Ando, Keiko Hasegawa, Osamu Harada, Katsuhiko Yamaguchi, Keita Fukui, Yukihiro Sonoda, Koji Morita, Takuji Matsubara, Yusuke Nakayama
